Impact of Discharges as a Basis for Control Measures

Abstract

This paper develops a case for more studies to assess the impact of discharges upon receiving aquatic systems and thereby allow closer tailoring of control measures. General approaches for conducting such studies are described. One approach includes methodology to allow predictions of where in the environment a key effluent constituent will be transported, the rate and extent of its transformation, and its effect on organisms and environmental processes at expected ambient levels.
