This powerpoint presentation begins by providing a brief overview of the Baldwin Park Operable Unit (BPOU) located in Southern California's San Gabriel Valley. It was declared a Superfund Site in 1984
due to volatile organic chemical (VOC) contamination. The BPOU Committee is profiled, along with its work to meet U.S. Environmental Protection Agency (USEPA) cleanup requirements and
achieve standards for potable use of the treated water. Perchlorate is highlighted as the contaminant of concern, along with perchlorate treatment technologies. The presentation focuses on perchlorate removal by ion exchange (ISEP™), along with efforts at brine management. Presentation conclusions indicate that:
the BPOU has led the nation in approaches to
perchlorate removal, i.e. in
2001 the first regenerable IX process installed at La Puente, and in
2002 the first single pass IX process installed at Cal Domestic;
both regenerable and single pass ion exchange
systems are capable of removing perchlorate;
advent of perchlorate-selective resins has made
single pass IX cost-effective; resin costs less than
salt costs;
however, for groundwater contaminated with both
perchlorate and nitrate, other options will need to be
considered. Includes tables, figures.
