EPA MODELING TOOLS FOR CAPTURE ZONE DELINEATION
Citation:
KRAEMER, S. R. AND H. M. HAITJEMA. EPA MODELING TOOLS FOR CAPTURE ZONE DELINEATION. Presented at National Ground Water Association Ground Water Expo, Marietta, GA, December 13 - 16, 2005.
Impact/Purpose:
The objective of this project is to develop computer tools to delineate the zone contributing recharge to public water supply wells, and thus, support State, Tribes, and communities toward best management practices as they revisit current delineations, and design wellhead protection areas for new wells.
Description:
The EPA Office of Research and Development supports a step-wise modeling approach for design of wellhead protection areas for water supply wells. A web-based WellHEDSS (wellhead decision support system) is under development for determining when simple capture zones (e.g., centric circular, eccentric circular, boat-shaped) would be protective given limited available data. The presentation will also discuss when full-featured professional modeling tools and additional data collection is appropriate.
