These are monitoring results collected under EPA's Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) at entry points, where treated water enters the distribution system; they are not tap-water samples. They are not compliance determinations: compliance with EPA's 2024 PFAS limits is judged on running annual averages of compliance monitoring, required from 2029, so a single UCMR 5 result at or above a limit is not a violation. “< MRL” means the compound was not quantified at EPA's minimum reporting level; it does not mean zero.
Water purchased from
- Nj American Water - Short Hills (NJ0712001)
Seller's highest results: PFOA 9.1 ppt · PFOS 6.1 ppt · HI 0.36 · detected: PFBA;PFBS;PFHxA;PFHxS;PFOA;PFOS;PFPeA - East Orange Water Commission (NJ0705001)
Seller's highest results: PFOA 13 ppt · PFOS <MRL · HI 0.32 · detected: PFHxS;PFOA
Seller results are the seller's own entry-point samples, not measurements of this system's water. This system's own samples (below) may reflect purchased water, its own sources, or both.
Compared with EPA's 2024 values
| Highest single result | Worst entry-point average* | Limit | |
|---|---|---|---|
| PFOA (ppt) | 44 | 36.95 | 4 |
| PFOS (ppt) | 5.7 | 4.95 | 4 |
| Hazard Index | 0.713 | 0.632 | 1.0† |
“<MRL” = every result for the compound was below its reporting limit. * Mean of all samples at each entry point with non-detects = 0 (EPA compliance convention; the Hazard Index also uses non-detects = 0); a screening comparison, not a formal running annual average. † Rescission proposed May 2026. PFOA/PFOS MCL 4 ppt (2024 NPDWR, in effect). PFHxS, PFNA, HFPO-DA (10 ppt each) and the Hazard Index (1.0) are 2024 NPDWR values; EPA proposed rescinding them on 18 May 2026 (comment period closed 20 Jul 2026).
Compared with New Jersey standards
| Highest single result | Worst entry-point average* | New Jersey | |
|---|---|---|---|
| PFNA (ppt) | 0 | 0 | 13 |
| PFOA (ppt) | 44 | 36.95 | 14 |
| PFOS (ppt) | 5.7 | 4.95 | 13 |
Sum standards add the listed compounds within each sample (non-detects = 0). State compliance is normally judged on averages over time; these are screening comparisons.

Left-censored Kaplan–Meier statistics (Helsel 2005; Helsel & Lee 2006, NADA for R). Units: ppt; lithium µg/L. Each compound has one reporting limit, so the Kaplan–Meier mean equals the upper mean bound (non-detects at the MRL); the lower bound sets non-detects to 0. “<MRL” = the percentile falls below the reporting limit and cannot be estimated. These describe this system's UCMR 5 samples, not population estimates.
