The Minnesota Groundwater Contamination Atlas GIS data allows users to view groundwater areas of concern for sites in remediation programs. The data does not map areas of risk to the health of the communities. If there are potential health risks associated with a groundwater area of concern, proper remediation treatments or activities are implemented to protect human health.The six different layers in the geodatabase work together to represent what is shown on the site story maps in the Atlas. MPCA hydrogeologists reviewed many reports and data files, then used geographic information systems technology and professional judgment to map these areas. The dashed and solid outlines for these mapped areas represent two different levels of certainty. The solid outline represents area of concern boundaries that are more certain, while the dashed outline represents area of concern boundaries that are less certain.The MN Groundwater Contamination Atlas geodatabase includes the following datasets:Cleanup SitesCleanup Sites - No CACleanup Well Result SumContamination Areas - PolygonsContamination Areas - LinesPotential Source Areas
