Systems that also serve other counties are counted in full. Your water bill names your utility.

What to do if your line is lead or unknown

  1. Check the pipe where water enters your home.
  2. Use a filter certified to NSF/ANSI 53 for lead for drinking and cooking.
  3. Test your water, often free through the utility.
  4. Ask your utility about free or discounted replacement; most lines must be replaced by December 31, 2037.
