Description:
Because of the November 1979 amendment to the National Interim Primary Drinking Water Regulations, many utilities were faced with changing their disinfection practices to comply with the 0.10-mg/L maximum contaminant level for trihalomethanes (THMs). After considering various options, one utility, the Evansville (Ind.) Water and Sewer Utility, chose chlorine dioxide disinfection as the most feasible method for controlling THMs. The performance of a 100-gpm (6.3-L/s) pilot plant that incorporated chlorine dioxide was so effective for reducing THMs that it has been used in Evansville's full-scale plant since 1983.
