Too many California towns have arsenic in tap water, group says

An environmental group said Monday that 55,000 people statewide are at risk of drinking tap water contaminated with arsenic, and many of the communities are poor, mostly Latino towns in the San Joaquin Valley.

The Environmental Integrity Project based in Washington, D.C., said required warnings to water customers fail to explain the dangers from arsenic exposure and need to be strengthened.

A total of 95 water systems have average arsenic levels of more than 10 parts per billion, which is above the federal maximum contaminant level, the group said in its report. Arsenic is a cancer-causing chemical linked to other health problems
