Tests on the state list

This list does not break certification down by analyte. Ask the lab which tests it is certified for; the groups as written on the list are below.

• Named on the official list The state list names this analyte (or a column for it) for this lab.
• Group-level certification Certified for a parent group (e.g. 'Inorganics') that includes this analyte. Confirm the specific test with the lab.
• Partial group certification The list marks the group as 'Partial'. Confirm this analyte with the lab.
• Subcontracted The lab sends this analyte to another accredited lab (MDH 'X*').

Maine accredits by test; confirm the specific test with the lab.

Around this lab: York County, ME

• Private wells: about 68,406 people, 34% of York County’s 201,169 residents (USGS, 2015); rank 3 of 16 counties in Maine by people on wells.
• At house sale: Statewide (shoreland areas) has a septic system rule (30-A MRSA s.4216). What it requires

• EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 10,409 private-well users (95% range 7,720 to 13,730; 2010 base), rank 3 of 16 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 50% of 115,091 housing units were built before 1980, below the state share of 54%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
• PFAS in public water nearby (public supply, not your well): 10 public systems serving this county reported EPA UCMR 5 results; 1 had a PFOA or PFOS sample at or above 4.0 ng/L.

County figures describe where the lab is, not the lab. Sources: USGS 2015 water use and 2017 arsenic estimates, EPA radon zones, Census ACS table B25034 (2020–2024), EPA UCMR 5 (2023–2026); details and links on the sources page.
