Lead Service Lines in Ashburn, VA

What we know about lead in Ashburn's water

Ashburn's water is served by four water systems, with Loudoun Water operating the main system that serves nearly all of the area's 334,923 residents. Current data shows no confirmed lead service lines in Ashburn's inventory.

That said, "no confirmed" is different from "none exist." Many older water systems across the country have incomplete records of what material their pipes are made from—especially in neighborhoods built before the 1980s. If your home was built before 1980 and you've never had your service line tested, there's a real possibility it contains lead, even if your utility's official count shows zero.

Why this matters

Lead service lines are the most common source of lead in drinking water. When water sits in a lead pipe overnight or over a weekend, lead can leach into it. This is especially true if your water is acidic or soft. Even low-level exposure over time can be harmful, particularly for young children and pregnant people.

The good news: lead in water is preventable and testable. If you know your service line is lead, or suspect it might be, there are straightforward steps to reduce exposure immediately.

What Loudoun Water has reported

Loudoun Water, which serves 334,808 residents in the Ashburn area, has not reported any known lead service lines in its current inventory. However, you can contact them directly to ask about your specific address and request a free or low-cost service line inspection—many Virginia utilities offer this.

The three smaller systems serving special facilities (a golf course, vineyards, and an event center) have minimal populations and serve non-residential customers.

Next steps for residents

  • Contact Loudoun Water at their customer service line to ask if your address is known to have a lead service line, and whether they offer free inspection or testing.
  • Request a service line material inspection if your home was built before 1980 or you don't know when your line was installed.
  • Test your water for lead if you're concerned. Many utilities offer free or discounted testing kits.
  • Check with your pediatrician or local health department if you have questions about health risks; they can assess your household's specific situation.

Common questions

Does Ashburn Virginia have lead in the water?

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

Contact Loudoun Water and ask about your specific address. Many homes built before 1980 have lead lines, even if they're not on the utility's official list. You can also request a free or low-cost inspection to find out what your service line is made of.

Is it safe to drink tap water in Ashburn VA?

Ashburn's tap water is regularly tested and meets federal safety standards. However, if your home has a lead service line, lead can enter your water while it sits in the pipes. If you're concerned, ask your utility about testing your water or contact your doctor.

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

Let water run for 30 seconds before drinking or cooking (flushes out stagnant water), use cold water for drinking and cooking, and have your water tested. Loudoun Water may offer replacement programs or rebates; contact them to ask about financial assistance.
