TOO MUCH CHROMIUM=BAD

The types of chromium discussed in the movie Erin Brockovich was chromium three and chromium six (hexavalent chromium).  Chromium three was okay to have in the water, but the water in Hinkley was contaminated by chromium six.  It got into all of the water going through the city.  Chromium six leads to a large amount of serious health problems.  These health risks include:   skin rashes, upset stomachs, ulcers, respiratory problems, weakened immune systems, kidney and liver damage, alteration of genetic material, lung cancer, and DEATH.  As you can see chromium six is not good, but on the other hand too much of chromium three is not that big of a threat to your health.  It only causes mild skin rashes.  It's probably not a good idea to go around drinking chromium six, just saying.
