Lineage

This is a polygon file showing the sensitivity to pollution of the Quaternary aquifer. The Quaternary sediment information is from the Wabasha CGA C14 Part A shapefile sgnt.shp (surficial geology polygons MGS Part A.). Sgnt.shp was joined in a union operation with the Wabasha CGA C14 Part A shapefile dtnt.shp (depth to bedrock), which indicates drift thickness. In the eastern Zumbro River valley and the entire Mississippi River valley, nearly all of the water wells are completed in Quaternary sand and gravel. The sensitivity ratings for wells completed in Quaternary sediment is generally higher than for wells completed in bedrock below thick Quaternary sections. The data were segregated into areas with less than 50 feet depth to bedrock and greater than 50 feet depth to bedrock. The Quaternary aquifer was defined as areas of sediment greater than 50 feet thick located in the Zumbro or Mississippi River Valleys. Areas were segregated based on the surficial geology polygons into areas with outwash or colluvium, and alluvium. The sensitivity ratings are Very High for outwash or colluvium, and High for alluvium.

Sensitivity interpretation was based on overlapping estimated time of travel ranges as follows:

Red - - Very High - - Hours to months
Orange - - High - - Weeks to years
Yellow - - Moderate - - Years to decades
Light green - - Low - - Decades to a century
Dark green - - Very Low - - A century or more
