Implementation of a multiple biomonitoring approach to evaluate the potential for impact from an industrial discharge
Tóm tắt
Over a 2-year period, an industrial discharger implemented a program to determine if there was a potential for in-stream impact from its discharge, and, if necessary, to eliminate that potential. Six basic study designs were used. These included: (1) ambient toxicity tests using indicator organisms; (2) in-stream waste concentration (IWC) chronic testing using indicator organisms; (3) on-site flow-through toxicity testing using indicator and resident species with receiving stream water as the diluent; (4) in situ acute toxicity studies using indicator and resident species; (5) biological surveys of the receiving stream; and (6) artificial stream studies. The outcome of the studies resulted in conclusive data on which to base the design of a diffuser to dilute the effluent 1:20. This concentration was well below the lowest acute no-observed-effect concentration (10% effluent) determined using sensitive resident test species. In this manner, impact from the effluent on the James River had been reduced so that even the most sensitive resident species were protected. As a result of the study, the facility's permit was modified so that toxicity tests were made only on effluent diluted with receiving stream water to represent dilution at 1Q10 rather than 100 percent effluent. Follow-up studies have concentrated on a series of toxicity tests which were designed to identify the toxicants in the final effluent.
