Next steps for Ocala, FL
Look up your address in On Top Of The World's service line inventory. If it says lead, galvanized or unknown, test your tap.

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.
