I'll just go directly to the part you don't see too often:
While the methodology used by the environmentalists was questionable — in each of 35 cities, one member of the group turned on the kitchen tap to collect a single sample of water — it got the attention of the national media, a number of Congressmen and the Environmental Protection Agency.
"Questionable" is a very kind word for that method. "Laughable", or "Poppycock" would be more accurate. Let's put it this way: it's less reliable than a Jim Doyle promise.
And it is no surprise that EPA is interested. They're always interested in retaining their jobs.
The good news is it’s relatively easy and cheap to remove the chemical from water, said Biedrzycki. The bad news is that no one knows how much chromium-6 is dangerous.
Cantor said much more rigorous testing needs to be done before conclusions can be drawn.
“Obviously one sample in one city is not enough to base conclusions on,” Cantor said. “Also, does the chromium-6 come from the source water, interactions with the piping or the type of faucet the sampler happened to use?”
Or from a handy pack of chrome-dust that the sampler poured into the water?
Grande [Madison's water guy] said he does not believe that chromium-6 detected in Madison is the result of environmental contamination. He said he is also concerned that the unstable nature of chromium could nullify test results.“It’s unstable,” Grande said of chromium. “It can be changed by air, chlorine and other factors that may influence the results.
Chlorine, eh? Gee. Would Madison (and Milwaukee) use chlorine in their water systems? (Just asking...)
To top it off, there's this:
From 1996 to 2008, 196 cancers were identified among residents of the census tract that includes Hinkley — a slightly lower number than the 224 cancers that would have been expected given its demographic characteristics, said epidemiologist John Morgan, who conducted the California Cancer Registry survey
So maybe Chromium-6 is actually GOOD for you.
