Lead Service Lines in Bentonville, AR

Bentonville's water system serves about 52,000 residents across four separate water utilities. Right now, there is no publicly reported data on how many lead service lines exist in the city.

What we know

Lead service lines are pipes that connect the water main (in the street) to your home. If your home was built before 1986, there's a higher chance your service line contains lead. The only way to know for certain is to have it tested or to check with your water utility.

Bentonville Water Utilities serves the vast majority of residents in the city (about 51,250 people). The other three systems—serving Walmart's Onley facility, Oak Hills Suburban Improvement District, and Greater Life Apostolic Church—are much smaller.

What's missing

None of the water systems in Bentonville have published their lead service line inventories yet. Federal law requires all community water systems to complete these inventories by October 2024, so data should become available soon. Until then, your best option is to contact your water utility directly and ask about your specific address.

What you can do now

Contact your water utility. Ask whether a lead service line is known to serve your home. Bentonville Water Utilities can tell you if they have records for your address. If you're on a smaller system, you may need to reach out to that utility instead.

Get your water tested. Even without a known lead service line, a simple water test can tell you if lead is present in your tap water. Many water utilities offer free or low-cost testing kits. Call your utility to ask.

Consider a filter. If testing shows lead in your water, a certified pitcher filter or faucet filter can reduce it. Look for NSF certification for lead removal (NSF Standard 42 or 53).

Next steps for residents

  • Call Bentonville Water Utilities at their customer service line and ask if lead service lines are documented for your address
  • Request a free water test kit from your utility or a local health department
  • Check your home's age — if built before 1986, a lead service line is more likely
  • Follow CDC guidance on reducing lead exposure while you investigate (linked below)

Common questions

Does Bentonville have lead in the water?

There is no confirmed lead contamination reported in Bentonville's water supply. However, lead service lines—if present—can introduce lead into water as it travels from the main to your home. Contact your water utility to find out if a lead service line serves your address.

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

Call Bentonville Water Utilities and provide your address; they may have records. If your home was built before 1986, it's more likely. The most certain way is to have a plumber inspect the pipe where it enters your home.

Is it safe to drink tap water in Bentonville?

Bentonville's water meets federal safety standards. If you're concerned about lead specifically, a water test can tell you if it's present in your tap water. Contact your utility for testing options.

When will Bentonville publish its lead service line inventory?

Water systems are required by federal law to complete lead service line inventories by October 2024. Check back with Bentonville Water Utilities for their published data.
