Extent of available data.
This data layer indicates the vulnerability of Drinking Water Supply Management Areas. It was developed by the Minnesota Department of Health. Drinking Water Supply Management Areas surround public wells. They encompass Wellhead Protection Areas and have boundaries that have been aligned with roads, landmarks, and administrative boundaries for ease of identification. They are managed to ensure a safe and reliable source of drinking water. The vulnerability of these areas and sub-divisions of these areas can give guidance to management plans that best protect the resource.
