Brockton's water mostly comes from a pond 10 miles outside the city. Unfortunately, the pond water usually turns green in the summer over its entire western half.

The city has state-of-the-art chemical treatment for making water crystal clear and safe at your faucet. And so far, so good. However, this year, the city was ordered to stop using this water supply whenever the green color is caused by cyanobacteria. This may lead to more restrictions on outdoor water use and/or higher water bills. Disruptions, emergency changes, and other risks might be conceivable. Please help us advocate for a more sustainable water supply.

How did the problem start?
Brockton originally started using this pond water after a special State law passed in a drought emergency 50 years ago. The Town of Whitman was also allowed to use this water. Politicians let the law stand because it was convenient. However, taking green pond water from small towns is no longer sustainable, and now the urgency is high.
Why now?
On March 22, 2017, Brockton received an order from the Massachusetts Department of Environmental Protection to stop using this green water, for treatment and distribution to the public, in certain specific cases. This has restricted the Brockton Water Commission's ability to make local decisions for balancing public interests.
Why change?
A better option is available. The Massachusetts Water Resources Authority (MWRA) provides water from Quabbin Reservoir to millions of Massachusetts residents, and has plenty of capacity to add Brockton. The city would then have enough water for all current and future needs. The water supply would become independent of this known Environmental Protection issue that the city cannot control.
What should I do?
Join with us to deliver the simple message of No Green Water to the decision makers at Brockton City Hall. Express your support for MWRA as Brockton's future water supply. You can attend the public meetings of the Brockton Water Commission or work with the Mayor's office on water supply issues.
Is this website a public health alert?
No. In the event of a confirmed health issue or other water emergency, the Brockton Emergency Management Agency will contact you through their CodeRED service.
Does the city have a statement about water safety?
Yes, it is available on the Brockton Drinking Water Report website.
Is pond water consumption part of the reason that the water turns green?
Yes, according to the Sustainable Water Management Initiative Report prepared for the Department of Environmental Protection by independent ecological consultants, if this consumption stopped, then "In Monponsett Pond, improved water quality would likely be significant, yet due to continuing Phosphorus loading issues unrelated to Brockton Water System operations, water quality impairments due to algae blooms ... would remain in place." Other cited issues include agricultural lands, overland runoff, septic systems, and atmospheric loading.
