Description:
Arsenic in drinking water is a known carcinogen with additional adverse human health impacts. For the 4,100 affected systems, 37 to 55 cancer cases per year are estimated, with about half projected to result in deaths if treatment solutions are not implemented. The Environmental Technology Verification (ETV) Drinking Water Center is a partnership between the USEPA-ORD, and NSF International to provide independent evaluations of water treatment technologies. ETV is conducting evaluations of technologies for the removal of arsenic in drinking water at several field sites across the United States. ETV provides information to help states, utilities, and other organizations select appropriate technologies to meet the 10 ppb arsenic regulatory standard. Many of the ETV verified technologies demonstrated the capability to reduce arsenic levels in drinking water to 5 ppb or less. This provides several viable off-the-shelf products for water systems required to install treatment to meet the new standard. State agencies have indicated ETV studies may also help to minimize pilot testing requirements and help expedite the approval and installation of technologies. Also, ETV results help provide technology vendors with valuable data on technology weaknesses that may be corrected in subsequent upgrade.
