AbstractARCVIEW shapefiles depicting a variety of characteristics of the ground-water system of the Southern Red River Valley, Minnesota RHA study area.
PurposeGeographic information systems (GIS) layers were created to cartographically depict and spatially analyze data used in the production of the Southern Red River Valley, Minnesota RHA study area, Part B.

A Regional Hydrogeologic Assessment (RHA) is a systematic study of a multi-county region's  geologic and ground-water resources. Geologic studies focus on  near-surface deposits. Ground-water studies include flow systems, aquifer capacity, ground-water chemistry, and sand and gravel deposits. Sensitivity of near ground-water systems is estimated.

The information is organized, analyzed, and displayed using GIS technology.

LineageReview of available data:
Investigations begin with a review of existing information, such as earlier geologic maps, soil maps, hydrologic reports, and information provided by well drillers. Drillers send water well logs to the Minnesota Geological Survey, where they are reviewed, interpreted, and entered into the County Well Index (CWI), an interactive data base of water-well information. 

Collection of data from the field:
Field studies are conducted to measure static water level elevations and chemistry of selected wells. These studies, combined with pre-existing data, are used to create models of water-table hydrogeology (elevation, potentiometric surface, potential yield, flow direction), and sensitivity of the near-surface ground water system to pollution.

Creation of GIS layers:
Using a variety of techniques, data is converted into Arc/INFO coverages or ARCVIEW shapefiles for cartographic display and spatial analysis.
