Public / homeowner samples

Public samples: ask the lab

Not stated per lab. MDE's Be Well Wise page for private well owners says: "Have your water tested periodically by a state-certified laboratory that conducts a drinking water test." It names no lab, and MDE's list does not say which labs take samples from homeowners.

Around this lab: Carroll County, MD

• Private wells: about 72,149 people, 43% of Carroll County’s 167,627 residents (USGS, 2015); rank 6 of 24 counties in Maryland by people on wells.
• At house sale: Statewide (Real Property Article) has a well_test rule (Md. Code, Real Property § 10-713 (Ch. 587 of 2023, HB 11, Private Well Safety Act of 2023)). 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 1,227 private-well users (95% range 848 to 1,855; 2010 base), rank 14 of 24 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 44% of 66,768 housing units were built before 1980, below the state share of 51%. 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): 5 public systems serving this county reported EPA UCMR 5 results; 4 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 Maryland certification program.
