The survival IC was determined by inspection since survival was not <br />reduced by z 25 percent in any of the effluent treatments, relative to the dilution water <br />control. The chronic IC was calculated using USEPA approved software (Norberg-King <br />1993). Statistical methods were as follows: <br />
