Wellhead Protection Areas (WHPA)

EGLE’s source water protection program includes identification of areas where groundwater is used to supply drinking water to communities. A Wellhead Protection Area (WHPA) is the surface and subsurface area surrounding a water well or well field, supplying a public water system, through which contaminants are reasonably likely to move toward and reach such water well or well field. It is that area which contributes groundwater to a public water supply well.
