Groundwater Capture Area

The “capture zone” is the proposed capture area within the aquifer. When there isn't a surface water contribution, the groundwater capture area is identical to the wellhead protection zone. When a conjunctive delineation is used, the groundwater capture area (GWCA – same as “capture zone’) and the surface water contribution area ( SWCA) are combined to form the wellhead protection area (WHPA).
