Title:
Drinking Water Supply Management Area Vulnerability
Abstract:
Drinking water supply management area (DWSMA) vulnerability is an assessment of the likelihood for a potential contaminant source within the drinking water supply management area to contaminate a public water supply well based on the aquifer's inherent geologic sensitivity; and the chemical and isotopic composition of the groundwater.
Purpose:
This dataset was developed with the intention of protecting the public drinking water supply and complies with the federal Safe Drinking Water Act, United States Code, title 42 and the State of Minnesota Rule (parts 4720.5100 to 4720.5590).
