The San Gabriel Valley groundwater basin is located in an area east of Los Angeles covering more than 160 square miles. The Baldwin Park Operable Unit (BPOU) is the largest area of groundwater contamination within the San Gabriel Valley groundwater basin. Although chlorinated hydrocarbons were initially the driving force for remediation, a change in perchlorate detection technology and the anticipated drinking water Maximum Contaminant Level's (MCL's) have caused perchlorate to emerge as a new pollutant of concern. Currently, three groundwater treatment plants located within BPOU are utilizing ion exchange resin technology to remove the perchlorate from the groundwater. This technology generates a concentrated brine waste stream that requires disposal. For the last three years this brine has been discharged into the County Sanitation Districts of Los Angeles County's (Districts') sanitary sewer system. As MCL's for perchlorate continue to be lowered and more water companies are forced into some form of treatment, the Districts anticipate increased pressure for brine discharges to the sewer. A review of the current perchlorate removal installations in the BPOU will be presented along with issues surrounding brine discharges to the sewer and sewerage system impacts the Districts have experienced.
