Matched to what EPA's records actually show for NORWICH PUBLIC UTILITIES (grade C, 71/100) — not to what sells.
EPA SDWIS/ECHO 2026Q2 · UCMR5 (2023–2026, July 2026 release) · SYR4 six-year review 2012–2019 · Full Norwich water quality report · Methodology
Reverse osmosis (PFAS at or above the federal limit). EPA's UCMR5 sampling of NORWICH PUBLIC UTILITIES detected PFBS, PFHxS, PFOA, PFOS, PFPeA, with PFOA or PFOS at or above the 4 ppt federal MCL. RO removes both long- and short-chain PFAS; a carbon block certified for PFOA/PFOS is the lower-cost option for PFOA/PFOS-only detections, provided cartridges are changed on schedule.
Based on EPA records for NORWICH PUBLIC UTILITIES, yes: reverse osmosis (pfas at or above the federal limit) is the first fix (see the evidence table above).
Reverse osmosis (NSF/ANSI 58). It is the only common household technology that removes PFAS at the levels found.
NORWICH PUBLIC UTILITIES's latest Lead and Copper Rule 90th-percentile result was 0 ppb (2025-01-01 to 2025-12-31), below the 15 ppb action level. Lead enters from service lines and home plumbing, so test at the tap if your home is older.
Yes. UCMR5 sampling (2023-05-23 to 2024-03-07) detected PFBS, PFHxS, PFOA, PFOS, PFPeA, with PFOA or PFOS at or above the 4 ppt MCL. RO and PFOA/PFOS-certified carbon filters reduce them.
Look for: NSF/ANSI 58 (RO) or NSF/ANSI 53 with a PFOA/PFOS claim (formerly NSF P473)

| Evidence | Result | EPA limit | Period | Source |
|---|---|---|---|---|
| PFBS | 6 ppt (max of 10 results, 3 detects) | no federal MCL | 2023-05-23 → 2024-03-07 | EPA UCMR5 (July 2026 release) |
| PFHxS | 12.5 ppt (max of 10 results, 2 detects) | 10 ppt | 2023-05-23 → 2024-03-07 | EPA UCMR5 (July 2026 release) |
| PFOA | 6.7 ppt (max of 10 results, 3 detects) | 4 ppt | 2023-05-23 → 2024-03-07 | EPA UCMR5 (July 2026 release) |
| PFOS | 16.2 ppt (max of 10 results, 3 detects) | 4 ppt | 2023-05-23 → 2024-03-07 | EPA UCMR5 (July 2026 release) |
| PFPeA | 3.9 ppt (max of 10 results, 1 detect) | no federal MCL | 2023-05-23 → 2024-03-07 | EPA UCMR5 (July 2026 release) |
Look for: NSF/ANSI 53 with a TTHM/VOC claim, or NSF/ANSI 42 for taste
Disinfection byproducts averaged above 80% of the EPA limit in NORWICH PUBLIC UTILITIES's 2012–2019 monitoring. Carbon block filters reduce TTHM and HAA5 along with the chlorine taste that comes with them; any RO system's carbon stages do the same.
| Evidence | Result | EPA limit | Period | Source |
|---|---|---|---|---|
| Total trihalomethanes (TTHM) | 65.679 ug/L (average of 234 samples) | 80 ug/L | 2012–2019 | EPA SYR4 six-year review |
Look for: Certified lab (Tap Score)
Utility data describes water leaving NORWICH PUBLIC UTILITIES. Lead, copper and some PFAS enter between the main and your faucet, so a mail-in lab test is the only way to know what your household actually drinks — and the cheapest way to avoid buying a filter you do not need.
Rows are the contaminants EPA data actually flags for Norwich. ✓ removes (when certified) · ◐ only specific certified models or media · ✗ does not remove.

Cost ranges are typical retail prices, not quotes. Removal marks describe the filter class when certified for that contaminant — always check the NSF/ANSI listing of the exact cartridge. Full pitcher vs under-sink vs faucet comparison →
A certified mail-in lab test shows exactly what's in your water — pfas plus dozens of other contaminants — with EPA-grade accuracy. Know your real levels before spending on a filter.
