Lead service lines in Bryn Mawr, PA

What you need to know

Water in Bryn Mawr is served by 27 water systems. The largest—AQUA PA MAIN SYSTEM—serves about 822,600 people across the region. Together, these systems serve the area's 1,057,862 residents.

Lead service lines are pipes that carry water from the water main in the street to your home. If your home was built before the 1980s, there's a meaningful chance your service line contains lead. Lead can leach into drinking water, especially if water sits in pipes overnight or if the water is corrosive.

Pennsylvania requires water utilities to maintain an inventory of lead and galvanized service lines and to share that information with customers upon request. However, many utilities still have incomplete records—they may not know the full extent of lead lines in their service areas.

How to find out about your home

Your water utility has records about whether your service line is known to contain lead, is likely galvanized (which can corrode and release lead), or is unknown. Start by contacting your local water system. If you don't know which utility serves you, check your water bill or call your local government office.

When you reach out, ask specifically:

  • Does your system have records of my service line material?
  • If the material is unknown, what's the process to determine it or have it tested?

If records are incomplete or unavailable, you can arrange a professional inspection or have your water tested. Testing is especially important if you have young children or are pregnant.

Taking action

Even if your service line is lead-free, corrosion control matters. Ask your utility whether they add corrosion-control treatment to the water. This treatment helps prevent lead from leaching into your water.

If you discover or suspect a lead service line, the ultimate solution is replacement. Many utilities and state programs now offer grants or low-interest loans to help with the cost. Your water utility can point you toward available funding.

Next steps for residents

  • Contact your water utility and request their lead service line inventory records for your address.
  • Test your water through your utility or a certified lab if you're concerned about lead exposure.
  • Ask about corrosion control and whether your system treats water to minimize lead leaching.
  • Look into replacement programs if a lead line is confirmed; state and federal funding is increasingly available.

Common questions

How do I know if my house has a lead service line?

Contact your water utility and ask for their records of your service line material. If they don't have records, you can hire a plumber to inspect the line where it enters your home, or have your water tested. Homes built before the 1980s are more likely to have lead lines.

Is lead in drinking water dangerous?

Lead can harm brain development in children and cause other health problems. For specific health concerns, talk to your pediatrician or contact the CDC. Even small amounts of lead exposure can be a problem, especially for young children and pregnant people.

Can I remove lead from my drinking water myself?

Certain water filters certified for lead removal can help reduce lead in your tap water. However, the best long-term solution is replacing a lead service line. Your utility can recommend certified filters and may have lead line replacement programs.

What's the difference between a lead service line and a galvanized one?

Lead lines are made of lead metal; galvanized lines are steel coated with zinc. Both can release lead into water over time, especially in corrosive water. Your utility should know which material your line is made of.
