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 of
  identifying and protecting the area of land near
  the drinking water wells (the "wellhead") from
  potential hazards. Contamination in the wellhead
  area could affect your water supply years into
  the future.

• This Presentation focuses on the following areas
• (with emphasis on Contaminant Evidence, Causes,
• and Prevention)
• Abandoned Wells
• Failing or Poorly Located Septic Systems
• Household and Garden Chemicals
• 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 Evidence1. Detection of high
bacteria levels in well water tests.2. Well
water turbidity.3. Detection of other
contaminants in well water.Causes1. Old well
casing or leaky casings.2. Well cover not
watertight3. Open abandoned wells.4.
Groundwater movement from contaminated to
uncontaminated wells.Prevention1.
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 thata 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 dos and donts to follow in order to
  keep your septic system functioning properly.

12
Contaminant Evidence1. 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.Causes1. 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.Prevention1. 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.
13
House and Garden Chemicals

• Contaminant Evidence1. Detection of chemicals in
  well water tests.Causes1. Improper use and
  storage.
• 2. Improper disposal in backyard, ditches, low
  ground, septic systems, and overgrown areas.
• Prevention1. Proper use.
• 2. Public information / education.
• 3. Provide local disposal facilities for unused
  chemicals and chemical containers.
• 4. Encourage use of less hazardous products.

14
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.

15
Contaminant Evidence1. Petroleum odor in well
water.2. Other chemical odors.3. Detection of
chemicals in well water tests.Causes1.
Improper disposal of chemicals, oil, pesticides,
other wastes and used containers.Prevention1.
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.
