Originator:Minnesota Department of Natural Resources

Title: Hubbard County Groundwater Atlas, Part B

Abstract: ArcGIS files depicting characteristics of the groundwater system of Hubbard County, Minnesota.

Purpose: Geographic information system (GIS) layers cartographically depict spatially analyzed data used in the production of the Hubbard County Groundwater Atlas, Part B, County Atlas Series C-41.

A county atlas is a systematic study of a county's geologic and groundwater resources. Geologic studies include glacial deposits. Groundwater studies include the distribution of surficial and buried aquifers; hydrogeology of the surficial and buried sand and gravel aquifers; estimation of groundwater residence time; and sensitivity to pollution of the buried sand and gravel aquifers and the near-surface materials.

Lineage: Review and compile available data:
Many of the figures and maps produced for County Groundwater Atlas, Part B are generated using GIS data produced for Part A by Minnesota Geological Survey (MGS) staff. Other sources of information include historical chemistry data stored in the Environmental Quality Information System (EQuIS) maintained by the Minnesota Pollution Control Agency, historical chemistry data from the Minnesota Department of Health, water use information available in the Minnesota Permitting and Reporting System (MPARS), and water well information from the County Well Index (CWI) database maintained jointly by the MGS and the Minnesota Department of Health. The basemap files in base.gdb were obtained from files available through the Geospatial Commons (County Boundaries, Minnesota and DNR Hydrography Dataset) and from Part A.

Collection of data from the field:
Samples of groundwater from select wells completed in various aquifers were collected for chemical analysis. Additional samples were collected from surface water. This water chemistry information, combined with water level data from CWI and GIS data from Hubbard County Geologic Atlas, Part A were used to create groundwater flow maps, pollution sensitivity maps, cross sections, and other maps and figures.

Creation of GIS layers:
Using a variety of techniques, data are converted into ArcGIS feature classes or grids for cartographic display and spatial analysis. Metadata for individual layers contain more detailed lineage information.
