The Massachusetts Water Resources Authority (MWRA) treats the water we receive in Framingham at its Carroll Water Treatment Plant in Marlborough, MA before it arrives at our homes by traveling through the MetroWest Water Supply Tunnel.

It then travels through Framingham’s local pipes, serving each street, and is eventually carried into buildings through each owner’s private water service connections.
Lead Testing
The department participates in the Federal Lead Sampling program which requires scheduled sampling at determined locations throughout Framingham. The MWRA offers this list of laboratories which offer testing for lead in your water. The water supplied to you by the MWRA and the town’s water main system is lead free. However, once it enters your own private service, it could come in contact with:
  • Brass fixtures
  • Soldering
  • Unknown lead piping
The benefit of having your water tested is that you can detect whether you have any lead in your own pipes or fixtures. It is not mandatory and it is up to the homeowner to pay for the test (average price = $25).
