What to do in your house
Test your own tap with a certified lab first-draw sample; St. Louis, MO may offer free or low-cost kits through the utility.

Ask Cs Christopher Creek Haven whether it covers that cost before hiring anyone - many utilities now do.
These figures describe homes the utility sampled, not your tap. Only your service line record or a test of your own water answers the question for your house. What a 90th-percentile result does and does not tell you: how to read a lead result. Size matters more than most people expect: small vs large water systems.
