This powerpoint presentation begins by providing a brief overview of the East Valley Water District in California's San Bernardino County and historic perchlorate levels. In 2006, the district started a planning level
study to evaluate a centralized treatment
facility consisting of
four existing wells (Wells 24A, 24B, 25, and 107) that would
treat for both perchlorate and nitrate. Project objectives included the following:
develop conceptual-level design criteria for
ion exchange and biological treatment;
estimate life cycle costs; and,
recommend treatment technology. Biological treatment alternative is outlined, along with life cycle cost analysis assumptions and a product flow comparison. Presentation conclusions and recommendations include the following:
at this facility for low-level perchlorate and
nitrate treatment, ion exchange is less
expensive on a per acre-foot basis;
use non-regenerable ion exchange for
perchlorate removal; and,
use regenerable ion exchange for nitrate
removal. Includes tables, figures.
