The federal government released new advisories Wednesday detailing how harmful certain chemicals in Long Island's drinking water can be.

The issue affects everyone on Long Island, but it's in the forefront for many residents in Manorville because of the hamlet's proximity to a former Navy facility, which they say polluted groundwater.

Some of the chemicals that have been found in the neighborhood's water are the ones that the Environmental Protection Agency talk about in their reports.

Ronald Martz spent his whole life in Manorville, but does not trust the water. He says he only uses bottled water to drink or cook.

"If I could figure out a way to take a shower with a gallon jug of Poland Spring I would do it," Martz says.

They are known as forever chemicals because they don't break down easily, and come from firefighter foam, Teflon cookware, stain-resistant sprays and other protects.

The chemicals have been linked to certain types of cancer and auto-immune diseases.

The EPA says concentrations as low as .004 parts per trillion can be harmful when people are exposed over a lifetime. The current standard used by New York is 10 parts per trillion.

Adrienne Esposito, of Citizens Campaign for the Environment, says this is the most significant drinking water announcement by the EPA in over a decade.

"We've never seen a drinking water advisory be this low," Esposito says. "With the current science they looked at, it's really a call to action for states and for the federal government now to act."

Esposito says systems that could help the water cost between $750,000 and $1 million.

Long Island has hundreds of public water supply wells, and tens of thousands of private wells, which would make purifying the water on Long Island very expensive.
