Effects of On-site Sewage Disposal Facilities on Ground Water Within the Wood River Valley

Abstract

Quality of well water is an indicator of ground water quality. Chloride and nitrate-N concentrations, from May to December of 1991, were determined in water samples obtained from 48 different wells, located in four different hydrologic areas of the Wood River Valley. Results of the first set of these tests were contrasted to a previous study. The comparison indicates no degradation of ground water quality has occurred since 1982. The second set of tests studied three other areas near the Wood River. These tests provided information about ground water in these areas and will create base-line data for further studies.
