Wellhead Protection
The Wellhead Protection Program is a pollution prevention and management program used to protect underground based sources of drinking water. The federal Safe Drinking Water Act (SDWA), as amended in 1986, established a program for the states to delineate and manage Wellhead Protection Areas (WHPAs) for protection of ground water supplies from contamination. A Wellhead Protection Area is defined as the surface and subsurface area surrounding a public water supply well, through which contaminants are reasonably likely to move toward and reach the well.
