Medfield’s groundwater system has documented iron, manganese and PFAS planning history. Use that background to ask better questions—not as proof that your current tap water has a problem.
The January 2024 Water System Master Plan describes five public groundwater wells and a treatment plant commissioned in 2023 to remove iron and manganese from Wells 3A and 4. Source.
The same plan reports historical PFAS6 averages since 2021 of 15.8 parts per trillion in raw Well 1, 18.7 in raw Well 2 and 17.8 in Main Street finished water. These historical averages were below the MA limit of 20, not current 2026 test results. Source.
A public-system result is not a test of a separate private well or every home’s plumbing. This page is background information, not a safety certification. For current restrictions or health advice, follow your water supplier and Board of Health.

Where does Medfield’s drinking-water information come from?
Medfield’s January 2024 master plan describes five public groundwater wells and an iron-and-manganese treatment plant commissioned in 2023. Local source. Public-system reports do not describe every property’s taps or a separate private well.
How recent are the Medfield PFAS figures in this guide?
They are historical averages summarized in the January 2024 Water System Master Plan, not current tap-water measurements. The town also publishes an annual water-quality report index. Local source.
Can this guide interpret a test result from my Medfield home?
No. The guide provides local background and provider information, not a safety certification or a system recommendation. For health questions about a test result, speak to a certified lab or your local board of health.
