The 1986 Amendments to the United States Safe Drinking Water Act (SDWA) made wellhead protection an important issue for water suppliers in the US.
These Amendments mandate that each State develop a wellhead protection program (WHPP) to protect the wellhead areas of all public water systems from contaminants that may have adverse human health effects.
Data requirements to support a WHPP can become unwieldy without the benefit of a system that can handle large databases involving spatial relationships.
Geographic information systems (GIS) store, analyse, map and illustrate data sets of complex spatial information, and can therefore be used to integrate and analyse various types of spatial data needed to delineate wellhead protection areas.
The Cheyenne-Arapaho tribe has initiated a study of the groundwater resources on the Concho Reserve in Canadian County, Oklahoma, US.
Groundwater within the Concho Researve is vulnerable to contamination because of the high permeability of the alluvial aquifer associated with the North Canadian River.
Pollutants of concern are associated with industrial agricultural and domestic sources in the recharge area.
This paper describes the development of an interface allowing the Cheyenne-Arapaho tribe to delineate and manage wellhead protection areas (WHPAs).
The system described herein provides for two modes of operation. (...)
