Lead Service Lines in Alpharetta, GA

What you need to know

Alpharetta's water systems serve about 435,000 residents across 7 different utilities. The good news: there are currently no confirmed lead service lines reported in any of these systems.

That said, "no confirmed" doesn't mean "impossible." Lead service lines—pipes that connect the water main to your home—were commonly installed before 1986. If your home was built or connected before that year, your line might contain lead, even if your utility hasn't formally documented it yet.

Your water utility

Most Alpharetta residents get water from North Fulton County, which serves roughly 434,500 people. A handful of smaller utilities serve mobile home parks and private communities.

What "unknown" means

Many water systems haven't fully inventoried their service lines. That's not unusual—it's expensive and time-consuming. When a utility reports "unknown," it means they either haven't completed the inventory or haven't publicly shared the results. This doesn't indicate a problem; it just means less transparency for now.

What to do if you're concerned

Get your water tested. It's the most straightforward way to know what's actually in your tap water. Many local health departments and water utilities offer free or low-cost testing. Lead shows up quickly in test results—usually within a week.

If lead is detected, the next steps depend on the level:

  • For any detectable lead, run cold water from the tap for 30 seconds before drinking or cooking.
  • Consider a certified lead-removing filter (look for NSF/ANSI Standard 53).
  • Contact your water utility to ask about service line replacement programs or rebates.

Some utilities are starting to fund lead line replacement. Ask your water provider whether they have financial assistance available.

Next steps for residents

  • Test your water through your local health department or water utility.
  • Contact North Fulton County Water System (or your specific utility) to ask about their lead service line inventory and replacement programs.
  • Check your home's age. If it was built before 1986, your service line has a higher chance of containing lead.
  • Visit the CDC's water lead page for health guidance, especially if you have children or are pregnant.

Common questions

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

Your water utility may have records, but testing your water is the fastest way to know. If lead is detected, your service line or internal pipes likely contain lead. You can also ask your utility whether they've inventoried service lines in your neighborhood.

Is lead in tap water dangerous?

Lead exposure, especially for children, can harm development and learning. For health concerns, contact your pediatrician or the CDC. If your water tests positive, use a certified filter or run cold water for 30 seconds before drinking.

Does Alpharetta have lead in its water?

No confirmed lead service lines have been reported in Alpharetta's water systems. However, utilities don't always have complete inventories, so testing your home's water is the best way to be sure.

Can I get my lead service line replaced?

Some water utilities offer funding or rebates for lead line replacement. Contact North Fulton County Water System or your local utility to ask what programs they have available.
