Data Analysis <br />Data from the tests were analyzed on a Computer Source 386 personal computer. Where <br />applicable, LC50's were calculated using EPA's TOXDAT Multi-Method Program according to the <br />binomial, probit, or moving average methods. Statistically significant differences between control <br />and exposed organisms were determined using the TOXSTAT software developed at the <br />University of Wyoming. <br />RESULTS <br />The results of the tests are summarized in Appendix 2. There was no mortality seen in <br />the Daphnia magna test where survival was 100% in every effluent concentration. Survival was <br />also 100% in the control. <br />DISCUSSION <br />The first accelerated test sample passed the whole effluent toxicity test guidelines for the <br />Daphnia magna. One more accelerated test must pass in a row for accelerated testing to be <br />discontinued and normal testing to resume. <br />REFERENCES <br />APHA/AWWANVPCF. 1985.
