Hexavalent Chromium Found in Tap Water: Is Your City on This List?

drinking waterWhat do Americans in 31 of the country's cities now having in common with Julia Roberts? They've both got a connection to hexavalent chromium, a chemical the Environmental Working Group (EWG) says has shown up in the drinking water of 31 of 35 American cities. It's the chemical made famous by the movie Erin Brockovich, which won Roberts an Academy Award for her portrayal of the real-life legal assistant who gave the film its name.

The real Brockovich took down Pacific Gas & Electric, the company responsible for polluting a town's water supply with none other than hexavalent chromium. And now the EWG says the chemical is floating around in the water in places from Norman, Oklahoma to Bethesda, Maryland.


If you saw the film, you may remember the chemical poisoned people in the town, and it's classified as a "human carcinogen" by the Environmental Protection Agency. So should we be worried?

According to scientists, yes. Previously thought of as a risk if you're inhaling it, scientists have recently discovered tumors in animals who have ingested the chemical, leading to liver and kidney damage, leukemia, and stomach cancer. The following cities made the EWG list (in descending order of amount of hexavalent chromium found):

1. Norman, Oklahoma

2. Honolulu, Hawaii

3. Riverside, California

4. Madison, Wisconsin

5. San Jose, California

6. Tallahassee, Florida

7. Omaha, Nebraska
