                         A5      PROBLEM DEFINITION/BACKGROUND

In 1991, the Texas Legislature passed the Texas Clean River Act (Senate Bill 818) in response to growing
concerns that water resource issues were not being pursued in an integrated, systematic manner. The act
requires that ongoing water quality assessments be conducted for each river basin in Texas, an approach
that integrates water quality issues within the watershed. The CRP legislation mandates that “each river
authority (or local governing entity) shall submit quality-assured data collected in the river basin to the
commission.” “Quality-assured data” in the context of the legislation means “data that comply with
commission rules for surface water quality monitoring programs, including rules governing the methods
under which water samples are collected and analyzed and data from those samples are assessed and
maintained.” This QAPP addresses the program developed between the LNRA and the TCEQ to carry out
the activities mandated by the legislation. The QAPP was developed and will be implemented in
accordance with provisions of the Quality Management Plan for the Clean Rivers Program (most recent
version).

The purpose of this QAPP is to clearly delineate LNRA QA policy, management structure, and procedures
which will be used to implement the QA requirements necessary to verify and validate the surface water
quality data collected. The QAPP is reviewed by the TCEQ to help ensure that data generated for the
purposes described above are scientifically valid and legally defensible. This process will ensure that data
collected under this QAPP and submitted to the statewide database have been collected and managed in a
way that guarantees its reliability and therefore can be used in water quality assessments and other
programs deemed appropriate by the TCEQ. Project results will be used to support the achievement of
Clean Rivers Program objectives as contained in the Clean Rivers Program Guidance and Reference Guide
FY 2008 -2009.

In response to the passage of the Texas Clean Rivers Act (Senate Bill 818) in 1991, the Lavaca-Navidad
River Authority intensified its water quality monitoring program to be able to assess water quality
conditions within the Lavaca River Basin. The LNRA Surface Water Quality Program routinely collects
monthly field measurements for surface water quality data. Monitoring includes collection of dissolved
oxygen, temperature, pH, specific conductivity, salinity, secchi disk depth (for water clarity), and
hydrological data. Quarterly water samples are taken to GBRA Laboratory for analysis of conventional
parameters. The program was established to collect, store, and make available water quality data for use by
LNRA as well as state and federal water quality managers, cities, consultants, students, and the general
public. Samples are collected from stream, reservoir, and tidally-influenced segments to monitor for the
attainment of designated uses and numerical criteria. Monitoring is also performed periodically to define
water quality and in response to perceived risks of pollution.

The LNRA has collected field measurements in the Basin since 1981. The LNRA Surface Water Quality
Monitoring Program under the Clean Rivers Program added conventional analyses to the existing program.
Sampling at fixed-station sites includes field measurements, and routine water chemistry. The objectives of
monitoring these parameters are to detect and describe spatial and temporal changes, determine impacts of
point and nonpoint sources, and assess compliance with water quality standards. Dissolved oxygen, water
temperature, and pH are field measurements for which water quality criteria are established for each
classified waterbody. Conductivity and salinity (in tidally influenced areas) are monitored to estimate the
total concentration of dissolved ionic matter, evaluate mixing of fresh and salt water in estuaries, and
determine density stratification.

Assessment Area

The Lavaca River Basin (Figure 2) has an area of 2,309 square miles and includes portions (or almost all
in the case of Lavaca county) of six counties (Fayette, Colorado, Wharton, Jackson, Lavaca, and DeWitt).
In 1990, population of the Basin was 41,751 and is projected to be 63,289 in 2040.

Major cities in the Basin are Edna, Ganado, Hallettsville, Moulton, Schulenburg, Shiner, and Yoakum.
The Basin has 188 stream miles, and its headwaters originate at an elevation of 470 feet above mean sea
level (msl). For water quality management purposes, the Basin has been divided into five stream segments
(1601, 1602, 1603, 1604, and 1605).

Lavaca River Basin is bounded on the north and east by the Colorado River Basin, on the west by the
Guadalupe River Basin, on the southeast by the Colorado-Lavaca Coastal Basin, and on the southwest by
the Lavaca-Guadalupe Coastal Basin. About 40 percent of the Basin is drained by the Lavaca River, while
the remaining area is drained by the Navidad River and the Sandy and Mustang Creeks.

Headwaters of the Navidad River rise in the East and West Forks that form at an elevation of 440 feet in
southern Fayette County, join near Oakland at an elevation of 201 feet and then flow southward to Lake
Texana. Waters released from Lake Texana flow through the tidal reach of the Navidad River to its
confluence with the Lavaca River. Lake Texana has a permitted diversion of 74,500 acre-feet/year and
was constructed by the U.S. Bureau of Reclamation for the purpose of municipal, industrial, fish and
wildlife, and recreational users. The Navidad River above Lake Texana has a drainage area of 1,346 square
miles. Headwaters of the Lavaca River originate at an elevation of 470 feet in northwest Lavaca County
and flow southeast and eventually into Lavaca Bay. The confluence of the Lavaca and Navidad Rivers is
about two miles east of Vanderbilt in Jackson County.

The Lavaca River Basin is part of the West Gulf Coast Section of the Coastal Plain Physiographic Province
and includes the Blackland Prairie, Claypan, and Coastal Prairie land-resource areas. In the upper part of
the Basin, the Blackland Prairie is a level to rolling, well-dissected grassland with rapid drainage. The
Claypan area is a gently rolling, moderately dissected post oak-savanna with moderate surface drainage. In
the lower Basin, the Coastal Prairie is a nearly level, practically undissected plain with slow surface
drainage.

The upper Lavaca Basin is underlain by gray clay of the Fleming Formation of Tertiary age which dips
gently toward the Gulf of Mexico. Overlying the Fleming Formation are gravel, sand, silt, and clay of the
Willis, Lissie, and Beaumont Formations each of which are Pleistocene age formations. Recent alluvium
occurs along streams.

The Lavaca River Basin lies within the warm temperate zone and is classified as humid and subtropical
with hot summers. Because of the proximity of the Basin to the Gulf of Mexico and the prevailing
southeasterly wind, a marine climate exists throughout spring, summer, fall, and much of the winter season.
 Mean annual precipitation in the Basin varies from 34 inches along the western boundary to approximately
41 inches along the eastern edge.

Summers are hot and humid with little variation in day-to-day weather conditions, except for occasional
thunderstorms. Winters are short and mild, moderated by polar air masses which frequently push
southward and bring weather to the Basin that alternates from cool, overcast, and drizzly to mild, sunny,
and dry conditions. During summer and early fall, the occurrence of tropical disturbances moving in the
easterly trade winds may bring heavy rains or occasional hurricanes.

Segment 1601 is the tidal portion of the Lavaca River from the mouth of the Lavaca Bay up to a point 8.6
kilometers (5.3 miles) downstream of US 59 in Jackson County. Several small tributaries, the Menefee
Lakes, Redfish Lake, Swan Lake, Redfish Bayou, and Catfish Bayou are included in this segment. The
Redfish and Swan Lakes are important nursery grounds for marine organisms.

