Activities sponsored by the New Jersey Chapter and associated sections

Saturday, April 25 at 7:00 PM: Screening of the documentary "Rescuing the River, the Raritan" at The Unitarian Society (East Brunswick, NJ).  Please join us! Jeff Tittel, Executive Director of the Sierra Club, will be a part of our discussion/question and answer session. Refreshments and meet & greet.

This documentary tells the story of New Jersey's Raritan River, a water source profoundly contaminated for over 200 years, and the extraordinary efforts to clean it up. The film reveals how government agencies, corporations, environmentalists, developers, scientists, and lawyers have clashed for years in their attempts to deal with the aftermath of extensive pollution and environmental neglect.

The Raritan is still the 14th most polluted waterway in the nation, with 20 federal Superfund sites and 200 state-registered toxic sites along its banks and the banks of its tributaries. See calendar posting for additional information.
