Baldy Mesa Water District is an independent Special District, encompassing twenty-four square miles within Victor Valley, serving residents of the City of Victorville. Baldy Mesa is faced with finding a viable treatment process for arsenic removal that can be approved and implemented by January 2006. Unlike other purveyors who may have access to blending sources or imported water, Baldy Mesa has no choice but to treat all of their affected well sites. The primary objective of this paper is to compare various arsenic treatment technologies for use in municipal drinking water systems. This study focuses on the use of high efficiency ion exchange system to treat arsenic levels above the new Federal standard of 10ppb in Baldy Mesa. The District and its neighbor, Victor Valley Water District, engaged an independent engineering firm to perform a small-scale pilot project that tested iron medias to determine their expected performance and economics. An additional demonstration took place at the same location using a 100gpm packaged ion exchange system for arsenic removal. Performance indicators showed that ion exchange will always reduce arsenic to non-detect levels regardless of varying water quality. For other technologies tested, however, the results appeared to be very inconsistent. During the pilot testing, the high efficiency ion-exchange system used processed 2.2 million gallons, resulting in a waste product of 0.05% (1,100) gallons of waste brine. No pH adjustment was required for the removal of arsenic although the pH often exceeded 9.0.