Segment 1602 is the Lavaca River above the tidal portion. Many tributaries drain into the Lavaca River:
Dry Creek drains wastewater effluent from Edna, Rocky Creek drains wastewater effluent from Shiner, and
the Big Brushy and Clarks Creeks drain wastewater effluent from Yoakum. Hallettsville and Moulton
dispose of wastewater effluent into the main stem of the Lavaca River.

Segment 1603 is the Navidad River below Lake Texana extending to the confluence of the Lavaca and
Navidad Rivers. The east and west drains along the east and west dikes of Lake Texana drain water into
this segment. The east drain has continuous flow year round. The west drain has intermittent flow.
Additionally, water released from Lake Texana flows through segment 1603 to the Lavaca River, and on
to the Lavaca Bay.

Segment 1604 is Lake Texana. Lake Texana at elevation 44 feet is a 161,085 acre-foot reservoir with
9,727 surface acres. Drainage flows feeding the Lake include the Sandy Creek, Mustang Creeks, Navidad
River, and numerous county drains. The Sandy Creek is an intermittent creek draining a large portion of
the Basin through Jackson, Wharton, Lavaca and Colorado Counties. Flow is mostly return irrigation from
rice fields. The Mustang Creek branches off to the East, West and Middle Mustang and drains a portion of
the Basin from the Garwood Irrigation Service Area to Lake Texana. Wastewater effluent from Ganado
drains into Lake Texana, and the wastewater effluent from the Sheridan community drains into Sandy
Creek.

Segment 1605 is the Navidad River above Lake Texana. Many tributaries drain into the Navidad River.
The wastewater effluent from Schulenburg drains into an unnamed tributary of the Navidad River in the
northern section of the Basin.

Ambient Water Reporting Limits (AWRLs)
The AWRL establishes the reporting specification at or below which data for a parameter must be reported
to be compared with freshwater screening criteria. The AWRLs specified in Table A7.1 are the program-
defined reporting specifications for each analyte and yield data acceptable for the TCEQ’s water quality
assessment. The limit of quantitation (formerly known as the reporting limit) is the minimum level,
concentration, or quantity of a target variable (e.g., target analyte) that can be reported with a specified
degree of confidence. The following requirements must be met in order to report results to the CRP:


              The laboratory’s LOQ for each analyte must be at or below the AWRL as a matter of routine
               practice
LNRA QAPP                                                                                                                                     Page 17

        The laboratory must demonstrate its ability to quantitate at its LOQ for each analyte by running an
         LOQ check standard for each batch of CRP Samples are analyzed.

Laboratory Measurement Quality Control Requirements and Acceptability Criteria are provided in Section
B5.

Precision

Precision is the degree to which a set of observations or measurements of the same property, obtained
under similar conditions, conform to themselves. It is a measure of agreement among replicate
measurements of the same property, under prescribed similar conditions, and is an indication of random
error.

Field splits are used to assess the variability of sample handling, preservation, and storage, as well as the
analytical process, and are prepared by splitting samples in the field. Control limits for field splits are
defined in Section B5.

Laboratory precision is assessed by comparing replicate analyses of laboratory control samples in the
sample matrix (e.g. deioinized water, sand, commercially available tissue)or sample/duplicate pairs in the
case of bacterial analysis. Precision results are compared against measurement performance specifications
and used during evaluation of analytical performance. Program-defined measurement performance
specifications for precision are defined in Table A7.1.

Bias

Bias is a statistical measurement of correctness and includes multiple components of systematic error. A
measurement is considered unbiased when the value reported does not differ from the true value. Bias is
determined through the analysis of laboratory control samples and LOQ Check Standards prepared with
verified and known amounts of all target analytes in the sample matrix (e.g. deioinized water, sand,
commercially available tissue) and by calculating percent recovery. Results are compared against
measurement performance specifications and used during evaluation of analytical performance. Program-
defined measurement performance specifications for bias are specified in Table A7.1.

Representativeness

Site selection, the appropriate sampling regime, the sampling of all pertinent media according to TCEQ
SOPs, and use of only approved analytical methods will assure that the measurement data represents the
conditions at the site. Routine data collected under the Clean Rivers Program for water quality assessment
are considered to be spatially and temporally representative of routine water quality conditions. Water
Quality data are collected on a routine frequency and are separated by approximately even time intervals.
At a minimum, samples are collected over at least two seasons (to include inter-seasonal variation) and
over two years (to include inter-year variation) and include some data collected during an index period
(March 15- October 15). Although data may be collected during varying regimes of weather and flow, the
data sets will not be biased toward unusual conditions of flow, runoff, or season. The goal for meeting
total representation of the water body will be tempered by the potential funding for complete
representativeness.
LNRA QAPP                                                                                                   Page 18
                                                                            4ae06a32-7fd7-469b-9991-006168c78019.doc
Comparability

Confidence in the comparability of routine data sets for this project and for water quality assessments is
based on the commitment of project staff to use only approved sampling and analysis methods and QA/QC
protocols in accordance with quality system requirements and as described in this QAPP and in TCEQ
SOPs. Comparability is also guaranteed by reporting data in standard units, by using accepted rules for
rounding figures, and by reporting data in a standard format as specified in Section B10.

Completeness

The completeness of the data is basically a relationship of how much of the data is available for use
compared to the total potential data. Ideally, 100% of the data should be available. However, the
possibility of unavailable data due to accidents, insufficient sample volume, broken or lost samples, etc. is
to be expected. Therefore, it will be a general goal of the project(s) that 90% data completion is achieved.


A8     SPECIAL TRAINING/CERTIFICATION

New field personnel receive training in proper sampling and field analysis. Before actual sampling or field
analysis occurs, they will demonstrate to the QA Officer (or designee) their ability to properly calibrate
field equipment and perform field sampling and analysis procedures. Field personnel training is
documented and retained in the personnel file and will be available during a monitoring systems audit.

Contractors and subcontractors must ensure that laboratories analyzing samples under this QAPP meet the
requirements contained in section 5.4.4 of the NELAC standards (concerning Review of Requests, Tenders
and Contracts).

Sample Containers
Sample containers (cubitainers) are purchased by LNRA pre-cleaned for conventional parameters and are
disposable. Glass jars are obtained from the GBRA laboratory for Total Organic Carbon samples. Pre-
cleaned and sterilized bacterial bottles are obtained from the GBRA laboratory for Idexx Colilert E. coli
samples, and these bottles are disposable. These bacterial bottles are certified and documentation is
maintained by GBRA. The TOC and bacterial bottles are not re-used. Amber plastic bottles (also obtained
from GBRA) are used routinely for chlorophyll samples. These amber bottles are cleaned by GBRA and
returned to LNRA for re-use. Cleaning procedures appear as Appendix F on page 57.


