Your move
Test your own tap with a certified lab first-draw sample; Milo, ME may offer free or low-cost kits through the utility. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Montfort Heights whether it covers that cost before hiring anyone - many utilities now do.
