So Where Does Boston’s Tap Water Come From?

Posted on July 1, 2011



The Quabbin and Wachusett Reservoir supply water to the local water departments in 51 communities. These two reservoirs supply us with about 200 million gallons of water a day. The water is naturally protected as 85% of the watershed (land around reservoirs) is covered by forest and wetlands. The rain and snow that fall on watersheds form streams which flow into the reservoirs. Although this process helps clean the water, it comes in contact with soil, rock, plants, and other matter.

Testing sites clean this water to produce the clean water that flows through your faucets. The Department of Environmental Protection (DEP) creates strategies to test and treat water in order to protect us from getting contaminated water. They state “watershed protection programs are very successful and greatly reduce the actual risk of contamination”.    

Tap water is safe to drink from and even has fluoride in it to protect us from oral cavities. If you have any questions or interest in learning more call us at the Mayors Health Line (617-534-5050) and check out relevant websites such as Department of Conservation and Recreation (DCR).