Processes to Prevent Contamination

Procedures outlined in the TCEQ Surface Water Quality Monitoring Procedures outline the necessary steps
to prevent contamination of samples. These include: direct collection into sample containers, when
possible; clean sampling techniques for metals; and certified containers for organics. Field QC samples
(identified in Section B5) are collected to verify that contamination has not occurred.

Recording Data

For the purposes of this section and subsequent sections, all field and laboratory personnel follow the basic
rules for recording information as documented below:

1.     Write legibly in indelible ink
2.     Changes should be made by crossing out original entries with a single line, entering the changes,
       and initialing and dating the corrections.
3.     Close-out incomplete pages with an initialed and dated diagonal line.

Deficiencies, Nonconformances and Corrective Action Related to Sampling Requirements

Deficiencies are defined as unauthorized deviations from procedures documented in the QAPP or other
applicable documents. Nonconformances are deficiencies which affect data quantity and/or quality and
render the data unacceptable or indeterminate. Deficiencies related to sampling methods requirements
include, but are not limited to, such things as sample container, volume, and preservation variations,
improper/inadequate storage temperature, holding-time exceedances, and sample site adjustments.

Deficiencies are documented in logbooks, field data sheets, etc. by field or laboratory staff and reported to
the cognizant field or laboratory supervisor who will notify the LNRA QAO. The LNRA QAO will initiate
a Nonconformance Report (NCR) to document the deficiency.

The LNRA Project Manager, in consultation with the LNRA QAO (and other affected
individuals/organizations), will determine if the deficiency constitutes a nonconformance. If it is
LNRA QAPP                                                                                                   Page 23
                                                                            4ae06a32-7fd7-469b-9991-006168c78019.doc
determined the activity or item in question does not affect data quality and therefore is not a valid
nonconformance, the NCR will be completed accordingly and the NCR closed. If it is determined a
nonconformance does exist, the LNRA Project Manager in consultation with LNRA QAO will determine
the disposition of the nonconforming activity or item and necessary corrective action(s); results will be
documented by the contractor QAO by completion of a Corrective Action Report.

Corrective Action Reports (CARs) document: root cause(s); impact(s); specific corrective action(s) to
address the deficiency; action(s) to prevent recurrence; individual(s) responsible for each action; the
timetable for completion of each action; and the means by which completion of each corrective action will
be documented. CARs will be included with quarterly progress reports. In addition, significant conditions
(i.e., situations which, if uncorrected, could have a serious effect on safety or on the validity or integrity of
data) will be reported to the TCEQ immediately both verbally and in writing.




B3      SAMPLE HANDLING AND CUSTODY

Sample Tracking

Proper sample handling and custody procedures ensure the custody and integrity of samples beginning at
the time of sampling and continuing through transport, sample receipt, preparation, and analysis.

A sample is in custody if it is in actual physical possession or in a secured area that is restricted to
authorized personnel. The Chain of Custody (COC) form is a record that documents the possession of the
samples from the time of collection to receipt in the laboratory. The following information concerning the
sample is recorded on the COC form (See Appendix D). The following list of items matches the COC
form in Appendix D.

1.      Date and time of collection
2.      Site identification
3.      Sample matrix
4.      Number of containers
5.      Preservative used
6.      Analyses required
7.      Name of collector
8.      Custody transfer signatures and dates and time of transfer
9.      Grab or composite

Sample Labeling

Samples from the field are labeled on the container with an indelible marker. Label information includes:

1.      Site identification
2.      Date of collection
3.      Preservative added, if applicable
4.      Sampling entity

LNRA QAPP                                                                                                      Page 24
                                                                               4ae06a32-7fd7-469b-9991-006168c78019.doc
Sample Handling

The principle of sample custody is being able to account for the sample's integrity from the moment the
portion of water is placed in a sample container until all analytical tests have been completed and any
remaining sample is discarded. This means that proper sample custody is a joint effort of the sampling
crew, the sample transporter, and the laboratory staff.

The chain of custody (COC) record (Appendix D) documents change of possession and requires that the
sample container have the same station number inked onto the sample container as written on the data
sheet. The chain of custody record is signed by the sample collector, and name is printed on COC. These
records have provisions for adding the information discussed in comments 1 through 5 below.

1.     Site and location and point of collection establish where the particular sample became official.

2.     Time and date of collection establishes the start of the chain-of-custody clock. The date of
       shipment adds to this information.

3.     The collection signature establishes the first person with responsibility for the sample's custody.

4.     The presence or absence of added preservatives establishes that the sample will not be significantly
       altered before arrival at the laboratory due to microbial or chemical or physical actions.

5.     A copy of Table A7.1 from the LNRA QAPP is attached to the COC to detail analyses to be run on
       the pertinent samples. A copy of Table B2.1 is also attached as a reminder to keep holding times in
       constant consideration.

The sheet has special places for signatures and printed names and times to monitor changes in possession
of the sample. This is the actual documentation of chain-of-custody. It begins with the sample collector
and ends with the laboratory's designated sample custodian.

Sample integrity must also be protected by preventing sample contamination, whether intentional or
accidental, after the sample is placed in a container. The containers used by the LNRA are purchased pre-
cleaned.

Chain-of-custody documents accompany each sample for transfer of pertinent information. LNRA
transports the samples with COC documents to the GBRA Seguin lab. Samples are transported by LNRA
staff who are cognizant of holding time considerations, and samples are continuously within LNRA’s
custody until they are received by the laboratory. The GBRA laboratory has a designated sample custodian
who examines arriving samples for proper documentation, and proper preservation. The custodian accepts
delivery by signing the final portion of the official chain-of-custody, and a copy of the COC is given to
LNRA. The sample custodian attaches a special laboratory sample number to the sheet and the same
number to the sample container and enters the receipt of the sample into a laboratory sample inventory
logbook. This book notes the date of receipt, the date of completion, and the corresponding sheet number.
Any possible information which could identify the source of the sample is now traceable using the
LNRA QAPP                                                                                                 Page 25
                                                                          4ae06a32-7fd7-469b-9991-006168c78019.doc
inventory logbook which is maintained solely by the sample custodian. GBRA maintains the records of
sample handling according to their quality assurance SOPs

Deficiencies, Nonconformances and Corrective Action Related to Chain-of-Custody

Deficiencies are defined as unauthorized deviations from procedures documented in the QAPP or other
applicable documents. Nonconformances are deficiencies which affect data quantity and/or quality and
render the data unacceptable or indeterminate. Deficiencies related to chain-of-custody include but are not
limited to delays in transfer, resulting in holding time violations; incomplete documentation, including
signatures; possible tampering of samples; broken or spilled samples, etc.

Deficiencies are documented in logbooks, field data sheets, etc. by field or laboratory staff and reported to
the cognizant field or laboratory supervisor who will notify the LNRA QAO. The LNRA QAO will initiate
a Nonconformance Report (NCR) to document the deficiency.

