"Safety of Houston Drinking Water Causing Growing Concern"

"HOUSTON - The safety of drinking water is causing growing concern in Houston's neighborhoods after a series of Channel 2 investigations.

In November, we exposed high levels of a cancer-causing chemical -- chromium 6 -- in the city's drinking water.

"The city of Houston's water ranks third in the country in terms of high levels of chromium 6," said Bill Walker, managing editor at the Environmental Working Group.

Chromium 6 is the chemical made infamous by the movie Erin Brockovich."
