A plan to move tons of contaminated fill from a vacant Central Islip lot to a sand pit in Melville is not sitting well with residents.

The plan devised by vacant lot owner L-C Real Estate was the result of an agreement with the state Department on Environmental Conservation requiring the company to remove the fill or face a $500,000 fine.

According to an article in Newsday, the DEC calls the plan unacceptable and insists the 35,000 cubic yards of contaminated debris be moved off Long Island. It says the debris threatens Long Island's ground water.

Maureen Dolan Murphy, of the Citizens Campaign for the Environment, says the debris contains heavy metals, hydrocarbons and pesticides.

"We don't want this getting into our drinking water. The best, safest solution is to dispose of this material off the Island at a regulated facility," Murphy told News 12.

The Central Islip site is one of four in the Town Of Islip under investigation by the Suffolk County district attorney. The probe includes Roberto Clemente Park in Brentwood where 50,000 tons of contaminated debris had been dumped, a housing development for veterans in Islandia and state protected wetlands site in Deer Park.