The LNRA Project Manager, in consultation with LNRA QAO (and other affected
individuals/organizations), will determine if the deficiency constitutes a nonconformance. If it is
determined the activity or item in question does not affect data quality and therefore is not a valid
nonconformance, the NCR will be completed accordingly and the NCR closed. If it is determined a
nonconformance does exist, the LNRA Project Manager in consultation with the LNRA QAO will
determine the disposition of the nonconforming activity or item and necessary corrective action(s); results
will be documented by the LNRA QAO by completion of a Corrective Action Report.

Corrective Action Reports (CARs) document: root cause(s); impact(s); specific corrective action(s) to
address the deficiency; action(s) to prevent recurrence; individual(s) responsible for each action; the
timetable for completion of each action; and the means by which completion of each corrective action will
be documented. CARs will be included with quarterly progress reports. In addition, significant conditions
(i.e., situations which, if uncorrected, could have a serious effect on safety or on the validity or integrity of
data) will be reported to the TCEQ immediately both verbally and in writing.


B4      ANALYTICAL METHODS

The analytical methods, associated matrices, and performing laboratories are listed in Table A7.1 of
Section A7. The authority for analysis methodologies under the Clean Rivers Program is derived from the
TSWQS (∞307.1 - 307.10) in that data generally are generated for comparison to those standards and/or
criteria. The Standards state that “Procedures for laboratory analysis will be in accordance with the most
recently published edition of Standard Methods for the Examination of Water and Wastewater, the latest
version of the TCEQ Surface Water Quality Monitoring Procedures, 40 CFR 136, or other reliable
procedures acceptable to the Executive Director.”

Laboratories collecting data under this QAPP are compliant with the NELAC standards. Copies of
laboratory QMs and SOPs are available for review by the TCEQ.

Standards Traceability


LNRA QAPP                                                                                                      Page 26
                                                                               4ae06a32-7fd7-469b-9991-006168c78019.doc
All standards used in the field and laboratory are traceable to certified reference materials. Standards
preparation is fully documented and maintained in a standards log book. Each documentation includes
information concerning the standard identification, starting materials, including concentration, amount used
and lot number; date prepared, expiration date and preparer’s initials/signature. The reagent bottle is
labeled in a way that will trace the reagent back to preparation.


Deficiencies, Nonconformances and Corrective Action Related to Analytical Methods

Deficiencies are defined as unauthorized deviations from procedures documented in the QAPP or other
applicable documents. Nonconformances are deficiencies which affect quantity and/or quality and render
the data unacceptable or indeterminate. Deficiencies related to field and laboratory measurement systems
include but are not limited to instrument malfunctions, blank contamination, quality control sample
failures, etc.

Deficiencies are documented in logbooks, field data sheets, etc. by field or laboratory staff and reported to
the cognizant field or laboratory supervisor who will notify the LNRA QAO. The LNRA QAO will initiate
a Nonconformance Report (NCR) to document the deficiency.

The LNRA Project Manager, in consultation with LNRA QAO (and other affected
individuals/organizations), will determine if the deficiency constitutes a nonconformance. If it is
determined the activity or item in question does not affect data quality and therefore is not a valid
nonconformance, the NCR will be completed accordingly and the NCR closed. If it is determined a
nonconformance does exist, the LNRA Project Manager in consultation with the LNRA QAO will
determine the disposition of the nonconforming activity or item and necessary corrective action(s); results
will be documented by the LNRA QAO by completion of a Corrective Action Report.

Corrective Action Reports (CARs) document: root cause(s); impact(s); specific corrective action(s) to
address the deficiency; action(s) to prevent recurrence; individual(s) responsible for each action; the
timetable for completion of each action; and, the means by which completion of each corrective action will
be documented. CARs will be included with quarterly progress reports. In addition, significant conditions
(i.e., situations which, if uncorrected, could have a serious effect on safety or on the validity or integrity of
data) will be reported to the TCEQ immediately both verbally and in writing.

The TCEQ has determined that analyses associated with the remark codes “holding time exceedance”,
“sample received unpreserved”, “estimated value”, etc. may have unacceptable measurement uncertainty
associated with them. This will immediately disqualify analyses from submittal to SWQMIS. Therefore,
data with these types of problems should not be reported to the TCEQ.


B5      QUALITY CONTROL

Sampling Quality Control Requirements and Acceptability Criteria

The minimum Field QC Requirements are outlined in the TCEQ Surface Water Quality Monitoring
Procedures. Specific requirements are outlined below. Field QC sample results are submitted with the
laboratory data report (see Section A9).
LNRA QAPP                                                                                                      Page 27
                                                                               4ae06a32-7fd7-469b-9991-006168c78019.doc
Field Split - A field split is a single sample subdivided by field staff immediately following collection and
submitted to the laboratory as two separately identified samples according to procedures specified in the
SWQM Procedures. Split samples are preserved, handled, shipped, and analyzed identically and are used
to assess variability in all of these processes. Field splits apply to conventional samples only. LNRA
collects one field split per every 10 conventional samples.

The precision of field split results is calculated by relative percent difference (RPD) using the following
equation:

                                       RPD = (X1-X2)/{(X1+X2)/2)}

A 30% RPD criteria will be used to screen field split results as a possible indicator of excessive variability
in the sample handling and analytical system. If it is determined that elevated quantities of analyte (i.e., > 5
times the RL) were measured and analytical variability can be eliminated as a factor, than variability in
field split results will primarily be used as a trigger for discussion with field staff to ensure samples are
being handled in the field correctly. Some individual sample results may be invalidated based on the
examination of all extenuating information. The information derived from field splits is generally
considered to be event specific and would not normally be used to determine the validity of an entire batch;
however, some batches of samples may be invalidated depending on the situation. Professional judgment
during data validation will be relied upon to interpret the results and take appropriate action. The
qualification (i.e., invalidation) of data will be documented on the Data Summary. Deficiencies will be
addressed as specified in this section under Deficiencies, Nonconformances, and Correction Action related
to Quality Control.




Laboratory Measurement Quality Control Requirements and Acceptability Criteria

Method Specific QC requirements – QC samples, other than those specified later this section, are run (e.g.,
sample duplicates, surrogates, internal standards, continuing calibration samples, interference check
samples, positive control, negative control, and media blank) as specified in the methods. The requirements
for these samples, their acceptance criteria or instructions for establishing criteria, and corrective actions
are method-specific.

Detailed laboratory QC requirements and corrective action procedures are contained within the individual
laboratory quality manuals (QMs). The minimum requirements that all participants abide by are stated
below.


Limit of Quantitation (LOQ) – The laboratory will analyze a calibration standard (if applicable) at the LOQ
on each day Clean Rivers Program samples are analyzed. Calibrations including the standard at the LOQ
will meet the calibration requirements of the analytical method or corrective action will be implemented.


LNRA QAPP                                                                                                     Page 28
                                                                              4ae06a32-7fd7-469b-9991-006168c78019.doc
The LOQ for a solid sample is based on the lowest non-zero calibration standard (as are those for water
samples), the moisture content of the solid sample, and any sample concentration or dilution factors
resulting from sample preparation or clean-up.

