Lead Service Line Information for MO AMERICAN TRI STATE
What you need to know about lead pipes in your water system
MO AMERICAN TRI STATE serves approximately 8,680 people in Missouri. The water system draws from groundwater sources.
Current inventory status: As of our last update, this utility has not yet completed a public inventory of lead service lines—the pipes that connect homes to the water main. This is important information for your home and family, so here's what that means for you.
Why this matters
A lead service line is a direct pathway for lead to enter your drinking water. Lead can pose health risks, especially for young children and pregnant people. Even if your water system hasn't published an inventory yet, there may be lead service lines in the distribution area—particularly in homes built before 1986, when lead pipes were still common.
What the utility should be doing
Federal law (the Lead and Copper Rule) requires water systems to inventory all lead service lines and develop a replacement plan. The timeline depends on your system's size and when it was required to start. Utilities must make their inventory publicly available and update it regularly as they identify or replace lines.
How to find out about your home
Contact MO AMERICAN TRI STATE directly. Ask them:
- Whether your street or address area has been surveyed for lead service lines
- If your home was built before 1986 (higher risk for lead pipes)
- What their current replacement plan and timeline are
- How to request a free water test or test kit
You can also request their lead service line inventory and replacement plan. Utilities are required by law to provide this information.
Test your water
If you're concerned about lead at your tap, the EPA and CDC recommend testing. Your utility may offer free tests, or you can contact a certified lab. Flushing your tap before using water for drinking or cooking can reduce lead levels from service lines.
Next steps for residents
- Contact the utility at their main office number to ask about lead service lines on your street or at your address
- Request a free water test or ask where to get one
- Flush your tap for 30 seconds before using water for drinking or cooking
- Check the CDC website for guidance on reducing lead exposure in your home

Frequently asked
Does my water system have lead service lines?

How do I know if my house has a lead pipe?

Is it safe to drink water from a lead service line?
Lead service lines can release lead into drinking water. If you're concerned, use a certified water filter rated for lead, let tap water run 30 seconds before use, or use bottled water for drinking and cooking.
