Evaluation of Several Biological Monitoring Techniques for Hazard Assessment of Potentially Contaminated Groundwater at the Old O-Field Site at the Edgewood Area of Aberdeen Proving Ground
Abstract
The toxicity of contaminated Old O-Field (Edgewood Area of Aberdeen Proving Ground) groundwater and the reduction and/or elimination of toxicity by various treatment processes were evaluated. The study was divided into a bench scale and pilot scale study. The bench scale studies consisted of 48-h definitive acute toxicity tests run with daphnid neonates (Daphnia magna) and juvenile fathead minnows (Pimephales promelas) exposed to untreated Old O-Field groundwater and groundwater treated by (1) metals precipitation, (2) UV oxidation (H2O ), (3) carbon adsorption, and (4) carbon adsorption/biological sludge. The pilot scale studies consisted of (1) several 96-h definitive acute toxicity tests run with two freshwater and two saltwater invertebrates and fish and (2) Ames mutagenicity assays. Acute toxicity tests were run on untreated Old 0-Field groundwater and groundwater treated by (1) metals precipitation, (2) UV oxidation (H2O2), (3) air stripping, and (4) carbon adsorption during the pilot scale study. The freshwater invertebrate and fish used in the study were daphnid neonates and juvenile fathead minnows, respectively.
