| Short Description |
A Class II Inspection was conducted in October 1991 at the city of Prosser Industrial/Domestic Wastewater Treatment Plant in Benton County, Washington. The Prosser facility is a single stage recirculating trickling filter plant followed by a sequential batch reactor (SBR). Inspection data found the Prosser STP was producing a fairly good effluent quality. Effluent concentrations were within NPDES permit limits with the exception of one fecal coliform sample.

| Abstract | Long Description |
A Class II Inspection was conducted in October 1991 at the city of Prosser Industrial/Domestic Wastewater Treatment Plant in Benton County. The Prosser facility is a single stage recirculating trickling filter plant followed by a sequential batch reactor (SBR). Inspection data found the Prosser STP was producing a fairly good effluent quality. Effluent concentrations were within NPDES permit limits with the exception of one fecal coliform sample. Inspection BOD5 and TSS loadings approached or exceeded design capacities included in the NPDES permit. Approximately 10% of the BOD5 and TSS loadings were from domestic sewage, with the balance from three principal industries. Effluent priority pollutant organics and metals concentrations were less than EPA acute and chronic water quality toxicity criteria for freshwater. Bioassays found no toxic effects due to the effluent. |
