Abstract The Asotin County (Washington) Public Utility District petitioned the Environmental Protection Agency (EPA) to declare its drinking water supply as a sole source aquifer under Section 1424(e) of the Safe Drinking Water Act. In response, EPA prepared a document which briefly describes the geology, ground-water hydrology, and drinking water consumption of the Lewiston Basin. The report describes the technical basis for EPA's decision to designate the Lewiston Basin Aquifer System as a sole source aquifer. The Lewiston Basin is an approximately 500 square mile structural and topographic depression in southeastern Washington and western north-central Idaho, including part of the Nez Perce Indian Reservation. Ground water provides about 68 percent of the drinking water consumed in the Lewiston Basin. Community water supply wells all withdraw drinking water from the Grande Ronde Basalt. However, according to EPA guidelines, those supplies cannot economically serve all those who depend upon the aquifer system for drinking water.
