Wells whose owners chose to test at Maine's state lab (HETL): a voluntary sample, not a prediction about any one well. Neighbors can test very differently. No rate is shown when fewer than 20 wells were tested. Source: Maine Tracking Network (Maine CDC), data updated 5/2023

Not in this data: bacteria and radon in water. Maine does not publish those results by town or county. Maine CDC still recommends testing every well for bacteria every year and for radon every 3 to 5 years.

PFAS in Manchester

Maine DEP's PFAS well table does not list any sampling tied to Manchester. That does not mean there is no PFAS in Manchester wells. It only means DEP has not reported testing there.

What Maine recommends for every well

Maine CDC says to test every private well each year for bacteria and nitrate, and every 3 to 5 years for a full panel that includes arsenic, uranium, radon, and lead. Retest after flooding, well or pump work, or any change in taste, smell, or color. The Kennebec County page has the full schedule and the rules for home sales and rentals.

Area-level information cannot determine what is in a specific household's well. Only a properly collected laboratory sample can tell you what's in your water. This page is educational; see the disclaimer.

Parts of central Maine are within Maine DEP's PFAS (sludge-spreading) investigation area. Check the DEP map if your property is near historically licensed spreading sites.
