What to do in your house
Test your own tap with a certified lab first-draw sample; Richmond, 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 Bingham Water District whether it covers that cost before hiring anyone - many utilities now do. Its latest copper 90th percentile is 1730 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. The lead result guide covers how utilities pick the homes they sample. Size matters more than most people expect: small vs large water systems.
