Evaluation of several biological monitoring techniques for hazard assessment of potentially contaminated wastewater and groundwater. Volume 2. Aberdeen Proving Ground Wastewater Treatment Plant. Final report, November 1988-December 1991
An evaluation of several biological monitoring techniques for hazard assessment of potentially contaminated effluent was conducted at the Aberdeen Proving Ground Wastewater Treatment Plant (APG-WWTP), Aberdeen Proving Ground, MD, from early May 1990 to February 13, 1991. An array of biomonitoring tests structured in a tiered hazard assessment framework was used in the evaluation of the effluent. Several levels of biological organization were included in the array of tests. Acute toxicity was evaluated on daily 24-h composite samples using a 5- and 15-min Microtox assay which employs microbial (Photobacterium phosphoreum) bioluminescent activity. Three 24-h LC50 rotifer (Brachionus rubens) toxicity tests were conducted using 24-h composite samples. The following chronic tests were all performed three times using 24-h composite samples: 96-h EC50 algal (Selenastrum capricornutum) growth test, 7-d daphnid (Ceriodaphnia dubia) survival and reproduction test, and 7-d fathead minnow (Pimephales promelas) survival and growth test. The acute rotifer tests and all chronic tests were conducted during the same periods in order to compare toxicological responses between biomonitoring systems....
