Arsenic Pilot Plant Operation and Results- Socorro Springs, New Mexico- Phase 1

Abstract

Sandia National Laboratories (SNL) is conducting pilot scale evaluations of the performance and cost of innovative water treatment technologies aimed at meeting the recently revised arsenic maximum contaminant level (MCL) for drinking water. The standard of 10 µg/L (10 ppb) is effective as of January 2006. The first pilot tests have been conducted in New Mexico where over 90 sites that exceed the new MCL have been identified by the New Mexico Environment Department. The pilot test described in this report was conducted in Socorro New Mexico between January 2005 and July 2005. The pilot demonstration is a project of the Arsenic Water Technology Partnership program, a partnership between the American Water Works Association Research Foundation (AwwaRF), SNL and WERC (A Consortium for Environmental Education and Technology Development).

“…Testing the collected treatment media for arsenic was beyond the scope of this study. However, there are reports of arsenic treatment media capacity that go up to and beyond 5 mg of arsenic per gram of media (Aragon et al, 2007;Westerhoff et al, 2006Westerhoff et al, , 2008.…”
