Best Well Water Testing in Knoxville, TN

What should I test my well water for in Tennessee?

TDEC recommends annual testing for total coliform bacteria (and E. coli when indicated) and nitrate for private wells at minimum. Depending on local geology, nearby land uses, and plumbing or well age, many Tennessee well owners also periodically test for metals (such as lead and arsenic), pH, iron, manganese, volatile organic compounds, and PFAS where there is a plausible exposure pathway. TDEC publishes lists of laboratories certified for drinking water analyses under its Drinking Water Laboratory Certification Program and supporting guidance for well owners.

How often should well water be tested in Tennessee?

Test annually for bacteria and nitrates. Comprehensive testing every 2-3 years is recommended. Test immediately after any flooding event, if you notice changes in taste, odor, or color, or if you receive a TDEC or local health department notice about contamination in your area. Tennessee has extensive monitoring programs that may alert you to local issues.

Where can I get my well water tested in Tennessee?

Use a laboratory certified by TDEC for the parameters you need (TDEC's Drinking Water Laboratory Certification Program certifies laboratories for EPA-based drinking water methods). Your county environmental health program (local health department), University of Tennessee Extension county office, or TDEC regional field office can help with sampling instructions and choosing a certified lab. Some well service companies also partner with certified laboratories.
