Source Water Assessment and Protection Program

Source Water Assessment Approach

 

Source water assessment were completed for each of the approximately 760 public water supply systems operating in South Dakota (in 2000-2003) . A complete assessment is a three-step process that includes:

 

1.  delineating the part of the watershed or ground water area that contributes water to the water supply;
2.  identifying the significant potential sources of drinking water contamination in those areas;
3.  determining the water supply's susceptibility to contamination from those sources.
