SOURCES OF DRINKING WATER

  • Wisconsin has nearly 11,500 public water systems which meet the daily water needs of about 4 million people. Public water systems that are owned by a community are called municipal water systems. Shawano County has 10 municipal water systems.  Table showing water systems in Shawano County
 

GROUNDWATER PROTECTION POLICIES   Table showing water systems in Shawano County

  • 5 of 10 municipal water systems in Shawano County have a wellhead protection plan: Bowler, Gresham, Mattoon, Shawano Lake Sanitary District and Shawano.
  • 3 of 10 municipal water systems in Shawano County have a wellhead protection ordinance: Gresham, Mattoon and Shawano.
  • Shawano County has adopted an animal waste management ordinance.
 

MONEY SPENT ON CLEANUP

  • Over $14 million has been spent on petroleum cleanup in Shawano County from leaking underground storage tanks, which equates to $362 per county resident.
  • 1 municipal water system in Shawano County has spent money to reduce nitrate levels.
 

GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Shawano County has increased from about 6.6 million gallons per day to about 8.5 million gallons per day.*
  • The increase in total water use over this period is due to a increase in industrial use.
  • The proportion of county water use supplied by groundwater has decreased from about 83% to 61% during the period 1979 to 2005.*
  • Water use in Wisconsin is generally estimated for the following categories:
    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses
    • Thermoelectric or mining*

* Thermoelectric and mining data are not considered in water-use tables or figures on this web site. Thermoelectric-power water use is the amount of water used in the process of generating thermoelectric power. The predominant use of water is as non-contact cooling water to condense the steam created to turn the turbines and generate electricity.

 

SUSCEPTIBILITY OF GROUNDWATER TO CONTAMINANTS   Susceptibility map

  • Wisconsin has abundant quantities of high-quality groundwater, but once groundwater is contaminated, it's very expensive and often not technically possible to clean.
  • An evaluation of the susceptibility of groundwater to contamination in Shawano County can be seen in the FULL REPORT or accessed through the map link above.
 

GROUNDWATER QUALITY

  • 92% of 211 private well samples collected in Shawano County from 1990-2006 met the health-based drinking water limit for nitrate-nitrogen.   Nitrate map
  • A 2002 study estimated that 18% of private drinking water wells in the region of Wisconsin that includes Shawano County contained a detectable level of an herbicide or herbicide metabolite. Pesticides occur in groundwater more commonly in agricultural regions, but can occur anywhere pesticides are stored or applied.   Statewide pesticide map
