Abstract : Contaminated groundwater, which contained multiple heavy metals and chlorinated aliphatic hydrocarbons, from the surficial aquifer (well CC-33B) at Beach Point located in the Canal Creek Area of the U.S. Army Aberdeen Proving Ground-Edgewood Area, Aberdeen, Maryland, was evaluated for toxicity and environmental hazard. Toxicity was detected at various groundwater concentrations by 7 of 9 biomonitoring systems. when estimated maximum acceptable toxicant concentrations (MATC) were established, the data for algae, invertebrates and fish suggested that the groundwater would not be harmful at a concentration of 10% groundwater by volume. Likewise, no genotoxicity (Ames and SEC assays), develop- mental toxicity (FETAX), or chronic histopathology (9-month fish test) occurred at 10% groundwater by volume. The groundwater was considered to be a potentially excessive hazardous material to the benthic biota of the Bush River when a number of conservative assumptions (contaminant distribution and discharge rate of the aquifer) were used in the hazard assessment. However, the potential water quality impacts were judged to be minimal if a mixing zone were to be granted by the State of Maryland which allows for local exceedences of water quality standards.
