By: J. Wallace and M. Lowe Nitrate from sewers, septic-tank-soil-absorption systems, fertilizer, and other anthropogenic sources is a useful indicator of human impact on ground-water quality. Nitrate can thus be used to identify potential deleterious effects of development which uses septic tank soil-absorption systems. The purpose of this document is to: (1) provide a valley-wide assessment of the potential impact of nitrate from increasing the number of septic tank soil-absorption systems on ground water in Tooele Valley using methods similar to those used by Hansen, Allen, and Luce, Inc. for Heber and Round Valleys, Wasatch County, Utah; and (2) provide site-specific recommendations for evaluating the effects of septic systems on ground-water quality for proposed subdivisions in Tooele Valley.
