Arsenic Removal Technology Already Available, Says San Diego Firm

The US EPA and the Bush administration have adopted a provision requiring the allowable amount of arsenic in drinking water to be lowered to 10 parts per billion, from the previous 50 ppb. EPA administrator Christie Whitman standard by 2006 and the agency will spend $20 million on research and development of technologies.

Peter Jensen of Basin Water, however, says his firm already has perfected arsenic-removal technology. A company installation in Elk Grove, 10 miles south of Sacramento, has reduced arsenic levels from 24 ppb to non-detect levels (less than .5 ppb) while producing a waste product of only .007 percent. The self-contained system also precipitates arsenic from the waste stream, which greatly simplifies disposal.

The entire system has a small footprint designed for wellhead treatment and requires a minimal amount of electricity to operate. Basin Water has a 550 gpm arsenic removal system in operation at Semitropic Water Storage District at Wasco. “Everyone faced with implementing the new low arsenic standard will closely watch this demonstration project,” Jensen said. “Based on the outstanding results to date, this will likely be the arsenic treatment of choice throughout California and across the country.”
