Source Water Protection Query System

The Source Water Protection Program (SWPP) Query System makes it easy to access source water assessment reports, plot a public water supply (PWS) on a map, or display information that exists in an area surrounding a PWS well. More than twenty data sets can be accessed through the SWPP Query System. The system was originally developed to help evaluate each PWS's susceptibility to potential contaminant sources. However, it is a useful tool for displaying information that can help answer a wide range of questions related to land and water resources.
