Next steps for Broken Arrow, OK
Look up your address in Broken Arrow Municipal Authority's service line inventory. If it says lead, galvanized or unknown, test your tap.

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.
