Questions
Does California, MO have lead pipes?
None are confirmed, but California PWS still lists 373 service lines as unknown material.
Who supplies water to California?

How do I check whether my California home has a lead service line?
Search your address on California PWS's service line inventory map. You can also scratch the pipe where water enters your home: lead is soft, dull gray, scratches to shiny silver and doesn't attract a magnet.
When will lead pipes in California be replaced?
EPA's Lead and Copper Rule Improvements require most systems to replace lead and galvanized-requiring-replacement lines by December 31, 2037. Ask California PWS whether your street is scheduled and whether it covers the private side.
