Improved Analysis of Highly Toxic Cr(VI) in Drinking Water

摘要

Dionex (USA) announces planned improvements to EPA 21 8.6: Determination of Dissolved Hexavalent Chromium in Drinking Water, Groundwater and Industrial Wastewater Effluents By Ion Chromatography. Increased sensitivity will result in detection levels to 0.02 ig/l. In December 201 1, Lisa Jackson Administrator for the US EPA spoke before the US senate to discuss the EPA response to public concerns about possible chromium-6 (Cr[VI]| contamination in US drinking water. The press release, titled Statement from EPA Administrator Jackson Regarding Her Meeting with 10 U.S. Senators on Chromium-6, describes new goals set forth by the EPA. In January 201 1, the EPA issued a second press release: EPA Issues Guidance for Enhanced Monitoring of Hexavalent Chromium in Drinking Water. The enhanced monitoring guidance provides recommendations on where systems should collect samples and how often they should be collected, along with analytical methods for laboratory testing.
