Lead Service Lines in Green River, WY

Green River serves about 13,900 residents through 10 water systems. The largest utility is the City of Green River, which supplies water to roughly 10,500 people.

What we know about lead service lines here

Lead service lines are pipes that carry water from the main water line under the street into a home. They're a direct pathway for lead to enter drinking water.

In Green River, no lead service lines have been identified in publicly available data from the water utilities serving the area. This is good news—but it's important to understand what this means and what it doesn't.

The data gap

The utilities here have not reported finding lead service lines, and none have reported galvanized steel pipes (which can also contain or corrode into lead). However, many water systems nationwide, including some in Wyoming, haven't completed a full inventory yet. The absence of reported lead lines doesn't guarantee your home doesn't have one—it may mean the survey isn't finished, or records are incomplete, especially for homes built before 1986.

What to do about your own home

If your home was built before 1986, there's a higher chance it has a lead service line. Even if your utility reports low or zero lead lines, you can take steps to protect your family:

  • Contact your water utility to ask about your specific property. They may have records showing what type of pipe serves your home.
  • Get your water tested. A basic lead test costs $20–50 and tells you whether lead is actually present in your tap water right now.
  • Use cold water for drinking and cooking. Hot water leaches lead more readily from pipes.
  • Run the tap for 30 seconds each morning before using water for drinking or cooking, to flush out water sitting in pipes overnight.

If testing reveals lead above 15 ppb (parts per billion), contact your utility immediately and consider a certified water filter while a permanent fix is arranged.

Next steps for residents

  • Call or visit your water utility's website to ask whether your address has a lead service line on file
  • Request a free or low-cost water test through your utility or county health department
  • If your home was built pre-1986 and you're pregnant or have young children, ask your pediatrician about lead screening

Common questions

Does Green River have lead in the water?

No lead service lines have been reported by utilities in Green River. However, data may be incomplete, especially for older homes. The best way to know if your home is affected is to contact your water utility or get your water tested.

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

Contact your water utility with your address—they may have records. You can also hire a plumber to inspect the pipe where it enters your home, or scrape a small area of the pipe; lead is soft and will show a bright metal color underneath.

Is it safe to drink the tap water in Green River?

Green River's utilities test water regularly and report results to the public. If you're concerned about your home specifically, especially if it's older, a water test is the most reliable way to know.

What should I do if my water tests positive for lead?

Contact your water utility immediately. Use only cold water for drinking and cooking until the issue is resolved, run taps for 30 seconds before use, and consider a certified lead-reducing filter. For health concerns, talk to your doctor or call the CDC.
