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

Ask Medina Co/Northwest Pws 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. Why sampled homes are the worst-case ones is in the guide to reading the number. Size matters more than most people expect: small vs large water systems.
