| Abstract | Long Description |
A Class II Inspection was conducted at the Wenatchee Wastewater Treatment Plant on December 11-13, 1989. Weekly average NPDES permit limits for total suspended solids (TSS) and biochemical oxygen demand (BOD5) were being met at the time of the inspection. Effluent concentrations of copper, lead, mercury, silver, zinc, cyanide, and 4,4'-DDT exceeded the Environmental Protection Agency (EPA) acute and/or chronic criteria for freshwater. Bioassays showed no effluent toxicity to Microtox, some acute toxicity to rainbow trout, and moderate acute and chronic toxicity to Ceriodaphnia dubia. Preliminary results of the ongoing centrifuge study of effluent particulates are presented and discussed. |
