L .- <br />RESULTS <br />Water Chemistry <br />The waters' initial chemical characteristics appear in Table 2. <br />Final chemical characteristics can be found in Appendix A-Final <br />Chemistries. <br />Toxicity Tests and Survival data <br />Acute Toxicity Tests - <br />Mock effluent and spring water prepared with NaHCO3 caused the <br />highest mortalities followed by the unmanipulated effluent and <br />spring water. - See Table 3 for mortality results. <br />Statistical Analysis <br />Appendix C - Results of Spearman-Karber <br />The following LCSO's were calculated: <br />Effluent Toxicity Test <br />B-seam Spring Water Toxicity Test <br />Mock Effluent NaCl <br />Mock Effluent NaHC03 <br />Mock Spring Water NaCl <br />Mock Spring Water NaHC03 <br />LC50 = 59 o Effluent <br />LCSO = 61 % Spring Water <br />LCso = 87 % Stock <br />LCso = 29 % Stock <br />LCso = 89% Stock <br />LCso = 27% Stock <br />EDTA Chelations Tests: <br />Effluent EDTA - 1000 Mortality <br />Spring Water EDTA - 100% Mortality <br />NaHC03 Mock Effluent EDTA - 100% Mortality <br />Metals Analysis <br />The Metals Scans on the Effluent and the B-seam Spring Water Found <br />Significant Sodium Concentrations of 1160 mg/L and 1115 mg/L <br />respectively. <br />See Appendix B - Metals Analysis Results. <br />-4- <br />COMMER CIALTESTING 8r ENGINEE RING CO. <br />;6o Lf~ <br />~ainal Wa~ermarhetl For vow Protenw~ <br />
