Hopi Cultural Center

The U.S. Environmental Protection Agency has ordered the Hopi Cultural Center to reduce the arsenic in its drinking water.

A leech occupies the top spot in the food chain at Montezuma Well near Camp Verde. Surprisingly, its body contains the highest level of arsenic ever recorded in a living organism.

The Hopi Tribe is seeking $20 million from the federal government to clean up arsenic in drinking water.

In the Hopi communities of First and Second Mesa, naturally occurring arsenic levels in drinking water exceed federal limits by as much as  four times.

Arsenic has been linked to cancers and circulatory problems.

Hopi water director Lionel Puhuyesva says  the tribe decided to sue the government, rather than ask Congress for money.