To establish solid-phase LOQs to be listed in Table A7.1 of the QAPP, the laboratory will adjust the
concentration of the lowest non-zero calibration standard for the amount of sample extracted, the final
extract volume, and moisture content (assumed to be zero % moisture). Each calculated LOQ will be less
than or equal to the AWRL on the dry-weight basis to satisfy the AWRL requirement for sediment and
tissue analyses. When data are reviewed for consistency with the QAPP, they are evaluated based on this
requirement. Results may not appear to meet the AWRL requirement due to high moisture content, high
concentrations of non-target analytes necessitating sample dilution, etc. These sample results will be
submitted to the TCEQ with an explanation on the data summary as to why results do not appear to meet
the AWRL requirement.

LOQ Check Standard – An LOQ check standard consists of a sample matrix (e.g., deionized water, sand,
commercially available tissue) free from the analytes of interest spiked with verified known amounts of
analytes or a material containing known and verified amounts of analytes. It is used to establish intra-
laboratory bias to assess the performance of the measurement system at the lower limits of analysis. The
LOQ check standard is spiked into the sample matrix at a level less than or near the LOQ for each analyte
for each batch of CRP samples are run.

The LOQ check standard is carried through the complete preparation and analytical process. LOQ Check
Standards are run at a rate of one per analytical batch. A batch is defined as samples that are analyzed
together with the same method and personnel, using the same lots of reagents, not to exceed the analysis of
20 environmental samples.

The percent recovery of the LOQ check standard is calculated using the following equation in which %R is
percent recovery, SR is the sample result, and SA is the reference concentration for the check standard:

                                            %R = SR/SA * 100

Measurement performance specifications are used to determine the acceptability of LOQ Check Standard
analyses as specified in Table A7.1.

Laboratory Control Sample (LCS) - An LCS consists of a sample matrix (e.g., deionized water, sand,
commercially available tissue) free from the analytes of interest spiked with verified known amounts of
analytes or a material containing known and verified amounts of analytes. It is used to establish intra-
laboratory bias to assess the performance of the measurement system. The LCS is spiked into the sample
matrix at a level less than or near the mid point of the calibration for each analyte. In cases of test methods
with very long lists of analytes, LCSs are prepared with all the target analytes and not just a representative
number, except in cases of organic analytes with multipeak responses.


LNRA QAPP                                                                                                    Page 29
                                                                             4ae06a32-7fd7-469b-9991-006168c78019.doc
The LCS is carried through the complete preparation and analytical process. LCSs are run at a rate of one
per analytical batch. A batch is defined as samples that are analyzed together with the same method and
personnel, using the same lots of reagents, not to exceed the analysis of 20 environmental samples.

Results of LCSs are calculated by percent recovery (%R), which is defined as 100 times the measured
concentration, divided by the true concentration of the spiked sample.

The following formula is used to calculate percent recovery, where %R is percent recovery; SR is the
measured result; and SA is the true result:

                                          %R = SR/SA * 100

Measurement performance specifications are used to determine the acceptability of LCS analyses as
specified in Table A7.1.

Laboratory Duplicates – A laboratory duplicate is prepared by taking aliquots of a sample from the same
container under laboratory conditions and processed and analyzed independently. A laboratory control
sample duplicate (LCSD) is prepared in the laboratory by splitting aliquots of an LCS. Both samples are
carried through the entire preparation and analytical process. LCSDs are used to assess precision and are
performed at a rate of one per batch. A batch is defined as samples that are analyzed together with the
same method and personnel, using the same lots of reagents, not to exceed the analysis of 20 environmental
samples.

For most parameters, precision is calculated by the relative percent difference (RPD) of LCS duplicate
results as defined by 100 times the difference (range) of each duplicate set, divided by the average value
(mean) of the set. For duplicate results, X1 and X2, the RPD is calculated from the following equation:

                                  RPD = (X1 - X2)/{(X1+X2)/2} * 100

A bacteriological duplicate is considered to be a special type of laboratory duplicate and applies when
bacteriological samples are run in the field as well as in the lab. Bacteriological duplicate analyses are
performed on samples from the sample bottle on a 10% basis. Results of bacteriological duplicates are
evaluated by calculating the logarithm of each result and determining the range of each pair.

Measurement performance specifications are used to determine the acceptability of duplicate analyses as
specified in Table A7.1. The specifications for bacteriological duplicates in Table A7.1 apply to samples
with concentrations > 10 org./100mL.

Laboratory equipment blank - Laboratory equipment blanks are prepared at the laboratory where collection
materials for metals sampling equipment are cleaned between uses. These blanks document that the
materials provided by the laboratory are free of contamination. The QC check is performed before the
metals sampling equipment is sent to the field. The analysis of laboratory equipment blanks should yield
values less than the LOQ. Otherwise, the equipment should not be used.

Matrix spike (MS) –Matrix spikes are prepared by adding a known mass of target analyte to a specified
amount of matrix sample for which an independent estimate of target analyte concentration is available.

LNRA QAPP                                                                                                 Page 30
                                                                          4ae06a32-7fd7-469b-9991-006168c78019.doc
Matrix spikes are used, for example, to determine the effect of the matrix on a method’s recovery
efficiency.

Percent recovery of the known concentration of added analyte is used to assess accuracy of the analytical
process. The spiking occurs prior to sample preparation and analysis. Spiked samples are routinely
prepared and analyzed at a rate of 10% of samples processed, or one per batch whichever is greater. A
batch is defined as samples that are analyzed together with the same method and personnel, using the same
lots of reagents, not to exceed the analysis of 20 environmental samples. The information from these
controls is sample/matrix specific and is not used to determine the validity of the entire batch. The MS is
spiked at a level less than or equal to the midpoint of the calibration or analysis range for each analyte.
Percent recovery (%R) is defined as 100 times the observed concentration, minus the sample concentration,
divided by the true concentration of the spike.

The results from matrix spikes are primarily designed to assess the validity of analytical results in a given
matrix and are expressed as percent recovery (%R). The laboratory shall document the calculation for %R.
The percent recovery of the matrix spike is calculated using the following equation in which %R is percent
recovery, SSR is the observed spiked sample concentration, SR is the sample result, and SA is the
reference concentration of the spike added:

                                        %R = (SSR - SR)/SA * 100

Measurement performance specifications for matrix spikes are not specified in this document.

The results are compared to the acceptance criteria as published in the mandated test method. Where there
are no established criteria, the laboratory shall determine the internal criteria and document the method
used to establish the limits. For matrix spike results outside established criteria, corrective action shall be
documented or the data reported with appropriate data qualifying codes.

Method blank –A method blank is a sample of matrix similar to the batch of associated samples (when
available) that is free from the analytes of interest and is processed simultaneously with and under the same
conditions as the samples through all steps of the analytical procedures, and in which no target analytes or
interferences are present at concentrations that impact the analytical results for sample analyses. The
method blank is carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination from the analytical process. The analysis of method blanks
should yield values less than the LOQ. For very high-level analyses, the blank value should be less then
5% of the lowest value of the batch, or corrective action will be implemented.

