Abstract:

The toxicity of contaminated Old O-Field Edgewood Area of Aberdeen Proving Ground groundwater and the reduction andor 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 adsorptionbiological 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.
