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). The list prints the Maryville address of Microbac's Knoxville Division for this Nashville lab.

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.
