Your move
Look up your address in Leonard Park Pws's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask Leonard Park 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. A zero today does not rule out a jump later - the rules are tightening in 2027.
