The EPA head says tighter drinking water standards are probably coming after a carcinogen was found in many cities' water.Environmental Protection Agency Administrator Lisa Jackson said she was troubled that chromium 6 was detected in the tap water of 31 cities, including Chicago.

Jackson said the agency will work with local officials to determine how widespread the problem is and that they will adjust standards that were set two decades ago.
