Your move
Look up your address in South Tawakoni Wsc'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. A zero today does not rule out a jump later - the rules are tightening in 2027.
