Some water utility representatives have protested Environmental Working Group’s report of laboratory tests that found worrisome levels of chromium-6, a suspected carcinogen, in the drinking water of 31 cities across the country. Yet the tap water industry was worried enough about the contaminant to conduct its own extensive survey in 2004 that found clear evidence of widespread chromium-6 pollution in untreated source water.
