Products include maps and interpretive reports of geology, groundwater, pollution sensitivity, and special studies. Many provide separate GIS files and water chemistry information.
 | County Geologic Atlas (CGA)County by county geologic and groundwater information. Part A: Geologic studies include surficial deposits and bedrock. Part B: Groundwater studies include flow systems, aquifers, groundwater chemistry, and sensitivity to pollution. Early atlases were not split into two parts. |
 | Minnesota Hydrogeology Atlas (MHA)Extends maps, reports, and data originally published in the CGA program to new statewide coverage. |
 | Regional Hydrogeologic Assessment (RHA)Larger areas (typically 4-9 counties) covered in less detail than a County Geologic Atlas. These older assessments will be replaced by the County Geologic Atlases as they are completed. |
