Millis publishes its own water results. Hardness and manganese deserve a different conversation from PFAS: each calls for the right test and a treatment choice matched to the result.
The official 2025 Consumer Confidence Report lists PFAS6 at 9.22 parts per trillion, with results from not detected to 11.50, and marks no PFAS6 violation against the Massachusetts limit of 20. Source.
Total hardness is listed at 90.23 parts per million as calcium carbonate, with a range of 47.50–168.00. This is a public-system result, not a measurement of every home. Source.
The report lists manganese at 86.13 parts per billion, with a range from not detected to 484.00. Because the range is wide, ask the Water Department about the result relevant to your supply and any current advice. 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.

COMMON QUESTIONS
Water questions in Millis
Where does Millis’s drinking-water information come from?
Millis publishes a Consumer Confidence Report for its public water system. Local source. Public-system reports do not describe every property’s taps or a separate private well.
Does Millis publish a single hardness reading for every home?
No. The 2025 Consumer Confidence Report gives a public-system hardness range of 47.50–168.00 parts per million as calcium carbonate. That range is not a measurement of every home’s taps. Local source.
Can this guide interpret a test result from my Millis 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.