Deficiencies, Nonconformances and Corrective Action Related to Quality Control

Deficiencies are defined as unauthorized deviations from procedures documented in the QAPP.
Nonconformances are deficiencies which affect data quantity and/or quality and render the data
unacceptable or indeterminate. Deficiencies related to quality control include but are not limited to field
and laboratory quality control sample failures.

Deficiencies are documented in logbooks, field data sheets, etc. by field or laboratory staff and reported to
the cognizant field or laboratory supervisor who will notify the LNRA QAO. The LNRA QAO will initiate
a Nonconformance Report (NCR) to document the deficiency.
LNRA QAPP                                                                                                    Page 31
                                                                             4ae06a32-7fd7-469b-9991-006168c78019.doc
The LNRA Project Manager, in consultation with LNRA QAO (and other affected
individuals/organizations), will determine if the deficiency constitutes a nonconformance. If it is
determined the activity or item in question does not affect data quality and therefore is not a valid
nonconformance, the NCR will be completed accordingly and the NCR closed. If it is determined a
nonconformance does exist, the LNRA Project Manager in consultation with the LNRA QAO will
determine the disposition of the nonconforming activity or item and necessary corrective action(s); results
will be documented by the LNRA QAO by completion of a Corrective Action Report.

Corrective Action Reports (CARs) document: root cause(s); impact(s); specific corrective action(s) to
address the deficiency; action(s) to prevent recurrence; individual(s) responsible for each action; the
timetable for completion of each action; and, the means by which completion of each corrective action will
be documented. CARs will be included with quarterly progress reports. In addition, significant conditions
(i.e., situations which, if uncorrected, could have a serious effect on safety or on the validity or integrity of
data) will be reported to the TCEQ immediately both verbally and in writing.


B6      INSTRUMENT/EQUIPMENT TESTING, INSPECTION AND
        MAINTENANCE

All sampling equipment testing and maintenance requirements are detailed in the TCEQ Surface Water
Quality Monitoring Procedures. Sampling equipment is inspected and tested upon receipt and is assured
appropriate for use. Equipment records are kept on all field equipment and a supply of critical spare parts
is maintained.

All laboratory tools, gauges, instrument, and equipment testing and maintenance requirements are
contained within laboratory QM(s).


B7      INSTRUMENT CALIBRATION AND FREQUENCY

Field equipment calibration requirements are contained in the TCEQ Surface Water Quality Monitoring
Procedures. Post-calibration error limits and the disposition resulting from error are adhered to. Data not
meeting post-error limit requirements invalidate associated data collected subsequent to the pre-calibration
and are not submitted to the TCEQ.

Detailed laboratory calibrations are contained within the QM(s).



B8      INSPECTION/ACCEPTANCE OF SUPPLIES AND CONSUMABLES

LNRA staff carefully inspect supplies and consumables before acceptance. Laboratory QM states lab
procedures for inspection and acceptance of supplies and consumables.

This QAPP does not include the use of routine data obtained from non-direct measurement sources.




B10 DATA MANAGEMENT

Data Management Process

Personnel involved in administering and maintaining the data management system are structured as a team.
This team includes the TCEQ, the Authority, and its consultants. The TCEQ provides general oversight,
specifies the needs of the program and assessments, and provides technical guidance and assistance. The
Authority serves as the local program sponsor for the Lavaca River Basin and a clearinghouse for public
outreach or inquiries. Within the Authority’s staff, the QAO coordinates and administers resources for the
analysis, data management, and outreach activities. The QAO coordinates with the GBRA laboratory,
oversees quality assurance of all data, and coordinates with a consultant at the Nueces River Authority
(NRA) who serves as a data quality assurance consultant for the LNRA. The QAO also manages the GIS
database. The Data Manager is responsible for efficient day to day operations including data collection,
data entry, data quality assurance, data management, and data reporting. This data management team is
depicted in the graphic below:

The data management process is illustrated in the flow path below and described in further detail in the
                                         following sections.

                                            Data Path

               Field data stored in data logger and on paper in field notebook >>>

Data logger files downloaded to computer and printed out to keep in permanent hard copy files
                                            >>>

     Quarterly conventional analyses hard copy report received from GBRA laboratory >>>

QAO and Data Manager check GBRA data reports for completeness, holding times, mins, maxs,
             AWRLs, LOQs, etc. >>> numeric comparisons of field splits >>>

Data is hand entered into Access water quality database and flow and secchi disk data are added
                               to results from field notebook >>>

              Data entry is 100% checked by Data Manager and 10% by QAO >>>

Lab report originals are kept in LNRA permanent file vault and copies are kept in water quality
       department—data also stored on laserfiche in the LNRA network database >>>

Water quality Access database is backed up onto CD-rom – 1 copy stored in vault and 1 copy in
water quality department. In addition, data is saved on LNRA network in a dedicated file. >>>

   Three times annually data is submitted to TCEQ for inclusion in SWQMIS. Data Manager
exports period of record data from database and properly formats. QAO checks data file. Data
 then is e-mailed to Rocky Freund, Data Management and web page consultant at Nueces River
 Authority. Consultant checks data for mins, maxs, format, redundancies, matching event and
                                  results, tag numbers, etc. >>>

 Consultant sends recommendations to LNRA where any needed changes are made to both data
   submittal file and to Access database by Data Manager and 100% checked by QAO >>>

    Data (1 events file, 1 results file) is e-mailed to CRP Project Manager at TCEQ, and Data
                                 Summary hard copy is mailed. >>>

                    TCEQ sends LNRA any needed changes and revisions >>>

                   LNRA makes necessary revisions and returns to TCEQ >>>

                                   Data is added to SWQMIS >>>

 Consultant downloads data monthly from SWQMIS and adds to water quality database posted
                 on the LNRA web site. Data is then available to the public.
LNRA QAPP                                                                                                Page 34

Record Keeping and Data Storage

Field results data acquired with YSI multi-parameter probes are downloaded from datalogger into
EcoWatch software on a PC, and a hard copy is printed out and kept on file. Data is then hand-typed into
the Access water quality database, and other data, e.g. Secchi disk depth and flow, are added to the
electronic files from field notes. The forms used for field notes and for flow calculations appear in
Appendix C. Additionally, quarterly conventional sample results from the GBRA laboratory are sent to
LNRA in a hard-copy report format. Originals are kept in LNRA permanent files, and copies are kept in
CRP department files. These lab results are also stored in laserfiche in the LNRA network. This data also
is hand-typed into the Access water quality database.

