 Annual Water Quality Report for 2008
The purpose of this report            is to provide you with information on the quality of the drinking water produced
by the St. Joseph Water Treatment Plant during the 2008 calendar year. The federal government established the
requirement for this Water Quality Report, more formally known as a Consumer Confidence Report, in 1998. We
welcome this opportunity to provide you with details of where your water comes from, what it contains, and how it
compares to Environmental Protection Agency (EPA) and Michigan Department of Environmental Quality (MDEQ)
Standards. In addition to the required information, this report includes articles to help keep you informed on current
and upcoming projects and the ongoing efforts by City of St. Joseph and Authority1 to meet the growing water demands
of the service area in the most economical manner possible. Questions regarding this report can be directed to Greg
Alimenti, Water Plant Superintendent.

Lake Michigan       is the source of the water for the St. Joseph Water Treatment Plant. The intake extends
approximately one quarter mile into the Lake. In 2004 a Source Water Assessment was conducted by the Michigan
Department of Environmental Quality using procedures established in the Great Lakes Protocol, Source Water
Assessment Program. The criteria were used to develop a “sensitivity” rating, which reflects the natural ability of our
source water area to provide protection against contamination of the water supply. A water source “susceptibility”

 New Water Agreement Enables Water Treatment Plant Improvements Plant
On April 21, 2009 at a special joint meeting of the Township Boards of Lincoln Charter
Township, Royalton Township, and St. Joseph Township; the City Commission of the City of
St. Joseph; and the boards of the Lake Michigan Shoreline Water and Sewage Treatment
Authority and the Southwestern Michigan Regional Sanitary Sewer and Water Authority,
the communities served by the St. Joseph Water Treatment Plant came together and
entered into a new 30-year agreement that will change the management structure of our
shared water systems and allow for important water system improvements.



At the heart of the agreement is the creation of a new joint operating board to supervise
the operation and maintenance of the water system and to establish water rates. The
newly established Water Service Joint Operating Board (WSJOB) will have voting
                                                                                             Above: Geotechnical survey rig conduct-

same base amount for water, although each community is able to establish additional
rates for system upgrades and replacement within its own jurisdiction. The City will
continue to own the plant and property.



This new management structure allowed all communities to feel comfortable entering into
a 30-year agreement, which in turn provides the necessary financial stability to allow the
water system to finance Water Treatment Plant improvements through the State of
Michigan Drinking Water Revolving Fund (DWRF). (Continued on page 5)

   Contaminants that may be present in source water include:
   •     Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic
         systems, agricultural livestock operations and wildlife.
   •     Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm
         water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
   •     Pesticides and herbicides, which may come from a variety of sources such as agriculture and residential uses.
   •     Radioactive contaminants, which are naturally occurring or the result of oil and gas production and mining activities.
   •     Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of
         industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and
         septic systems.

   In order to ensure tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in
   water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in
   bottled water which provide the same protection for public health. Many water suppliers add a disinfectant to drinking
   water to kill germs such as giardia and E. coli especially after heavy rainstorms. Your water system may add more
   disinfectant to guarantee that these germs are killed.



Terms and abbreviations used on the facing page
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or
expected risk to health. MCLGs allow for a margin of safety.
Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as
close to the MCLGs as feasible using the best available treatment technology.
Maximum Residual Disinfectant Level (MRDL): means the highest level of a disinfectant allowed in drinking water. There is
convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG): means the level of a drinking water disinfectant below which there is
no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial
contaminants.
N/A: Not applicable ND: not detectable at testing limit ppb: parts per billion or micrograms per liter ppm: parts per
million or milligrams per liter pCi/l: Picocuries per liter (a measure of radioactivity). Action Level (AL): The concentration of
a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.

* EPA considers 50 pCi/l to be the level of concern for beta particles.
** Unregulated contaminants are those for which EPA has not established drinking water standards. Monitoring helps EPA to determine
where certain contaminants occur and whether it needs to regulate those contaminants.

Water Quality Data
The table below lists all the drinking water contaminants that we detected during the 2008 calendar year. The presence of these
contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in
this table is from testing done January 1 – December 31, 2008. The State allows us to monitor for certain contaminants less than once per
year because the concentrations of these contaminants are not expected to vary significantly from year to year. All of the data is
representative of the water quality, but some are more than one year old. Chlorine, HAA5 and TTHM results are reported as “Running Annual
Averages” (RAAs).

       If present, elevated levels of lead can cause serious health problems especially for pregnant women and young children. Lead in drinking water is
       primarily from materials and components associated with water service lines and home plumbing. The City of St. Joseph Water Treatment Plant is
       responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has
       been sitting for several hours, you can minimize the potential lead exposure by flushing your tap 30 seconds to 2 minutes before using water for
       drinking or cooking. If you are concerned about lead in drinking water, testing methods, and steps you can take to minimize exposure, information is
       available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead

       Turbidity is a measure of the cloudiness of water. We monitor it because it is a good indicator of the effectiveness of our filtration system.
       Nephelometric Turbidity Units (NTU) is a measure of the clarity of water.

