Tests on the state list

• 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*').

RIDOH lists "PFAS" for this lab without saying whether it covers drinking water or which PFAS compounds, so PFAS is shown as a certified group. Ask the lab which drinking-water PFAS method (EPA 533 or 537.1) it runs. RIDOH's out-of-state list gives certification categories only ("Contact the Certification Officer for specific analytes/methods"): organic and inorganic chemistry and radiochemistry name no analyte, so no nitrate, arsenic, lead, metals, VOC, uranium or radon certification is shown. Ask the lab.

Homeowner service and turnaround (lab’s own website)

• Takes homeowner samples: yes. The lab’s site says: “Who We serve? ... Homeowners with private wells” source
• Prices: no price printed on the lab’s website when we read it on 15 Nov 2026: ask for a quote.

From the lab’s own website, read 15 Nov 2026 and re-read by a second checker; next check due by 13 Feb 2027. Certification fields come from the state list only.

Around this lab: Cumberland County, ME

• Private wells: about 119,336 people, 41% of Cumberland County’s 289,977 residents (USGS, 2015); rank 1 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 5,972 private-well users (95% range 4,526 to 7,827; 2010 base), rank 8 of 16 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 55% of 153,286 housing units were built before 1980, about the same as 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): 6 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.

Before you send a sample

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Rhode Island certification program.
