• 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*').

MassDEP lists this certified lab as not offering services to residential customers and gives no analyses for it.

Around this lab: Essex County, MA

• Private wells: about 53,241 people, 7% of Essex County’s 776,043 residents (USGS, 2015); rank 4 of 14 counties in Massachusetts by people on wells.
• At house sale: Statewide (Title 5) has a septic system rule (310 CMR 15.301-15.305 (Title 5)). 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 2,067 private-well users (95% range 1,316 to 3,244; 2010 base), rank 5 of 12 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 69% of 329,776 housing units were built before 1980, about the same as the state share of 67%. 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): 33 public systems serving this county reported EPA UCMR 5 results; 16 had a PFOA or PFOS sample at or above 4.0 ng/L.

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 Massachusetts certification program.
