| Abstract |
Comparative laboratory toxicity tests using Ceriodaphnia reticulata and the fathead minnow Pimephales promelas were conducted to establish relationships between the toxicity of a sewage treatment plant effluent containing high concentrations of zinc, toxicity of the effluent in the receiving water, toxicity of zinc added to the receiving water and a reference water, and receiving water biota survey data. Water and biota were sampled under summer (3 times), fall (once) and winter (once) conditions over a one year period. The relationships were used in evaluating the protectiveness of a site-specific water quality criterion derived for zinc. A strong correlation between the effluents toxicity to daphnids was established, however, toxicity correlation with adverse impact on river biota could not be established. |

Comparative laboratory toxicity tests using Cariodaphnia reticulata and the fathead minnow Pimephales promelas were conducted to establish relationships between the toxicity of a sweage treatment plant effluent containing high concentrations of zinc, toxicity of the effluent in the receiving water, toxicity of zinc added to the receiving water and a reference water, and receiving water biota survey data. Water and biota were sampled under summer (3 times), fall (once), and winter (once) conditions over a one year period. The relationships were used in evaluating the protectiveness of a site-specific water quality criterion derived for zinc. A strong correlation between the effluents toxicity to daphnids was established, however, toxicity correlation with adverse impact on river biota could not be established. It was concluded that the effluent did not adversely affect taxa composition and abundance at 2 miles (3.2 km) below the discharge to the river. At 2 miles the zinc concentrations ranged from 100 to 154 g/l and averaged 144 g/l on 3 of 4 sampling dates indicating that a site-specific criterion average concentration of 145 g/l, approximately 3 times greater than the national average concentration, would be protective of river biota. |
