The Village of Palm Springs was investigating technologies to remove total organic carbon from its groundwater source prior to disinfection in order to meet the U.S. Environmental Protection Agency (USEPA) Stage 1 D/DBP Rule for trihalomethanes (THMs) and haloactetic acids (HAAs). The treatment options investigated were ozonation of the raw water prior to the existing lime softening process and MIEX® resin pretreatment of the raw water followed by the existing lime treatment plant. MIEX® resin pretreatment was found to be very effective at reducing the raw water total organic carbon (TOC) level by an average of 71% which allowed compliance with the disinfection byproduct (DBP) standards after downstream disinfection. Ozonation was very effective at reducing the raw water color but removed very little TOC and therefore did not allow compliance with the DBP standards after disinfection. A MIEX® resin pretreatment system was therefore selected by the Village of Palm Springs for installation at its 4 and 6 MGD groundwater treatment plants and these plants are scheduled to start up around October 2004. Includes 4 references, tables, figures.
