SOURCE WATER PROTECTION OF PUBLIC DRINKING WATER WELLS: COMPUTER MODELING OF ZONES CONTRIBUTING RECHARGE TO PUMPING WELLS

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:

Computer technology to assist states, tribes, and clients in the design of wellhead and source water protection areas for public water supply wells is being developed through two distinct SubTasks: (Sub task 1) developing a web-based wellhead decision support system, WellHEDSS, to allow professionals without specialized training in ground-water flow modeling to responsibly use simple wellhead protection and assessment (WHPA) tools and make well founded decisions about the need to use more sophisticated computer modeling techniques; and (Sub task 2) making the EPA WhAEM2000 ground water modeling framework better, faster, and cheaper.

Project Information:

Progress :This is a new task. Past activities are documented in the WhAEM Progress Report 2004.

Relevance :

The research will support Safe Drinking Water Act activities of the EPA Office of Ground Water and Drinking Water and the Regions implement the Wellhead Protection Program and the Source Water Assessment Programs. The EPA WhAEM2000 software is used by States, Tribes, and water supply professionals for the delineation of wellhead protection zones. The application of the tool in the Charlotte, NC region will support the multi-partner SEQL (sustainability of environments for quality of life) project.
