Lead Service Lines in Stamford: What You Need to Know
AQUARION Water Company serves about 119,000 people in the Stamford area. Like many older water systems in Connecticut, your neighborhood may have lead service lines—the pipes that carry water from the main line under the street into your home.
Why this matters
Lead service lines are the most common source of lead in drinking water. Even small amounts matter: there is no safe level of lead exposure, especially for children under 6 and pregnant people. If your home was built before 1980, there's a meaningful chance your service line contains lead.
What AQUARION has inventoried
AQUARION-STAMFORD has not yet completed a public inventory of lead service lines in its system. The utility has not reported how many lead lines exist, how many remain unknown, or a timeline for full testing.
This is not unusual—many water systems are still in early stages of mapping their service lines. However, it means you cannot currently check a database to learn whether your specific address has a lead service line.
How to find out about your home
Contact AQUARION directly. Ask them:
- Whether your service line is lead, copper, galvanized, or unknown
- When they expect to complete their full inventory
- What they recommend for testing your water
You can also arrange a free water lead test through your local health department or a certified lab. A test tells you whether lead is actually entering your home right now—useful information regardless of what your service line is made of.
What happens next
Federal law requires all water utilities to identify and replace lead service lines. Congress allocated funding through the Bipartisan Infrastructure Law to help systems pay for replacements. AQUARION will eventually need to set a replacement schedule and share it publicly.
In the meantime, if you're concerned about lead in your water, there are steps you can take today: flush your tap before drinking, use cold water for cooking and baby formula (hot water holds more lead), and consider a certified filter if testing shows a problem.
Next steps for residents
- Contact AQUARION Water Company at their customer service line to ask about your service line status and water testing options.
- Request a free lead test from your local health department (Stamford Health Department) or a certified private lab.
- Flush your tap for 30 seconds before using water for drinking or cooking, as a temporary precaution.
- Visit the EPA's lead in drinking water page for detailed guidance on filters and replacement.

Frequently asked
How do I know if my home has a lead service line in Stamford?
Contact AQUARION Water Company directly—they can tell you what material your service line is made of. You can also look at your water bill or property records, though these are not always accurate. A certified plumber can also inspect your line.
Can I test my tap water for lead myself?
Yes. Contact your local health department (Stamford Health Department) for a free test, or hire a certified lab. Testing is inexpensive and shows whether lead is actually in your water right now.
If my service line is lead, do I have to replace it?
The water utility (AQUARION) is required by federal law to replace lead lines over time. If you own your home, you may be responsible for the portion on your property, but utilities often share costs or offer assistance programs—ask AQUARION about options.
Is my family's water safe right now?
The only way to know is testing. Even homes with lead service lines don't always have measurable lead in the water. If you're concerned, get your water tested and contact AQUARION about protective steps in the meantime.
