Abstract

This paper addresses the problem of planning the construction and expansion of a sewage treatment facility operating on a river. It is argued that any model for solution of the problem must take explicit account of the many uncertainties with which the problem is fraught. An expository model of this kind is constructed and its solution discussed. [ABSTRACT FROM AUTHOR]

22. Biological Indices of Stream Pollution

Author

Russell, James C.

Abstract

A thorough biological survey and evaluation is a lengthy and expensive project. The number of technically trained persons required prevent its use by most public agencies. Since public health departments are the groups most frequently concerned with measuring the effects of pollution in streams, a need exists for a simplified method of sanitary survey. Recognizing this need, the Texas Health Department assigned the writer the problem of devising a method of survey which would require a field party of two and could be conducted entirely from a mobile field laboratory.
