EPA records for TORRINGTON WATER COMPANY • Updated September 2026
Grade A — based on EPA compliance records, lead testing and PFAS monitoring
TORRINGTON WATER COMPANY has a clean recent record: no health-based violations in the last five years and no lead, PFAS or historical monitoring result that costs it more than a few points.
Yes — by EPA's records, Torrington's tap water earns a A: no health-based violations in five years, lead at 0 ppb (90th percentile) and no PFAS detected. Lead from home plumbing is the main remaining risk.
By EPA's records, yes. TORRINGTON WATER COMPANY earns a A: no health-based violations in the last five years, a lead 90th-percentile result of 0 ppb, and no PFAS detected in UCMR5 sampling. Lead from your own plumbing is the main risk city data cannot see.
TORRINGTON WATER COMPANY's most recent Lead and Copper Rule result (2024-01-01 to 2026-12-31) was 0 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 TORRINGTON WATER COMPANY (2024-01-03 to 2024-10-07) were at or above the reporting limit of roughly 3–5 ppt.
TORRINGTON WATER COMPANY has 3 violations on file since 2016: 0 health-based in the last five years and 0 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
TORRINGTON WATER COMPANY reports surface water as its primary source and serves about 37,915 people (EPA PWSID CT1430011).
Not on the strength of EPA's data for TORRINGTON WATER COMPANY. A filter still helps with taste and with lead from your own plumbing, which no city-level test can measure.

EPA Lead and Copper Rule 90th-percentile results reported by TORRINGTON WATER COMPANY
Well below the 15 ppb action level. In the most recent monitoring period on file (2024-01-01 to 2026-12-31), 90% of the homes TORRINGTON WATER COMPANY sampled had lead at or below 0 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 |
|---|---|---|
| 2024-01-01 → 2026-12-31 | 0 ppb | Well below the 15 ppb action level |
| 2026-01-01 → 2026-12-31 | 0 ppb | Well below the 15 ppb action level |

EPA UCMR5 monitoring, 2024-01-03 to 2024-10-07 · 116 PFAS results at entry points to the distribution system
No PFAS detected. None of the 116 UCMR5 PFAS results for TORRINGTON WATER COMPANY 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 TORRINGTON WATER COMPANY · finished water only · dated data, released 2024
These are the regulated-contaminant samples TORRINGTON WATER COMPANY 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 | 80 detects | 0 µg/L | ND | 10 µg/LMCL | Not detected |
| Nitrate (as N) | 82 detects | 0.014 mg/L | 0.056 mg/L | 10 mg/LMCL | Within MCL |
| Fluoride | 8 | 0.573 mg/L | 0.67 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 80 detects | 0 µg/L | ND | 100 µg/LMCL | Not detected |
| Uranium (combined) | 30 detects | 0 µg/L | ND | 30 µg/LMCL | Not detected |
| Radium-226/228 | 31 detects | 0.177 pCi/L | 0.53 pCi/L | 5 pCi/LMCL | Within MCL |
| Gross alpha | 30 detects | 0 pCi/L | ND | 15 pCi/LMCL | Not detected |
| Total trihalomethanes (TTHM) | 160 | 39.606 µg/L | 110 µg/L | 80 µg/LMCL (LRAA) | 3 single samples over MCL; average within limit |
| Haloacetic acids (HAA5) | 162161 detects | 29.691 µg/L | 78 µg/L | 60 µg/LMCL (LRAA) | 4 single samples over MCL; average within limit |
| Lead (tap samples) | 7115 detects | 2.361 µg/L | 88.4 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 71 | 55.438 µg/L | 226.3 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.

TORRINGTON WATER COMPANY · 10,164 service lines inventoried · Q2 2026 snapshot
TORRINGTON WATER COMPANY reports 126 service lines that are lead or galvanized-requiring-replacement (1.2% of the lines it has inventoried), plus 8,784 lines whose material is still unknown. A lead service line is the pipe between the water main and a building, so treated water can pick up lead after it leaves the plant — which city-level testing does not capture. Under EPA's Lead and Copper Rule Improvements, utilities must replace lead lines within 10 years starting in 2027.

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 Torrington 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 Torrington 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 Torrington 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.
