Wisconsin’s Source Water Assessment Program

As a result of the 1996 Amendments to the Safe Drinking Water Act, all states were required to complete source water assessments for all public water systems. DNR produced these assessments during the period between 1999 and 2003.

The assessments were provided to each public water system and included:

  1. a brief description of Wisconsin’s Source Water Assessment Program;
  2. a map of the system’s source water assessment area(s) and the potential contaminant sources within those area(s);
  3. a susceptibility determination based on presence of potential contaminant sources and other factors such as well construction, intake location and geology; and
  4. recommendations for source water protection.

Source water assessments are no longer available because the data they were based on is longer current.
