The U.S. Army Alternative Technology Program, Aberdeen Proving Ground, MD, has investigated an alternative method for disposing of sulfur mustard 2,2DICHLOROPHENYL SULFIDE HD, a chemical warfare agent under the chemical stockpile disposal program. The mineralization of HD, through hot water hydrolysis followed by biodegradation in sequencing batch bioreactors, has been demonstrated to be an effective technology. In this report, the feasibility of discharging effluents, produced from the bioreactors, to a Federally Owned Treatment Works FOTW has been investigated. The chronic toxicity of bioreactor effluent and effluents produced from an FOTW model were evaluated using the fathead minnow Pimephales promelas and daphnid Ceriodaphnia dubia. The results from this research indicate that the discharge of bioeffluent to a wastewater treatment plant will not be toxic to ceriodaphnia and fathead minnows.
