Compliance
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
Not in this recordDisinfection by-products weren't monitored in this dataset
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
A federal limit (an MCL or action level) is an enforceable legal cap; a health goal is often stricter. Meeting the limit is a compliance fact, not a health clearance, and PurityMap publishes no overall compliance verdict.

Where does FOXBORO WATER DEPARTMENT get its water?
FOXBORO WATER DEPARTMENT is on record as drawing from groundwater. The source shapes which contaminants matter most for this system.
What does FOXBORO WATER DEPARTMENT's monitoring record show?
PurityMap's record for FOXBORO WATER DEPARTMENT holds 31 findings: 2 above a reference, 2 detected within the reference, 1 detected with no limit and 26 not detected, from 31 evidence records.

Is FOXBORO WATER DEPARTMENT's water safe to drink?
PurityMap does not issue a safety verdict. It publishes FOXBORO WATER DEPARTMENT's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.
How current is this FOXBORO WATER DEPARTMENT data?
The latest published record for FOXBORO WATER DEPARTMENT is dated 2026-09-16. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.
Does this assessment represent my home's tap water?
No. It is assessed at the water-system level from FOXBORO WATER DEPARTMENT's own monitoring. It does not cover the service line to your building or the plumbing inside it, which can add lead and other metals after the water leaves the system. A tap test is the way to know what reaches your glass.
What contaminants were detected in FOXBORO WATER DEPARTMENT?
Perfluorooctanesulfonic acid (PFOS), Perfluorooctanoic acid (PFOA), Perfluorobutanesulfonic acid (PFBS), Perfluorohexanoic acid (PFHxA) and Perfluoropentanoic acid (PFPeA) were detected in this record. Each finding shows its measured value, its reference and its source on this page.
What should I do if I'm concerned about PFAS in FOXBORO WATER DEPARTMENT's water?
Start with what the record shows: the PFAS findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific PFAS compounds in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.
