"The operation and performance of the Cache Creek Sewage Treatment Plant was evaluated over a 4 day period. Plant influent and effluent was sampled daily and analyzed for numerous parameters including BOD₅ and non-filterable residue, as well as metals. Several locations in the plant and in the receiving waters were sampled daily and analyzed for indicator bacteria. A continuous fish bioassay was run on the final effluent but was not entirely successful due to equipment malfunctions. Other parameters measured included total residual chlorine, aeration tank dissolved oxygen, and mixed liquor stability. The chlorine contact chamber was evaluated using dye tracer techniques. Recommendations are made to improve plant performance and reliability"--Abstract, page i. Issued also in print format.
