F/H Area ETF effluent (H-016 outfall) ceriodaphnia survival/reproduction test, test date: September 21, 1989
This toxicity test was conducted to determine if the effluent from the F/H area of Savannah River Plant causes death (acute toxicity) or reduction in the reproduction of the test organisms (chronic toxicity) during a seven day period. A series of dilutions of the effluent are set to determine how much the effluent must be diluted before toxic effects are no longer noted. Acute toxicity is checked by statistically analyzing whether significantly more organisms die in the effluent dilutions than in the control treatment, and, if significantly more die, how much the effluent must be diluted so as to kill only 50% of the test organisms (the LC50). Chronic toxicity is checked by statistically analyzing whether significantly fewer young are produced by test organisms exposed to the effluent dilutions. Results indicate the lowest effluent concentration which shows a toxic effect (the LOEC) and the highest effluent concentration which does not demonstrate an effect (NOEC). Results are discussed.
