Public / homeowner samples

Public samples: ask the lab

Not stated per lab. MSDH's Private Well Water Testing page says "The Mississippi State Department of Health tests private wells for bacteriological contamination only. Testing for mineral content, chemicals or other contaminants should be done through a private laboratory." and links this list as "Private water testing laboratories participating in MSDH's Drinking Water Lab Certification Program". Call the lab first to ask whether it takes private well samples.

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*').

MSDH lists this lab with EPA lab ID MS00903, certified for: Chemistry, Microbiology. The list names no analytes (for example coliform bacteria, nitrate or lead) and no expiry date; ask the lab which tests it is certified for.

Around this lab: Hancock County, MS

• Private wells: about 17,767 people, 38% of Hancock County’s 46,420 residents (USGS, 2015); rank 6 of 82 counties in Mississippi 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 76 private-well users (95% range 54 to 107; 2010 base), rank 12 of 82 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 27% of 23,715 housing units were built before 1980, below the state share of 41%. 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; 0 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 Mississippi certification program.
