What's in Hampton, VA tap water
2 contaminants in Hampton, VA's water sat at or above a federal limit, led by PFOS (Perfluorooctane sulfonic acid) at 1.4x the limit.
- !2 contaminants at or above a federal limit — worst is PFOS (Perfluorooctane sulfonic acid) at 1.4x
- !1 contaminant within 20% of a limit
- !22 of 27 core regulated contaminants reported — 5 never appear in this report
- ✓No open federal violations
+How this score is calculated
Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.
- −35 contaminants at or above a federal limit
- −4 contaminants within 20% of a limit
- −0 open health-based violations
- −0 open monitoring / reporting violations
- −0 health-based violations resolved in the last 5 years
- −0 core regulated contaminants never reported (22/27)
A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.

- PFOS (Perfluorooctane sulfonic acid)1.4× the federal limit5.6 ng/L · limit 4 ng/L
Linked to cancer, thyroid disease, and immune effects; the EPA set an enforceable limit of 4 parts per trillion.

Effective and necessary, but high residual levels can cause taste and odor issues; the EPA caps the residual disinfectant level.

PFAS — EPA UCMR5 (2023–2025)
1 PFAS compound above EPA limits in Hampton, VA
The EPA finalized the first-ever federal drinking-water limits for six PFAS compounds in April 2024. These numbers come straight from EPA's UCMR5 lab dataset — every U.S. system serving more than 3,300 people tested every PFAS sample at an entry point to its distribution system. PFAS not listed below were either tested and not detected, or not yet sampled.