   *Total organic carbon (TOC) has no health effects. However, total organic carbon provides a medium for the formation of
   disinfection by-products. These by-products include trihalomethanes (THMs) and haloacetic acids (HAAs).
   Drinking water containing these by-products in excess of the MCL may lead to adverse
   health effects, liver or kidney problems, or nervous system effects, and may lead to an increased risk of getting cancer.
   There is nothing you need to do unless you have a severely compromised immune system, have an infant, or are
   elderly. These people may be at increased risk and should seek information from their health care providers. You do
   not need to boil your water or take other actions. If a situation arises where the water is no longer safe to drink, you will be
   notified within 24 hours.


   Upon learning about this violation, City Staff took immediate action to remedy the problem. In the short term, Water
   Treatment Plant Staff conducted specific tests to optimize the dose of coagulant delivered to the solids contacting
   clarifiers. Initial results indicated significantly improved TOC removal rates from this effort. Long term
   measures to correct this issue have been identified in the Drinking Water Revolving Fund (DWRF) Project Plan. These
   include construction of a new water intake into deeper Lake Michigan waters (where improved water quality is
   expected) and replacement of the solids contacting clarifiers with a flash mix process and plate settlers. Rehabilitation
   of the oldest bank of filters at the St. Joseph Water Treatment Plant is also included in the DWRF plan. While the short term
   measures are aimed at quickly returning the water to compliance requirements, the goal of the longer term plans
   is to exceed the requirements. Notification regarding this violation was sent to all St. Joseph customers in August 2008.

**Treatment Technique for TOC is based on the lowest running annual average of the monthly ratios of the % TOC removal achieved
to the % TOC removal required. A minimum ratio of 1.00 is required to meet the TT. The St. Joseph plant returned to compliance in
the 3rd and 4th Quarters by achieving ratios of 1.12 and a 1.37 respectively.

New Water Agreement (continued from page 1)

The timing of the agreement was critical to meet the state-mandated DWRF schedule. Approval was needed no later than May 5th to allow the
City to qualify for not only a low interest loan but also approximately 40% principal forgiveness through the federal American Recovery and
Reinvestment Act, often referred to as the Economic Stimulus Package, which is expected to reduce the cost of the project by more than $4
million.



Long-time residents will recall that the first water contract between the communities was regularly a source of conflict, so much so that it took
5 ½ years to negotiate a replacement contract, which took effect in 2003. The key to the success of the 2003 contract was the formation of
the Contract Implementation Committee (CIC), which provided a regular mechanism for the City and Authority municipalities to communicate
water related issues, set standards and perhaps most importantly, establish a level of trust and cooperation. When it became apparent that a
new water intake was necessary and that a longer-term agreement than the 2003 contract would be necessary to allow area residents to take
advantage of low-interest loans and to keep water rates as low as possible, members of the CIC provided the foundation for the discussion

team created to establish the terms of the new water service agreement. Indeed, the level of trust was such that the new water agreement
was crafted within 6 months of community leaders agreeing to explore the concept, and in only 4 months of regular discussions. We would like
to thank the members of the discussion group—Chuck Garlanger, John Hodgson, Robert Judd, Deb Koroch, Ray Mak, Al Pscholka, Steve Tilly,
Frank Walsh and Tim Zebell—for their work, and to thank the governing bodies of the municipalities and boards involved for their willingness to
work together on behalf of the entire community.

Authority Water Towers are Online, Filled and In-Service!
After much anticipation, the two towers maintained and operated by the Southwest Michigan Regional Sanitary Sewer and Water Authority
are just that…in operation! Beginning on June 3, 2009, the City of St. Joseph has been utilizing the new booster stations to maintain water
levels in the new towers that result in increased pressures in the Authority service area. To guage the results of the project, Authority
officials have been monitoring and measuring pressures at numerous locations in the highly elevated areas of Stevensville. The findings of
this monitoring reaffirmed the expected outcome of the project. Pressures in the Stevensville area were found to range between 40-50 psi,
a substantial increase from the previous 20-35 psi. Many property owners have even commented to officials about the improvements in
pressure, which is always gratifying to those involved in the implementation of the project.



The towers, located along Jericho Road in Lincoln Charter Township and Miners Road in Royalton Township, require only a few restoration
items and final touch-ups to be considered complete. Thereafter, the towers will serve the member municipalities for years to come.



In a time when a lack of public infrastructure investment is creating significant hardships and shortfalls in other communities throughout the
country, the Authority is proud to implement a project to sustain a safe and reliable water supply which is critical to the future prosperity of
the area.

rating was then established based upon the sensitivity rating coupled with other factors that affect whether a contaminant reaches the
intake. Surface source sensitivity and susceptibility ratings range from moderate sensitivity/moderately low susceptibility to very high
sensitivity/very high susceptibility. The conclusion of the assessment indicated the Lake Michigan water used by the St. Joseph Water
Treatment Plant is considered highly sensitive and highly susceptible to potential contamination but the report also stated the “City of St.
Joseph Water Treatment Plant has effectively treated this source water to meet drinking water standards.” A copy of the Source Water
Assessment Report is available at St. Joseph City Hall, in the City Engineer’s office.
