The cleanup of an age-old industrial site in Tarrytown, Westchester County, is finally taking shape.

The cleanup site is prime waterfront property on the Hudson River.Last week, the New York State Department of Environmental Conservation formally selected a cleanup plan to remove pollution at the former General Motors North Tarrytown Assembly Plant site.

The $10 million cleanup, which will take about two years to complete, is extensive, will cleanup lead, chromium, copper, zinc, mercury, trichloroethene, petroleum products, methane and mercury that has contaminated the soil and groundwater on the property.

The plan also calls for dredging a small portion of the Hudson River to remove contaminants. 

The industrial use of the site began in the 1830s, when a brickyard was built. It later became the home of a drill manufacturer, and then later an auto plant. General Motors used the site until 1996.
