The Minnesota Department of Natural Resources has published the Washington County Groundwater Atlas. This Part B atlas covers groundwater conditions and sensitivity to pollution. It expands on Part A, the geology atlas previously published by the Minnesota Geological Survey.
The atlas can be used to help identify viable water sources, evaluate supply, identify recharge sources and flow, manage sustainability, guide decisions for well and septic system construction, assist in wellhead protection for public water supply and assess pollution sensitivity.
The atlas is available online and in printed form:
- Online: Washington County Groundwater Atlas. The webpage includes GIS files and PDFs of the report and maps. The GIS folder includes GIS files and associated metadata, as well as an ArcMap file that displays the data as shown on the published maps and includes hyperlinks to image files of the published cross sections. For Part A and other completed counties consult the County Atlas Status List.
- Paper copies: The geology and groundwater atlases can be purchased from Minnesota Geological Survey Map Sales, 612-626-2969. Prices for each atlas package range from $12–$15.
Partial funding for this project was provided by the Minnesota Environment and Natural Resources Trust Fund and the Clean Water Fund. For more information on the program, visit the County Groundwater Atlas website at mndnr.gov/groundwatermapping.
