EPA records for PEQUANNOCK TWP WATER DEPARTMENT • Updated October 2026
Grade B — based on EPA compliance records, lead testing and PFAS monitoring
PEQUANNOCK TWP WATER DEPARTMENT is in good standing with EPA, with only minor deductions for monitoring paperwork, low-level PFAS or historical readings near a limit.
Yes — by EPA's records Pompton Plains, NJ tap water is safe to drink and earns a B. The grade rests on lead at 5.1 ppb (90th percentile) — under the 15 ppb action level but above 5 ppb. Lead from your own service line or plumbing is the main risk city-level data cannot see, so homes built before 1986 should still test at the tap.

PEQUANNOCK TWP WATER DEPARTMENT's most recent Lead and Copper Rule result (2025-07-01 to 2025-12-31) was 5.09 ppb at the 90th percentile, below EPA's 15 ppb action level. Because lead usually comes from service lines and household plumbing, homes built before 1986 should still test at the tap.
No. None of the 116 UCMR5 PFAS results for PEQUANNOCK TWP WATER DEPARTMENT (2024-01-02 to 2024-10-29) were at or above the reporting limit of roughly 3–5 ppt.
PEQUANNOCK TWP WATER DEPARTMENT has 33 violations on file since 2016: 0 health-based in the last five years and 12 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
PEQUANNOCK TWP WATER DEPARTMENT reports purchased surface water as its primary source and serves about 14,010 people (EPA PWSID NJ1431001).
Optional but sensible. The findings on this page are below federal limits; an NSF-certified pitcher or under-sink filter handles lead and improves taste.

EPA Lead and Copper Rule 90th-percentile results reported by PEQUANNOCK TWP WATER DEPARTMENT
Below the action level, but detectable. In the most recent monitoring period on file (2025-07-01 to 2025-12-31), 90% of the homes PEQUANNOCK TWP WATER DEPARTMENT sampled had lead at or below 5.09 ppb.
EPA's action level is 15 ppb (dropping to 10 ppb under the 2024 Lead and Copper Rule Improvements). There is no safe level of lead; the 90th-percentile figure describes the system, not your tap — homes with lead service lines or pre-1986 plumbing can be higher.
| Monitoring period | Lead 90th percentile | vs 15 ppb action level |
|---|---|---|
| 2025-07-01 → 2025-12-31 | 5.09 ppb | Below the action level, but detectable |
| 2025-01-01 → 2025-06-30 | 4.64 ppb | Well below the 15 ppb action level |
| 2024-07-01 → 2024-12-31 | 3.6 ppb | Well below the 15 ppb action level |
| 2024-01-01 → 2024-06-30 | 3.52 ppb | Well below the 15 ppb action level |
| 2023-07-01 → 2023-12-31 | 3.56 ppb | Well below the 15 ppb action level |
| 2023-01-01 → 2023-06-30 | 8.71 ppb | Below the action level, but detectable |

EPA UCMR5 monitoring, 2024-01-02 to 2024-10-29 · 116 PFAS results at entry points to the distribution system
No PFAS detected. None of the 116 UCMR5 PFAS results for PEQUANNOCK TWP WATER DEPARTMENT were at or above the method reporting limit. Reporting limits are about 3–5 ppt, so “not detected” means below that threshold — not proven zero.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 4 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 4 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 4 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 4 | < 3 | 3 ppt | hazard index only |
“< 4 ppt” means below the laboratory reporting limit, not zero. ppt = parts per trillion (ng/L). Results are for finished water leaving the treatment plant.

EPA Six-Year Review 4 compliance samples for PEQUANNOCK TWP WATER DEPARTMENT · finished water only · dated data, released 2024
These are the regulated-contaminant samples PEQUANNOCK TWP WATER DEPARTMENT reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Total trihalomethanes (TTHM), Haloacetic acids (HAA5) are flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 190 detects | 0 µg/L | ND | 10 µg/LMCL | Not detected |
| Nitrate (as N) | 13 | 2.926 mg/L | 5.2 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 3830 detects | 0.07 mg/L | 0.15 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 19 | 1.111 µg/L | 2.1 µg/L | 100 µg/LMCL | Within MCL |
| Total trihalomethanes (TTHM) | 145 | 47.974 µg/L | 129 µg/L | 80 µg/LMCL (LRAA) | 14 single samples over MCL; average within limit |
| Haloacetic acids (HAA5) | 145126 detects | 25.679 µg/L | 78.3 µg/L | 60 µg/LMCL (LRAA) | 8 single samples over MCL; average within limit |
| Lead (tap samples) | 185124 detects | 3.719 µg/L | 69 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 202193 detects | 112.114 µg/L | 743 µg/L | 1300 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
Averages count non-detects as zero. TTHM and HAA5 limits are locational running annual averages, so a single high sample is not a violation — we grade those on the average only. Lead and copper rows are individual tap samples and are shown for context; compliance (and our score) uses the 90th-percentile result above. LRAA = locational running annual average; ND = not detected.

A point-of-use (under-sink) system typically runs $200-$600 installed; whole-house treatment $1,000-$3,000+ depending on flow and what has to come out. Tell us where you are and a certified water-treatment installer serving Pompton Plains will follow up - no obligation.
Surface-water systems draw from rivers, lakes or reservoirs and must filter and disinfect, which is why disinfection byproducts (TTHM, HAA5) are the readings to watch.
How to test your tap water and the treatment options that actually fit Pompton Plains homes
The most reliable way to know what is actually coming out of your tap is a certified mail-in lab test. City-wide EPA data (like the report above) reflects the water leaving the treatment plant, but contaminants such as lead and copper can be picked up from your own service line and household plumbing — so the water at your Pompton Plains faucet can differ from the system average. A state-certified lab measures dozens of contaminants at once with results you can trust; you can also find one near you through the EPA's certified-lab list at epa.gov/dwlabcert. Hardware-store test strips are cheaper and instant, but they only screen for a few basics (chlorine, hardness, pH, and a rough lead pass/fail) and are far less accurate — treat them as a first look, not a diagnosis.
Match the treatment to what your test finds. Reverse osmosis (RO) removes the widest range of contaminants — lead, arsenic, nitrate, PFAS, and dissolved solids — which makes an under-sink reverse osmosis system the most thorough choice for Pompton Plains households with heavy-metal or PFAS concerns. If your main issue is taste, odor, or chlorine, an activated carbon filter (pitcher, faucet, or under-sink) is simpler and cheaper and handles chlorine and many organic compounds well, though carbon alone does not remove arsenic, nitrate, or most PFAS. NSF-certified pitchers rated for lead reduction are the easiest way to start today while you decide on a permanent setup.
