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*').

TDEC lists certified contaminant groups, not individual analytes; the list notes that a laboratory may not be approved for all parameters within a group, so confirm the specific test with the lab. TDEC's two lists name different microbiological groups for this lab (commercial list: Membrane Filter- Total, Fecal and E.coli. Microbiological list: Enzyme Substrate - Total Coliform and E.coli; Membrane Filter- Total, Fecal and E.coli; Heterotrophic Plate Count).

Around this lab: Hopkins County, KY

• Private wells: about 1,941 people, 4% of Hopkins County’s 46,222 residents (USGS, 2015); rank 74 of 120 counties in Kentucky by people on wells.

• EPA radon zone (indoor air): Zone 2: moderate potential (average indoor radon may be between 2 and 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 private-well users (95% range 4 to 6; 2010 base), rank 72 of 120 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 57% of 21,001 housing units were built before 1980, above the state share of 47%. 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): 8 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 Tennessee certification program.
