WA234 - Non-Potable Ground Water In Washington - Completed FY1982
Problem - The Safe Drinking Water Act requires EPA to develop minimum requirements for State programs to protect underground drinking-water resources. Part C of the Act, "Protection of Underground Sources of Drinking Water," allows each State to develop an enforceable underground injection control (UIC) program, for EPA approval. The agency responsible for development of such a program for Washington State is the Department of Ecology (DOE). To develop a UIC program, DOE needs an inventory of the aquifers in the State which contain non-potable water, and the probable cause of this non-potability.
Objectives - To assemble existing ground-water quality data to delineate those portions of the major aquifers in the State which contain non-potable water. The criteria by which this evaluation will be made will essentially be an evaluation of dissolved-solids concentration, fluoride, and nitrate.
