Your move
Look up your address in Swartz Creek, City Of's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask Swartz Creek, City Of whether it covers that cost before hiring anyone - many utilities now do.

What a 90th-percentile result does and does not tell you: how to read a lead result. A zero today does not rule out a jump later - the rules are tightening in 2027.
