Your move
Look up your address in Manokotak Heights W/S'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 Manokotak Heights W/S whether it covers that cost before hiring anyone - many utilities now do. Its latest copper 90th percentile is 1590 ppb (copper action level 1,300 ppb).
These figures describe homes the utility sampled, not your tap. Only your service line record or a test of your own water answers the question for your house.
