Your move
Look up your address in Mount Saint Marys University's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask Mount Saint Marys University 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.
