Description:

Abstract:

Wellhead Protection Area (WHPA) is the Minnesota Department of Health (MDH) approved surface and subsurface area surrounding a public water supply well or well field that supplies a public water system, through which contaminants are likely to move toward and reach the well or well field.

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).
