NEW YORK (CBSNewYork/AP) — New York conservation officials have selected cleanup plans for an industrial site on Long Island to remove longstanding groundwater contamination.

The Department of Environmental Conservation says it will target groundwater hot spots at Operable Unit 3 of Northrop Grumman’s Bethpage Facility to diminish the threat to wells that provide public drinking water.

The plan, which follows public comments, calls for installing groundwater extraction wells, excavating fill contaminated with polychlorinated biphenyls and chromium and covering part of the site with buildings, pavement and sidewalks or soil.

“DEC listened to and carefully considered the concerns of the public before selecting a remedy to address the long-standing contamination at Northrop Grumman site,” Commissioner Joseph Martens said in a statement. “These actions help protect public health and the environment of Nassau County.”

The Bethpage contamination is on the state registry of inactive hazardous waste sites.

It was used historically for disposal of various wastes generated by industrial operations in the Grumman industrial complex.
