The USAFOEHL conducted an on site wastewater characterization survey at Dover AFB DE from 25 Feb to 7 Mar 86. The survey was designed to establish pretreatment requirements by determining quantities and concentrations of pollutants expected from the industrial operations or develope and evaluate alternate solutions to decrease the discharge of wastewater contaminants. Effluents from industrial and domestic wastewater were analyzed. Kent County DE has imposed stringent pretreatment standards by changing the sampling location from a point where industrial wastewater is combined with considerably more domestic wastewater to a point where only industrial wastewater combines. Effluent limitations of cadmium were exceeded during each of the seven days sampling. Sources of cadmium were found to be metal fabrication, corrosion control and vehicle maintenance operations. Recommendations 1 Clean lift station sumps. 2 Change method of stripping. 3 Install pretreatment operation to remove chromium and Cadium from the wastewater prior to discharge into the sanitary sewer. 4 Perform periodic EP Toxicity testing on neutralized battery acid. 5 Repipe vats in building 719 to provide piping dedicated to each vat. 6 Negotiate with a solvent recovery representative to provide a system for a trial period.
