Gales Ferry Tap Water Quality Report

How Uranium is removed

Anion exchange — EffectiveUranium is anionic at typical pH; strong-base anion resin removes it well.
Reverse osmosis — Effective

Look for certification to NSF/ANSI 58.

How Trihalomethanes (a disinfection byproduct) is removed

Activated carbon filter — ConditionalRequires an NSF/ANSI 53 TTHM-certified carbon and adequate contact time; carbon adsorbs TTHM but breaks through over time. EPA's municipal BAT is GAC10/GAC20 with enhanced coagulation or softening.

Look for certification to NSF/ANSI 53.

How Radium is removed

Ion-exchange softener — EffectiveCation-exchange softening removes radium along with hardness; capacity is consumed by hardness.
Reverse osmosis — Effective

How Gross alpha particle activity (a screening measure) is removed

Reverse osmosis — EffectiveGross alpha is a screening measure for alpha-emitting radionuclides, including radium-226 and excluding radon and uranium. Where a utility also reports radium separately, the radium answer applies too.

Look for certification to NSF/ANSI 58.

Source: EPA 40 CFR 141.66(g) BAT — gross alpha particle activity (MCL 15 pCi/L)

Lead and copper from the upstream record — not counted (2)

These rows for SCWA, LEDYARD CENTER DIVISION come from the upstream record, not from EPA's lead-and-copper result, which is the evidence lead and copper are judged on. Each is shown as reported and is not counted as above or within a guideline, as a result, or as nothing detected. EPA's lead-and-copper result for this system

Detected in some samples (6)

SCWA, LEDYARD CENTER DIVISION's samples found these in some samples but not in most, so no level is on file for them. The share of samples each was found in is shown; it is not a concentration, and none of these is counted as above or within its guideline.

Dibromoacetic Acid (DBA): detected in some samples (11% of samples)
Radium 226: detected in some samples (33% of samples)
Total Coliform: detected in some samples (7% of samples)
Beryllium: detected in some samples (25% of samples)
Chloroform: detected in some samples (21% of samples)
Total Haloacetic Acids (HAA5): detected in some samples (13% of samples)

A positive total coliform result triggers a utility assessment. It is not an exceedance: EPA has set no health goal for total coliforms since April 2016, and any assessment or violation EPA records is listed with this system's violations.

Measured, no level on file (3)

These are properties of the water, not contaminants. SCWA, LEDYARD CENTER DIVISION measured them, and no level is on file.

Lead: EPA lead-and-copper result

Below the 15 ppb action level

EPA's lead-and-copper record for SCWA, LEDYARD CENTER DIVISION lists a 90th-percentile lead result of 2.2 ppb for the monitoring period Jan 1, 2025 – Dec 31, 2025, reported Dec 15, 2025, below the 15 ppb (0.015 mg/L) action level. EPA's health goal for lead is 0 ppb, and a 90th percentile does not describe every tap.

EPA SDWA data as of Jul 9, 2026 (2026 Q2), water system CT0720313. The action level is 15 ppb.

Understanding the Data

These are SCWA, LEDYARD CENTER DIVISION's own test results, not a city-wide average. The bar charts compare each detected level against EPA's Maximum Contaminant Level Goal (MCLG), a disinfectant's Maximum Residual Disinfectant Level Goal (MRDLG), or, for an analyte EPA sets no health goal for, its enforceable legal limit (MCL), and say which. Readings above either are shown by default and may require filtration; everything else the utility tested for is listed above, including the analytes it found nothing in.
