| Abstract | Long Description |
A Class II Inspection was conducted at the city of Mount Vernon Wastewater Treatment Plant (WTP) from December 9-11, 1991. The WTP was performing well during the inspection for the conventional parameters of BOD5, TSS, fecal coliform, and pH. Several organic priority pollutants were detected in the samples collected; of these chloroform and lindane were detected in the plant effluent. Of the metals detected in the effluent, only copper and silver were found in concentrations above chronic or acute EPA water quality criteria. Bioassay organisms showed no acute toxicity in the plant effluent. While Daphnia magna tests showed no chronic effects, fathead minnow tests indicated a LOEC of 12.5% effluent. A dye study found the effluent discharge was into a well-mixed area in the river. |
