Implementation of a wellhead protection program utilizing a geographic information system
Hendricks, Laurel Ann
Master of Science
The purpose of this research was development of a geographic information system (GIS) and linkage with existing ground-water models to expedite wellhead protection area (WHPA) delineation within a wellhead protection (WHP) program. Research objectives included: (1) incorporation of relevant data from federal, state, and local agencies into the database; (2) delineation of WHPAs utilizing linkage established at Rice University between the GIS and WHPA (a ground-water model which delineates capture zones); (3) evaluation of model input parameter sensitivities to address effects of parameter input on the shape of delineated WHPAs; (4) demonstration of the utility of the GIS to facilitate WHPA delineation; and (5) development of a prototype ground-water management system. Harris County, Texas, already identified as a critical ground-water supply area, was selected as the project area. Public water well data on 224 City of Houston wells served as the initial dataset for the development of a county-wide WHP program.
