Comparative toxicity of SRC-I wastewater to aquatic organisms. Final technical report
SRI International performed a series of acute and chronic toxicity studies on SRC-I wastewaters using fish, zooplankton, and algae as test organisms. The tests were designed to determine the toxicity of SRC-I wastewaters to quatic organisms and based on differences in toxicity of the various water samples, to evaluate the efficacy of various wastewater treatment methods. Survival data from acute and chronic daphnid studies indicate that phenol recovery markedly reduced wastewater toxicity. In treatment processes that did not include phenol recovery, powdered activated carbon reduced toxicity more effectively than granulated activated carbon. All treated water supported algal growth in excess of that in controls, particularly those waters subjected to phenol recovery. The toxicity of each SRC-I wastewater sample was compared with that of a corresponding synthetic salt solution to determine whether the salt load was the toxic element. The wastewaters typically exhibited higher toxicity than their associated salt solutions. The effect was greatest in the daphnid chronic studies. The aquatic ecotoxicity tests were performed as part of ICRC's post-Base-line environmental R and D program. One objective of the program was to evaluate the impact of phenol recovery on effluent quality. Another objective was to assess the potential impact of wastewater discharge on aquatic organisms. The results of this study have been integrated with results from the rest of the R and D program, and are documented in ICRC's Integration Report for SRC-I Post-Baseline Environmental R and D. 7 references, 10 figures and 22 tables.
