DULLES AIRPORT Lead Service Line Inventory
What you need to know
Dulles Airport's water system serves approximately 76,500 people. Like all US public water systems, it is required by federal law to test for lead and maintain an inventory of lead service lines—the pipes that connect the water main to individual buildings.
Current inventory status: Dulles Airport has not yet completed or published a lead service line inventory. This means the utility has not yet identified how many lead service lines (if any) are in its service area, or shared that information publicly.
Why this matters
A lead service line is the most common source of lead in drinking water. Even low levels of lead can be harmful, especially to children and pregnant people. If your building has a lead service line, water can pick up lead as it travels through the pipe—even if the water leaves the treatment plant lead-free.
Federal regulations under the Lead and Copper Rule require all water utilities to:
- Locate and document all lead service lines
- Notify customers of known or suspected lead service lines
- Develop a plan to replace them
What Dulles Airport should do next
The utility is required to complete its lead service line inventory and make it available to customers. You can ask about this by contacting the system directly.
Once an inventory is published, you'll be able to find out:
- Whether your address has a known or suspected lead service line
- What testing results the utility has found
- Whether a replacement program is available
- What steps you can take to reduce lead exposure
Next steps for residents
- Contact Dulles Airport's water system and ask for the status of their lead service line inventory and when it will be completed.
- Request information about your specific address—ask whether a lead service line has been identified at your building.
- Consider water testing if you're concerned about lead. Contact your utility or a certified lab for guidance.
- Visit the CDC website for information on lead health risks and steps to reduce exposure.

Frequently asked
How do I know if my home has a lead service line?
Contact your water utility and ask whether your address is in their lead service line inventory. You can also hire a licensed plumber to inspect your water lines, or send a water sample to a certified lab for testing.
Is lead in water dangerous?
Yes. Lead can harm the brain and nervous system, especially in children and pregnant people. The CDC recommends testing your water if you're concerned. Visit cdc.gov/lead for health information.
Can I remove lead from my drinking water?
Yes. Point-of-use filters (like pitcher filters or faucet attachments) and reverse osmosis systems can reduce lead, but they require regular maintenance. Ask your utility about which products are certified to work in your area.
Why hasn't my water system finished its lead inventory yet?
Many utilities are still working to locate and document all lead service lines, which is a large undertaking. Recent federal funding through the Bipartisan Infrastructure Law is helping systems complete these inventories faster. Contact your utility to ask for a timeline.
