Compliance

1health-based violation in the last 10 years

From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.

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.

Questions

Frequently asked questions

Who does CHATHAM CO-NORTH serve?

CHATHAM CO-NORTH (PWS ID NC0319126) is a public water system serving 23,088 people in Chatham Co-north, North Carolina.

Where does CHATHAM CO-NORTH get its water?

CHATHAM CO-NORTH is on record as drawing from surface water. The source shapes which contaminants matter most for this system.

What does CHATHAM CO-NORTH's monitoring record show?

PurityMap's record for CHATHAM CO-NORTH holds 31 findings: 1 detected within the reference, 1 detected with no limit and 29 not detected, from 31 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.

Is CHATHAM CO-NORTH's water safe to drink?

PurityMap does not issue a safety verdict. It publishes CHATHAM CO-NORTH'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 CHATHAM CO-NORTH data?

The latest published record for CHATHAM CO-NORTH is dated 2026-10-15. 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 CHATHAM CO-NORTH'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 CHATHAM CO-NORTH?

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 CHATHAM CO-NORTH'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.
