Lead service line data on this page: Marblehead Water DEPT. (MWRA).

UCMR 5 is a one-time EPA monitoring program, not a compliance determination. The values shown are the highest single sample result at any of the system's sampling points; one result above 4.0 ppt does not mean the system violates the PFAS rule, which is judged on running annual averages under separate compliance monitoring. Results describe the public water system, not an individual home.

In April 2024 EPA set enforceable limits (MCLs) of 4.0 ppt each for PFOA and PFOS, plus 10 ppt for PFHxS, PFNA and HFPO-DA (GenX) and a Hazard Index for mixtures, with compliance based on a running annual average at each sampling point and due in 2029 (EPA ↗). In May 2026 EPA proposed letting systems request two more years for PFOA/PFOS (to April 2031) and rescinding the PFHxS, PFNA, GenX and Hazard Index limits (EPA: extension proposal ↗ · EPA: rescission proposal ↗). These are proposals, not final rules, as of the date this page was built.

What to do next

Confirm with your utility. Inventories change as lines are inspected and replaced. The utility's official map and customer service line are the authoritative source.
If your status is unknown, many utilities ask customers to report what they see where the water pipe enters the building. EPA's Protect Your Tap guide explains how to check.
Consider testing. EPA: “Since you cannot see, taste, or smell lead dissolved in water, testing is the only sure way of telling whether there are harmful quantities of lead in your drinking water.” Your utility or state health department can point you to certified laboratories.
Use cold water. EPA: “Use only cold water for drinking, cooking and making baby formula. Remember, boiling water does not remove lead from water.”
Filters. EPA: “If you use a filter, make sure you use a filter certified to remove lead.” See EPA's consumer tool for filters certified to reduce lead.
