City officials announced yesterday that they'll start testing the city's water supply for hexavalent chromium. A study released late last month showed that Chicago's water supply contained higher levels of the metal than what was the standard allowable level in California. The announcement closely followed a memo released by the EPA to more closely monitor levels of the metal made infamous in the movie Erin Brokovich.
