POWERPOINT PRESENTATION
NEGAUNEE TOWNSHIP
Drinking Water Protection Plan
The Negaunee Township Wellhead
Protection Committee is committed to
bringing you (the public) safe drinking
water now and in the future. It is hoped
that through this presentation, we can
inform you of how you can help to keep our
drinking water safe. Thank You.
Committee Members: Wellhead protection is a process
  1. Bill Carlson  of identifying and protecting the
  2. Jim Derocher  area of land near the drinking
  3. Carl Nurmi    water wells (the "wellhead") from
  4. Jim Thams     potential hazards. Contamination
  5. Mike Turino   in the wellhead area could affect
  6. Mike Adams    your water supply years into the
  7. Joe Scanlan   future.
This Presentation focuses on the following areas:
(with emphasis on Contaminant Evidence, Causes,
and Prevention)

1.   Abandoned Wells
2.   Failing or Poorly Located Septic Systems
3.   Household and Garden Chemicals
4.   Improper Disposal of Contaminants
         Abandoned Wells
      There can be a direct pathway for
  contaminants to enter groundwater where
 there are numerous old or abandoned wells
 throughout our Wellhead Protection Areas.
Abandoned wells can also be an extreme safety
   hazard, especially for children. Potential
contaminants range from lawn fertilizers and
          pesticides to animal waste.
Contaminant Evidence
1. Detection of high bacteria levels in well water tests.
2. Well water turbidity.
3. Detection of other contaminants in well water.

Causes
1. Old well casing or leaky casings.
2. Well cover not watertight
3. Open abandoned wells.
4. Groundwater movement from contaminated to
uncontaminated wells.

Prevention
1. Watertight well cover.
2. Tight well casing.
3. Tight plumbing connections.
4. Identify and seal open abandoned wells.
Failing or Poorly Located Septic Systems

A septic system is just that…a system. It needs
  to be properly installed and maintained to
    function properly. Many homes in the
    Wellhead Protection Area have a septic
system. Here are some “do’s” and “don’ts” to
  follow in order to keep your septic system
             functioning properly.
Contaminant Evidence
1. Wastewater shows above ground.
2. Detection of excessive bacteria, chemical in well water tests.
3. A system that is failing is showing no obvious signs without
inspection.
Causes
1. Poor installation or maintenance.
2. Disposal of household chemicals such as paint thinners into the
system.
3. Overloading the system with a garbage disposal unit.
4. Use of septic tank cleaning additives.
5. Too many closely-spaced septic systems in a limited area.
Prevention
1. Proper installation.
2. Inspection and cleaning by septic cleaning services every 2 to 4
years, annually if garbage disposal is used.
3. Do not dispose of household chemicals into the system.
  House and Garden Chemicals
Contaminant Evidence
1. Detection of chemicals in well water tests.
Causes
1. Improper use and storage.
2. Improper disposal in backyard, ditches, low ground, septic
systems, and overgrown areas.
Prevention
1. Proper use.
2. Public information / education.
3. Provide local disposal facilities for unused chemicals and
chemical containers.
4. Encourage use of less hazardous products.
Improper Disposal of Contaminants
      One of the most common forms of
   groundwater contamination is improper
 disposal of household contaminants ranging
 from used motor oil to paint. A number of
 local businesses and agencies either recycle
  or can properly dispose of your household
  contaminants. For more information call:
    Rick Aho at Marquette County Waste
    Management Authority, 906-249-4125.
Contaminant Evidence
1. Petroleum odor in well water.
2. Other chemical odors.
3. Detection of chemicals in well water tests.

Causes
1. Improper disposal of chemicals, oil, pesticides, other wastes and
used containers.

Prevention
1. Public information / education.
2. Disposal facilities for small hazardous wastes generators.
3. Enforcement against improper waste disposal.
4. Recycle used motor oil.
     Map of Wellhead Protection Area
   The map on the next slide represents the Negaunee
   Township Wellhead Protection Area (Township 48
  North, Range 26 West, Sections 26, 27, 34, and 35).
  In groundwater systems, contaminants may move at
different rates than the groundwater, depending on the
 specific characteristics of the contaminant. Typically,
    contaminants move at rates much slower than the
  groundwater flow rate. Contaminants released at the
 grounds surface also travel vertically which may take
   longer to reach the actual groundwater depth. It is
   highly unlikely that potential contaminant sources
located outside of this map could cause a water quality
                         impact.
