This is a great addition to the neighborhood and I congratulate the partners who conceived of this and made it happen.”

The Gowanus Canal was built in the mid-1800s and was used as a major industrial transportation route. Manufactured gas plants (MGP), paper mills, tanneries and chemical plants operated along the Canal and discharged wastes into it.

In addition, contamination flows into the Canal from overflows from sewer systems that carry sanitary waste from homes and rainwater from storm drains and industrial pollutants.

As a result, the Gowanus Canal has become one of the United State’s most seriously contaminated water bodies. More than a dozen contaminants, including polycyclic aromatic hydrocarbons, polychlorinated biphenyls and heavy metals, including mercury, lead and copper, are found at high levels in the sediment in the Canal.
