What is the Wellhead Protection Area?
A Wellhead Protection Area (WHPA) is a geographically designated 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. This is an area where groundwater protection is emphasized. A WHPA includes at least the delineated capture zone area, but could be influenced by other factors such as existing land use and zoning, site and facility identification and location, political boundaries, natural features, and environmentally sensitive areas.