Data Errors and Loss

After each sampling site has been entered into the LNRA Access water quality database, a hard copy of this
section is printed out and carefully checked for accuracy by the Data Manager. Three times annually this
data is converted into an ASCII text file, checked by QAO, and sent to a consultant at Nueces River
Authority (NRA) who reviews the data for format, exceedences in AWRLs, mins and maxs, LOQs, tag
redundancies, and numerical/clerical errors. The consultant sends the data back to the LNRA Data Manager
and QAO with any recommendations or corrections needing to be made. Once completed, the data is
electronically transferred to Cory Horan, CRP Project Manager at TCEQ in an ASCII text file format. A
hard copy of the Data Summary form (Appendix E) is mailed to TCEQ.


Data Handling, Hardware, and Software Requirements

The Authority utilizes an array of data gathering, processing, and output hardware. Data gathering for
monitoring and control operations utilizes field located instruments such as flow meters, precipitation
gages, and pressure transducers that are linked to the Authority’s main offices through radio transmitters.
LNRA utilizes YSI multi-parameter datasondes to gather field data. The data is hand-entered into field log
books, and the data is also downloaded into a PC from the datalogger, and hard copies are printed and kept
on file. Both field and conventional laboratory analyses results are entered into an Access water quality
database running on Windows XP platform. The Access water quality database is also backed up onto the
LNRA network system. The Access files are exported as ASCII text files for submittal to the TCEQ.
ESRI’s Arcview is the software used for the GIS database. The computers used by the LNRA CRP staff
have internet access in order to facilitate transmission of data and information to and from TCEQ via
electronic mail.
The Clean Rivers Program grantees (including LNRA) do not create data using Global Positioning System
(GPS) equipment. GPS equipment may be used as a component of the information required by the Station
Location (SLOC) request process, but TCEQ staff are responsible for creating the certified locational data
that will ultimately be entered into the TCEQ’s Surface Water Quality Monitoring database. Any
information developed by Clean Rivers Program grantees using a Geographic Information System (GIS)
will be used solely to meet deliverable requirements and will not be submitted to the TCEQ as a certified
data set. Because the Clean Rivers Program grantees do not create certified locational data, TCEQ OPP
8.11 (Surface Water Quality Monitoring Data Management Reference Guide, GIS Policy) and TCEQ OPP
8.12 (GPS Policy) do not apply.

Information Resource Management Requirements

Backup/Disaster Recovery – Data compiled via sampling and monitoring are backed up onto compact
discs. One copy is kept in CRP department files, and one copy in the LNRA vault. Data is also stored on
the LNRA network in a dedicated file. Hard copy of this data is also always available in case of system
failure. Full data recovery could be accomplished within one to two work weeks. Additionally, historic and
TCEQ-approved water quality data for the Lavaca Basin is stored off-site in a dedicated server by the
Nueces River Authority consultants. This data can be accessed on-line by both LNRA and the public.

TCEQ-approved Lavaca Basin Water Quality data is available to the public via the LNRA web site @
http://www.LNRA.org. From the home page one can choose the “Water Quality Program” page from the
“Education and Programs “pull-down menu and then choose “Water Quality Data” from the top of list on
that page. This will connect the user to the remote dedicated server maintained by the Nueces River
Authority. This server contains the historic database of all existing water quality data for the Lavaca Basin,
as well as current data which has been TCEQ-approved, and this site is updated monthly with any changes
in the state SWQMIS water quality database. The public can query this database by county, by site
number, by Segment number, or by parameter via a pull-down menu of parameters (with storet codes)
provided on the web site. When one queries by county name or by Segment number, a list appears which
gives a description and location of each site in the county or Segment with the SWQM (Surface Water
Quality Monitoring) site number. Once a site number is chosen a list of all available data by date appears,
and at this point one may query by either date or parameter (storet code) number. Also under “Water
Quality” on the web site are a Lavaca Basin monitoring schedule, a map of current monitoring sites, and a
link to the State on-line Coordinated Monitoring Schedule.

The public is also welcome to contact LNRA for water quality data of interest to them, and LNRA will
provide the data or will provide assistance with navigating through the LNRA web site to obtain data. The
public is invited to the annual Basin-wide Steering Committee Meeting where a review of recent water
quality data and an explanation of current and future water monitoring activities are presented.

Archives/Data Retention - Complete original data sets are archived on permanent media in hard copy and
retained on-site by the LNRA for a retention period specified in the current QAPP. Each data set submitted
to the TCEQ is backed up on either diskette or CD-ROM (depending on size of file) and kept perpetually
on file. In addition, each set of water quality data submitted to TCEQ is stored on the QAO’s computer
hard drive.

Corrective Action

The LNRA QAO is responsible for implementing and tracking corrective action resulting from audit
findings outlined in the audit report. Records of audit findings and corrective actions are maintained by
both the CRP and the LNRA QAO. Audit reports and corrective action documentation will be submitted to
the TCEQ with the Progress Report.

If audit findings and corrective actions cannot be resolved, then the authority and responsibility for
terminating work are specified in the CRP QMP and in agreements in contracts between participating
organizations.

D1      DATA REVIEW, VERIFICATION, AND VALIDATION

Note: For the purposes of this document, the term verification refers to the data review processes used to
determine data completeness, correctness, and compliance with technical specifications contained in
applicable documents (e.g. QAPPs, SOPs, QMs, analytical methods). Validation refers to a specific
review process that extends the evaluation of a data set beyond method and procedural compliance (i.e.,
data verification) to determine the quality of a data set specific to its intended use.

All field and laboratory will be reviewed and verified for integrity and continuity, reasonableness, and
conformance to project requirements, and then validated against the project objectives and measurement
performance specifications which are listed in Section A7. Only those data which are supported by
appropriate quality control data and meet the measurement performance specifications defined for this
project will be considered acceptable, and will be reported for entry into SWQMIS.

D2      VERIFICATION AND VALIDATION METHODS

All field and laboratory data will be reviewed, verified and validated to ensure they conform to project
specifications and meet the conditions of end use as described in Section A7 of this document.

Data review, verification, and validation will be performed using self-assessments and peer and
management review as appropriate to the project task. The data review tasks to be performed by field and
laboratory staff are listed in the first two sections of Table D2, respectively. Potential errors are identified
by examination of documentation and by manual examination of corollary or unreasonable data. If a
question arises or an error is identified, the manager of the task responsible for generating the data is
contacted to resolve the issue. Issues which can be corrected are corrected and documented. If an issue
cannot be corrected, the task manager consults with higher level project management to establish the
appropriate course of action, or the data associated with the issue are rejected. Field and laboratory
reviews, verifications, and validations are documented.

After the field and laboratory data are reviewed, another level of review is performed once the data are
combined into a data set. This review step as specified in Table D2 is performed by the LNRA Data
Manager and QAO and a consultant. Data review, verification, and validation tasks to be performed on the
data set include, but are not limited to, the confirmation of laboratory and field data review, evaluation of
field QC results, additional evaluation of anomalies and outliers, analysis of sampling and analytical gaps,
and confirmation that all parameters and sampling sites are included in the QAPP.

