Your move
Look up your address in New Carroll Water System's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask New Carroll Water System 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. Small systems behave differently: why small systems go over more often.
