Boil water advisories in Massachusetts
We do not read this state's advisories
We read Massachusetts MassDEP's page and did not find a list of active advisories on it: it points to one at a different address instead. We do not read that list into this page, so open it directly for what it shows now. That is one page on one day, not a statement about what Massachusetts MassDEP publishes. Advisories may still be issued by your utility or your county directly.

The mass.gov page is a guide rather than a list: when we read it on 24 August 2026 it carried no table and no dates. It points to a separate MassDEP database of drinking water public health orders, and we read that database the same day — 21 order rows, with columns for the city or town, the order type, the date the order was issued, its status and the date it was terminated. Its own preamble says it lists all drinking water public health orders for the past calendar year, so it holds orders that have already been terminated as well as any still in force.
This is not a statement that your water is safe. We do not read this state's advisories, so this page cannot tell you whether one is in force. Your utility is the authority for your own water.

Questions about this page
- Does this page list every boil water advisory in Massachusetts?
- No. We do not read Massachusetts MassDEP's advisories into this page, so nothing on it is a list of what is in force. What this page carries instead is where those advisories are published and which water systems our own database holds.
- Where are boil water advisories for Massachusetts published?
- Massachusetts MassDEP publishes the guide this page links to first, and that guide points to a separate list at another address, which this page links as well. We do not read either of them into this page, so open the list directly. The mass.gov page is a guide rather than a list: when we read it on 24 August 2026 it carried no table and no dates. It points to a separate MassDEP database of drinking water public health orders, and we read that database the same day — 21 order rows, with columns for the city or town, the order type, the date the order was issued, its status and the date it was terminated. Its own preamble says it lists all drinking water public health orders for the past calendar year, so it holds orders that have already been terminated as well as any still in force.
- How many water systems does this page cover?
- Our database holds 387 public water systems in Massachusetts. That is a count of what is in our database, not a count of every public water system in the state. Advisories are counted by water system, keyed on the system's federal identifier, and never by the number of separate notices one system has been given.
- Is anything on this page a verdict about whether the water is safe?
- This is not a statement that your water is safe. We do not read this state's advisories, so this page cannot tell you whether one is in force. Your utility is the authority for your own water.
