At a glance

Water test for a new wellNot required statewide

No statewide water test and no state permit for a household well. The Water Well Act requires the well to be drilled by a TDEC-licensed water well driller to the rule 0400-45-09 construction standards (steel casing at least 19 ft deep or into bedrock, grouted, ending 6 in above grade with a sanitary seal; 50 ft from septic tanks and drainfields, 10 ft from property lines), and the driller must file a well report with TDEC within 30 days. A few counties permit wells through the county health department, Shelby County most notably, and lenders usually want a bacteria test on a new well.

Water test when a home is soldNot required statewide

No statewide requirement. The Tennessee Residential Property Condition Disclosure asks only whether the water supply is a well and whether the seller knows of problems. FHA, VA and USDA loans normally require a bacteria, nitrate and lead sample from a certified lab before closing.

What the state recommends

TDEC and the Department of Health recommend testing a private well for coliform bacteria every year, and for nitrate, pH, hardness, iron, manganese, lead and copper at least once and again every few years. Add radon and uranium in East Tennessee bedrock wells, arsenic on the Highland Rim and in West Tennessee sands, pesticides in shallow Coastal Plain wells, and test again after flooding, well work or a change in taste, color or smell. Karst wells in Middle and East Tennessee should be retested after heavy rain, when bacteria and turbidity spike.

Free or low-cost testingAvailable

No statewide free program. The Department of Health laboratory in Nashville (and the Knoxville regional laboratory for East Tennessee) tests private well and spring samples for bacteria, nitrate and metals for a modest fee; bottles and forms come through the county health department or the laboratory (615-262-6337). Some county health departments and UT Extension offices run periodic screening days.

Well depth and water chemistry

Wells in Perry County typically reach 110 to 250 feet; the median of 450 residential and farm wells reported to TDEC since 2000 is 170 feet. What comes up with the water depends on the aquifer, and across Tennessee the usual suspects are coliform bacteria (the most common failure statewide, worst in karst limestone wells that draw surface water after rain), nitrate (farm counties and shallow west tennessee wells), hardness (limestone across middle and east tennessee). A first full panel tells you which of them apply to your well.
