Next steps for Monticello, NY
Test your own tap with a certified lab first-draw sample; Monticello, NY may offer free or low-cost kits through the utility.

Ask Greentree Water Company whether it covers that cost before hiring anyone - many utilities now do.
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. Why sampled homes are the worst-case ones is in the guide to reading the number. Why an old exceedance still matters: over the limit before, under it now.
