Cities not testing water for widely-found carcinogen

[patric]

The tap water of most U.S. cities tested contains hexavalent chromium, a probable carcinogen made famous by the film "Erin Brockovich," an environmental group reports Monday.
The study by the Environmental Working Group, the first nationwide analysis of the chemical in U.S. water to be made public, detected its presence in 31 of 35 cities tested. It found the highest levels in Norman, Okla....

And why would we want to do that?

Wouldn't that constitute an unwarranted government intrusion into people's lives??

Can anyone conveniently convert the mg/m³ (etc) in the OSHA info to the PPM in water referred to in the article?

It's incredibly small amounts, not enough to get one's panties in a wad.

12.90 part per billion is what they found in Norman

12.90 part per billion is what they found in Norman

How does that compare to the OSHA safe levels which are not in parts per million or parts per billion.  Conversion from one system of measurement to the other is what is missing so far.

I believe that will get us from ppm in air to mg/m³ in air and vs. but not to either in drinking water.  TLVs for ingestion are sometimes different than for inhalation too.

I understand they have also found dihydrogen monoxide as well.

Dangerous stuff.  Kills a lot of people each year.

I've had a problem with that in my washing machine lately.

My dishwasher had been leaking it, had to replace it.
