What to do in your house
Look up your address in Holly Tree Acres System 1's service line inventory. If it says lead, galvanized or unknown, test your tap. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Holly Tree Acres System 1 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.
