Looks like a utility or municipal lab

Judging by the name only (this is our label, not the state's). Labs like this usually test their own system. The state list does not say whether it takes samples from the public, so ask before you send one.

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 the microbiological method groups this lab is certified for (Total Coliform and E. coli by enzyme substrate and/or membrane filter). Phone as printed; it may be wrong: 423 area code on a Knoxville address (Knoxville has used 865 since 1999).

Around this lab: Knox County, TN

• Private wells: about 3,678 people, 1% of Knox County’s 451,324 residents (USGS, 2015); rank 48 of 95 counties in Tennessee by people on wells.

• 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 16 private-well users (95% range 12 to 23; 2010 base), rank 45 of 95 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 43% of 218,661 housing units were built before 1980, above 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): 10 public systems serving this county reported EPA UCMR 5 results; 1 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.
