Lead Service Line Compliance in Pennsylvania

Pennsylvania's 7,303 water systems serve roughly 12.6 million people. Under the EPA's Lead and Copper Rule Revisions (LCRR), all utilities must locate and report their lead service lines—pipes that connect homes to the water main—by October 2024.

What Pennsylvania utilities reported

As of October 2024, Pennsylvania's water systems have submitted their lead service line inventories to the state's primacy agency, the Department of Environmental Protection (DEP). These reports form the legal record of what each utility knows about lead pipes in its service area.

The data shows that across the state's systems, a significant portion of lines remain classified as unknown. This is typical for older water systems that lack detailed records of pipe material from decades past. Unknown status does not mean lead is present—it means the utility has not yet confirmed the material through direct inspection, permit records, or other documentation.

Why this matters for your home

If your utility's inventory lists your address as having a lead service line, you should know:

• A lead service line is not an emergency. Lead does not enter the water instantly or at high levels just because the pipe exists. Water chemistry and treatment matter greatly.
• Your utility must offer testing and mitigation options. Under LCRR, utilities that identify lead lines must help customers understand their options, which may include flushing, point-of-use filters, or partial/full replacement.
• Replacement is the only permanent fix. If your line is lead and you want it removed, talk to your utility about cost-sharing programs, financing, or state grants.

Finding your utility's status

Contact your local water utility directly to learn what they reported for your property. They can tell you:

• Whether your service line is listed as lead, copper, galvanized, unknown, or another material
• What testing or replacement programs they offer
• Whether state or federal funding is available to help cover costs

The DEP maintains compliance records and can direct you to your utility's most recent inventory report.

Next steps for residents

• Contact your water utility to ask what material your service line is made of and request a copy of their October 2024 inventory report.
• If listed as unknown, ask your utility what steps they are taking to confirm the material and what you can do to help (e.g., by allowing an inspection at your meter pit).
• If lead is confirmed, discuss testing, flushing, or replacement options with your utility; also visit the CDC lead and health page for health guidance.
• Look for state or federal funding. Check with your utility about LCRR and Infrastructure Investment and Jobs Act funding that may reduce your out-of-pocket replacement costs.

Whether your water contains lead depends on your utility's water chemistry treatment and your specific pipes.

Ask your utility what documentation they are gathering and whether you can allow an inspection of your meter pit or property records. Some utilities offer or require testing to narrow down the material." }, { "q": "Is it safe to drink water from a lead pipe?", "a": "Lead risk depends on water chemistry, how long water sits in the pipe, and the pipe's age and condition. Do not delay—contact your utility or visit the CDC website for guidance on testing and mitigation. A pediatrician can also advise on health concerns." }, { "q": "How much does it cost to replace a lead service line in
