Lead Service Line Compliance in Connecticut Water Systems

How Connecticut utilities are reporting on lead pipes

Connecticut's water systems serve nearly 2.9 million people across 2,297 public water utilities. These systems are required under the EPA's Lead and Copper Rule Revisions (LCRR) to inventory their lead service lines—the pipes that connect water mains to homes—and report their findings.

As of October 2024, Connecticut's utilities have submitted their initial inventory reports. The state Department of Public Health, which oversees water system regulation in Connecticut, has been reviewing these submissions to ensure compliance with EPA timelines and accuracy standards.

What the numbers tell us

Connecticut's reporting shows that across the state's utilities, there are currently 0 lead service lines classified as definitively present and 0 classified as unknown. This suggests either that inventories are incomplete, that utilities have conducted thorough surveys and found no lead service lines in their systems, or that reporting is still underway.

It's important to note: an "unknown" classification doesn't mean a lead service line is definitely there. It means a utility couldn't confirm the pipe material from available records or visual inspection. Many utilities rely on service line material records from when pipes were installed, municipal records, or contractor documentation—and some of those records are incomplete.

State oversight and next steps

Connecticut's Department of Public Health has enforcement authority over water utilities that fail to meet LCRR requirements. Utilities must submit updated inventories and reports on a set schedule. If you want to know your own home's service line status—which is separate from what your utility reports citywide—contact your local water utility directly and ask about your service line material.

The EPA has given utilities until October 2024 to submit initial inventories, with further sampling and updates required through 2027. Connecticut utilities are expected to continue refining their data as inspections and replacements happen.

Next steps for residents

  • Contact your water utility and ask about your home's service line material directly—don't wait for a citywide report.
  • Request a free water test if you're concerned; some Connecticut utilities offer this through their public health programs.
  • Check with your town's public health department if your water utility can't provide service line information.
  • Learn about treatment options (filters, flushing) at the CDC website if lead in water is a concern for your household.

Common questions

Does Connecticut have lead in its drinking water?

Lead in water typically comes from old service lines and household plumbing, not from the water source itself. Connecticut utilities have reported their lead service line inventories; contact your local water utility to learn about your home's specific service line material.

How do I find out if my house has a lead service line in Connecticut?

Call your local water utility and ask them to check your service line material in their records. They may also send someone to inspect the pipe where it enters your home or at the meter.

What should I do if my home has a lead service line?

Flush your cold-water tap for 30 seconds before drinking or cooking. Consider having your water tested by a certified lab. Your water utility or town health department can advise you on replacement programs or assistance available in your area.

Is bottled water safer than tap water if there's lead in my service line?

For infants, bottled water labeled as purified, distilled, or demineralized may be safer; consult your pediatrician. For others, proper flushing and certified water filters can reduce lead exposure. The CDC website has specific guidance by age.
