Use of Whpa and Drastic Models in Vulnerability Assessment of Aquifers on a Gis Platform
Abstract
This research uses the EPA developed wellhead protection area (WHPA) model, to delineate the wellhead protection area for different times of travel through the major aquifers surrounding Enid, Oklahoma. The methodology involves the tracking of flow movement within the aquifers for 30 years in different well fields. Furthermore, this research involves the integration of the output from the WHPA model to a GIS platform. This research also uses the DRASTIC model of the EPA to evaluate vulnerability of aquifers from nitrate contamination, resulting from agricultural activities. This model also is integrated on to a GIS platform. Other potential sources of contamination include oil and gas wells and hazardous waste sites and municipal landfills in the Enid area.