Another element of the data validation process is consideration of any findings identified during the
monitoring systems audit conducted by the TCEQ CRP Lead Quality Assurance Specialist. Any issues
requiring corrective action must be addressed, and the potential impact of these issues on previously
collected data will be assessed. After the data are reviewed and documented, the LNRA QAO validates
that the data meet the data quality objectives of the project and are suitable for reporting to TCEQ.

If any requirements or specifications of the CRP are not met, based on any part of the data review, the
responsible party should document the nonconforming activities and submit the information to the LNRA
Data Manager with the data. This information is communicated to the TCEQ by the LNRA in the Data
Summary.

       TASK 3:         WATER QUALITY MONITORING

Objectives:    Water quality monitoring will focus on collecting information to characterize water quality in a variety
               of locations and conditions. These efforts will include a combination of:

                  planning and coordinating basin-wide monitoring
                  routine, regularly-scheduled monitoring to collect long-term information and support statewide
                   assessment of water quality
                  systematic, regularly-scheduled short-term monitoring to screen water bodies for issues
                  permit support monitoring to provide information for setting permit effluent limits
                  special study, intensive monitoring targeted to:
                   o identify sources and causes
                   o assess priority water quality issues
                   o obtain background water quality information
                   o provide information for setting site-specific permit effluent limits
                   o evaluate & develop statewide, regional, and site-specific water quality standards

Task
Description:   Monitoring Description
               LNRA plans to monitor at a total of 22 sites:
                   18 sites will be monitored monthly for field data
                   17 sites quarterly for laboratory conventional parameters
                   6 reservoir sites for chlorophyll-a quarterly
                   8 sites for E. coli bacteria quarterly

               In addition LNRA contracts with United States Geological Survey for water gages and:
                    6 sites for metals (USGS)
                    8 sites for organics (pesticides and herbicides) (USGS)
                   This USGS contracted monitoring will not fall under the LNRA QAPP.

               All other monitoring procedures and methods will follow the guidelines prescribed in the LNRA
               QAPP, the TCEQ Surface Water Quality Monitoring Procedures, Volume 1: Physical and Chemical
               Monitoring Methods for Water, Sediment, and Tissue (RG-415) and the TCEQ Surface Water
               Quality Monitoring Procedures, Volume 2: Methods for Collecting and Analyzing Biological
               Community and Habitat Data (RG-416).

               Coordinated Monitoring Meeting -- When deemed necessary by TCEQ, LNRA will hold an annual
               coordinated monitoring meeting. Qualified monitoring organizations will be invited to attend the
               working meeting in which monitoring needs and purposes will be discussed segment by segment
               and station by station. Information from participants and stakeholders will be used to select stations
               and parameters that will enhance overall water quality monitoring coverage, eliminate duplication of
               effort, and address basin priorities. The changes to the monitoring schedule will be entered into the
               statewide database on the Internet (http://cms.lcra.org) and communicated to meeting attendees.
               Changes to monitoring that occur during the course of the year will be entered into the statewide
               database on the Internet and communicated to meeting attendees.

               Progress Report
               Each Progress Report will indicate the number of sampling events and the types of monitoring
               conducted in the quarter, to include all types of monitoring.




Equipment:     No new equipment will be purchased with CRP funds to accomplish the work in this task.

Appendix B Sampling Process Design and Monitoring Schedule (plan)

Sample Design Rationale

The sample design is based on the legislative intent of the Clean Rivers Program. Under the legislation, the
Basin Planning Agencies have been tasked with providing data to characterize water quality conditions in
support of the 305(b) assessment, and to identify significant long-term water quality trends. Based on
Steering Committee input, achievable water quality objectives and priorities and the identification of water
quality issues are used to develop work plans which are in accord with available resources. As part of the
Steering Committee process, the LNRA coordinates closely with the TCEQ and other participants to ensure
a comprehensive water monitoring strategy within the watershed.

Based on input obtained during the Steering Committee Meetings, LNRA has formulated the FY 2008
Monitoring Schedule. LNRA intends to cover the Lavaca Basin as thoroughly as possible (within resource
limits) during current and planned monitoring for FY 2008. LNRA will continue its intense routine
monitoring activities in and near Lake Texana and in the inflows to the Lake: Navidad River, Sandy
Creek, and East and West Mustang Creeks. LNRA will also monitor and sample in the Lavaca River in
Segment 1602 (above tidal influence) at 3 sites and at Rocky Creek (receiving water for Shiner WWTP
effluent). LNRA will monitor below the Palmetto Bend Dam in Segment 1603, and along the tidally
influenced Segment 1601 of the Lavaca River below its confluence with the Navidad River and southward
on to near the mouth of Lavaca Bay.

Site Selection Criteria

This data collection effort involves monitoring routine water quality, using procedures that are consistent
with the TCEQ SWQM program, for the purpose of data entry into the statewide database maintained by
the TCEQ. To this end, some general guidelines are followed when selecting sampling sites, as basically
outlined below, and discussed thoroughly in the TCEQ Surface Water Quality Monitoring Procedures,
Volume 1 (RG-415). Overall consideration is given to accessibility and safety. All monitoring activities
have been developed in coordination with the CRP Steering Committee and with the TCEQ.

1.     Locate stream sites so that samples can be safely collected from the centroid of flow. Centroid is
       defined as the midpoint of that portion of stream width which contains 50 percent of the total flow.
       If few sites are available for a stream segment, choose one that would best represent the water
       body, and not an unusual condition or contaminant source. Avoid backwater areas or eddies when
       selecting a stream site.

2.     At a minimum for reservoirs, locate sites near the dam (reservoirs) and in the major arms. Larger
       reservoirs might also include stations in the middle and upper (riverine) areas. Select sites that best
       represent the water body by avoiding coves and back water areas. A single monitoring site is
       considered representative of 25 percent of the total reservoir acres, but not more than 5,120 acres.

3.     Routine monitoring sites are selected to maximize stream coverage or basin coverage. Very long
       segments may require more stations. As a rule of thumb, stream segments between 25 and 50 miles
       long require two stations, and longer than 50 miles require three or more depending on the
       existence of areas with significantly different sources of contamination or potential water quality

LNRA QAPP                                                                                                   Page 46
                                                                            4ae06a32-7fd7-469b-9991-006168c78019.doc
       concerns. Major hydrological features, such as the confluence of a major tributary or an instream
       dam, may also limit the spatial extent of an assessment based on one station.

4.     Because historical water quality data can be very useful in assessing use attainment or impairment,
       it may be best to use sites that are on current or past monitoring schedules.

5.     All classified segments (including reservoirs) should have at least one routine monitoring site that
       adequately characterizes the water body., and should be coordinated with the TCEQ or other
       qualified monitoring entities reporting routine data to TCEQ.

6.     Routine monitoring sites may be selected to bracket sources of pollution, influence of tributaries,
       changes in land uses, and hydrological modifications.

7.     Sites should be accessible. When possible, stream sites should have a USGS or IBWC stream flow
       gauge. If not, it should be possible to conduct flow measurement during routine visits.
