Raritan Valley Group of the Sierra Club Joins AmeriCorps NJ Watershed Ambassadors’ Volunteer Stream Monitoring Training

Saturday, May 30 at 9:00 AM:  Biological stream monitoring training at Duke Farms (Hillsborough, NJ).  Water quality is a top priority of our Sierra Club Group and something we can all get more involved in as citizen scientists! The AmeriCorps New Jersey Watershed Ambassadors for the Raritan region will inform us how water quality is monitored by collecting benthic macroinvertebrates. A hands on overview for monitoring stream pollution will be led by the four Raritan region ambassadors, Brittany Musolino (Union County Dept. of Parks and Recreation), Alexandra Walczak (Raritan Headwaters Association), Jon Dugan (New Jersey Water Supply Authority), and Rachel McGovern (Stony Brook Millstone Watershed Association).  Training will include a 1.5 hour classroom component, and 1.5 hours in a nearby stream, so please dress ready to go outside and enter a stream. Waders or rain boots are strongly recommended. The event is free and open to the public, however registration is needed in advance to insure enough testing materials for everyone to learn and enjoy!  Please reserve your spot today by using the online form at Stream Monitoring Training. Any questions about the workshop please contact Alexandra Walczak at No background is necessary. Must be 15 years or older. (12+ if accompanied by an adult.)

A potluck lunch will take place after the hands-on sessions to meet current local Sierra Club members and all interested other participants!  This informal lunch picnic will be held at Duke Farms visitors barn building on the patio next to the cafe. (It is optional to bring a potluck dish, and the cafe has excellent offerings for lunch options too.)  Our May 30 event will take place at Duke Farms (phone: 908-722-3700), 1112 Dukes Parkway West, Hillsborough, NJ, just off Route 206.

Rescuing the River, the Raritan: A powerful documentary

Please join us for a free screening of the documentary, "Rescuing the River, the Raritan", on Saturday, April 25, 2015 for Earth Day at 7:00 pm at the Unitarian Society, 176 Tices Lane, East Brunswick, NJ  08816.  Jeff Tittel, Executive Director of the Sierra Club, will help lead a discussion/question and answer session.  Refreshments will be served.  Meet and 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.
