A Victory for Clean Water: Citizen Science Data Leads to Change
June 1, 2017
For years, the Mystic River Watershed Association (MyRWA) and its volunteers have helped to document water pollution problems in the Town of Belmont. This week, that hard work paid off.
The U.S. Environmental Protection Agency (EPA) has issued an Administrative Order on Consent with the Town of Belmont over years of water quality damages. Over the next five years the town has agreed to make a significant investment in repairs to its storm water system, which is discharging pollutants, including human sewage, into waters of the Mystic River watershed. We congratulate Belmont on their commitment to improve water quality to tributaries to Alewife Brook.
This is a success story for citizen science and for non-profit environmental collaboration with government agencies. Data acquired by MyRWA volunteers and shared with EPA was key to making progress. This has been a group effort---from the dozens of volunteer monitors who go out each month to collect samples, to the tireless work of others like Roger Frymire, who spent countless hours finding sources of pollution in the Alewife Brook area.
Since 2000, volunteers through the MyRWA's Baseline Monitoring Program have generated water quality data that is shared with state and federal agencies. Each year the EPA in conjunction with MyRWA issues a water quality report card for the Mystic River watershed.
The 2015 water quality report card for the Belmont area tells the story: Alewife Brook earned a D grade with 50% compliance with boating and swimming standards for bacteria; Little River a D- grade at 44% compliance; and Winn's Brook an F grade at 33% compliance.
One powerful aspect of the Baseline Monitoring Program is that it is poised to document success as well as problems. As infrastructure repairs are made in Belmont, we fully expect these grades to improve. We look forward to documenting and celebrating water quality improvements to Alewife Brook, Little River, Winn's Brook, Wellington Brook---and the Mystic River itself---over the next five years!
Congratulations and thanks to everyone who continues to work with us for protecting clean water.
