Next steps for Baylis, IL
Look up your address in Baylis's service line inventory. If it says lead, galvanized or unknown, test your tap.

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. The lead result guide covers how utilities pick the homes they sample. Small systems behave differently: why small systems go over more often.
