Look up your address in Martin Water System'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 Martin Water System whether it covers that cost before hiring anyone - many utilities now do.
