Abstract
The U.S. Environmental Protection Agency issued a water-quality based policy in March, 1984 which includes control of toxicity in effluents if receiving water impact occurs. Toxicity tests can be used to measure toxicity, estimate additional removal necessary to avoid impact, establish permit limits and for compliance monitoring. Toxicity tests are a direct measure of the effect for which control is sought and often are cheaper than chemical analyses.
