Back Bay Charles River - Charles River Watershed AssociationCRWA began what we call our Urban Smart Sewer project in the fall of 2013 with a three year grant from the Scherman Foundation's Rosin Fund, and support from Eaglemere Foundation. Our first orders of business were to discover whether the distributed wastewater treatment plants we had investigated with our Littleton, MA, Smart Sewer project could be sited in dense urban confines. To help us, we put together a technical advisory committee (TAC) made up of principals from federal, state, and Boston agencies.

5 Methods Used by CRWA to Monitor the Charles River

The Charles, like any natural environment, is a complex, interconnected, living, changing system. At CRWA, our work is guided by the philosophy that we cannot address and manage problems in the Charles without understanding them. Collecting and analyzing our own data is a critical piece of this process and the backbone of CRWA’s advocacy and design work. Whether monitoring is conducted by staff, interns or volunteers, everyone follows strict monitoring protocols to ensure we collect the most accurate data available. In celebration of World Water Monitoring Day, read on to learn more about five ways CRWA monitors the Charles every day.

Kendall Plant to Eliminate Thermal Pollution in the Charles River

Posted by Amy Rothe

Kendall_plant_300x200pxOn May 20, 2014, an important component of Charles River Watershed Association’s (CRWA) and Conservation Law Foundation’s (CLF) settlement of the GenOn Kendall Cogeneration Plant’s (now owned by Veolia North America) Clean Water Act discharge permit became a reality. In a ribbon-cutting ceremony at the Museum of Science, Veolia commemorated its “Green Steam” project, which includes the completion of a 7,000-foot steam pipeline extension from its Cambridge plant to Boston, and a planned reconfiguration of the combined heat and power plant. The pipeline connection and the planned reconfiguration will eliminate thermal discharge of heated water from the plant into the Charles. Previously, the plant discharged approximately 70 million gallons of heated water into the Charles daily, a volume often equal to the entire flow of the river during summer months.

CRWA and CLF began negotiations with the plant about the heated discharge in 1998, when then-owner Southern Energy upgraded the Kendall Square Station. CLF and CRWA argued that the plant’s discharge of heated water into Charles not only destroyed aquatic habitat, fish and other wildlife, but was also partly responsible for toxic algal blooms in the Charles River Lower Basin. It took CRWA and CLF over a decade of negotiations with first Southern Energy, followed by successive companies Mirant and GenOn, for the plant to develop a co-generation plan that ended the heated water discharge to the river. During this time, CRWA worked closely with GenOn’s Shawn Konary, who was the plant representative responsible for the new technology.

“Veolia is to be commended for the construction of the new pipe that carries the steam into Boston,” said Bob Zimmerman, CRWA’s Executive Director. “This is an innovative, energy-generating, and river friendly solution that should serve as a model for other cities.”

In addition to minimizing environmental impacts to the Charles River, Veolia’s plan to now capture and reuse heat will reduce greenhouse gas emissions in the cities of Boston and Cambridge.

4 Ways Volunteers Will Make an Impact for the Charles River this Earth Day

On April 26, 2014, come rain or shine, over 4,000 volunteers will help beautify the Charles River in honor of Earth Day. Celebrating its 15th year, Charles River Watershed Association’s (CRWA) Earth Day Charles River Cleanup brings together volunteers from over 150 teams, who participate at multiple locations along the 80-mile Charles River.

Here are a few ways volunteers will make a huge difference at the event:Charles River Cleanup

  1. After the long winter, trash previously covered by snow and ice is now visible and free to blow into waterways. Participating volunteer teams pick up this litter and prevent it from entering the Charles. In 2012, volunteers removed a shopping cart, computer and several tires from the river!

  2. In addition to picking up litter from riverbank, volunteers will venture onto the river in canoes. This year, volunteers with Leinenkugel’s Canoes for a Cause will paddle past Brighton to reach trash that has drifted far from the shore, while volunteers from Big Heart, Little Feet will fish out litter from Populatic Pond. Volunteers in Newton will collect trash from canoes generously loaned by local residents.

  3. In addition to picking up trash, volunteers in Waltham will remove invasive weeds, including includingCharles River Cleanup garlic mustard and Japanese knotweed, from the banks of the Charles. Invasive species destroy aquatic habitat, crowd out native wildlife, and can negatively impact water quality. Removing invasive species is hard work, and these volunteers will certainly be a big help with this ongoing effort!

  4. The Earth Day Charles River Cleanup inspires volunteers to continue environmental stewardship beyond this day of service. Cleanup volunteers work year round to protect the Charles River. They remove invasive water chestnuts in the Charles River during the summer, collect water quality data monthly, and advocate for good environmental policies.

About Charles River Watershed Association:

One of the country's oldest watershed organizations, Charles River Watershed Association (CRWA) was formed in 1965 in response to public concern about the declining condition of the Charles. Since its earliest days of advocacy, CRWA has figured prominently in major clean-up and watershed protection efforts, working with government officials and citizen groups from 35 Massachusetts watershed towns from Hopkinton to Boston. Initiatives over the last fifty years have dramatically improved the quality of water in the watershed and fundamentally changed approaches to water resource management.
