AWWA JAW19253

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 Water and Sewer Utility in Evansville, Indiana, chose chlorine dioxide as the most feasible method for controlling THMs. The performance of a 100 gpm (6.3-L/s) pilot plant that incorporated chlorine dioxide treatment was compared with that of a full-scale plant that used chlorination. Chlorine dioxide was so effective for reducing THMs that it has been used in Evansville's full-scale plant since 1983. Includes 19 reference, tables, figures.
