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*').

ADEM certifies labs per list (bacteriological, chemical, PFAS) and names no individual tests or analytes; ask the lab which tests it is certified for and whether it takes samples from homeowners.

Homeowner service and turnaround (lab’s own website)

• Takes homeowner samples: yes. The lab’s site says: “analyzes drinking water samples for specific bacteria from public water systems regulated by the ADEM and from private sources such as building contractors, home wells” source
• Who collects: You collect the sample with the lab's bottles. source

Around this lab: Mobile County, AL

• Private wells: about 38,321 people, 9% of Mobile County’s 415,395 residents (USGS, 2015); rank 1 of 67 counties in Alabama by people on wells.

• EPA radon zone (indoor air): Zone 3: low potential (average indoor radon may be less than 2 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 144 private-well users (95% range 99 to 212; 2010 base), rank 3 of 67 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 51% of 186,082 housing units were built before 1980, above the state share of 42%. 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): 13 public systems serving this county reported EPA UCMR 5 results; 2 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 Alabama certification program.
