Aquatic Rational Threshold Value (RTV) Concepts for Army Environmental Impact Assessment.

Abstract

This report presents the results of a study undertaken to develop practical techniques for evaluating the 'significance' of predicted water quality impacts. Issues concerning the definition and use of the term 'significant' are discussed at length. Existing aquatic ecosystem models are reviewed, potential criteria for measuring significance are examined, and a concept framework is presented. The result is a Rational Threshold Value (RTV) concept for measuring the significance of impacts on aquatic features. Initial development of an aquatic RTV involves determination of toxicity levels resulting from the introduction of pollutants into aquatic ecosystems, and expression of the effects of these toxicants on population levels of selected fish species.
