Next steps for Walcott, ND
Look up your address in Walcott City Of'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 Walcott City Of whether it covers that cost before hiring anyone - many utilities now do. Its latest copper 90th percentile is 1364 ppb (copper action level 1,300 ppb).

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.
