Cancer-Causing Hexavalent Chromium In Tap Water Of 89% Of US Sampled Cities

Medical News

Carcinogenic hexavalent chromium, the "Erin Brockovich chemical" was found in the tap water of 31 cities out of a total of 35 tested by The Environmental Working Group. The scientists estimate that at least 74 million people in the USA in 42 states regularly drink chromium-tainted water, and a considerable proportion of it is in the carcinogenic hexavalent form.

Hexavalent chromium is recognized as a human carcinogen. Some workers are exposed to the chemical, and exposure is known to sometimes occur among those who handle chromate-containing products, as well as those who arc weld stainless steel. The European Union has the world's strictest laws regarding hexavalent chromium. Hexavalent chromium use in the European Union in electronic equipment, for example, is largely prohibited by the Restriction of Hazardous Substances Directive.

Highest levels of hexavalent chromium in tap water were found in Norman; Oklahoma, Riverside; California, and Honolulu; Hawaii. Safety limits proposed by California regulators were exceeded in samples from 25 US cities, the scientists revealed.[...]
