Description:
As a result of the 1976 consent decree (Natural Resources Defense Council et al. v Train suit), EPA is obligated to identify which of the 129 priority pollutants are present in industrial wastewaters and to determine the ability of various wastewater treatment technologies to remove these pollutants. This project investigated the source of priority pollutants, assessment of the wastewater treatment plant, and priority pollutant removal efficiency for a single primary zinc manufacturing plant. Forty-eight hour composited samples were collected from the following streams: (1) plant intake water, (2) sanitary discharge, (3) gas scrubber wastewater, (4) lagoon wastewater, and (5) plant effluent. The plant treats all process, sanitary, and storm run-off wastewater in a lime precipitation/solids clarification treatment plant. Results indicate high levels of zinc, cadmium, and chrome being generated but being removed to acceptable state requirements by the treatment plant. Low levels of several priority pollutant organics were found, originating either in the city water supply or being generated chemically within the manufacturing plant.
