At a glance
No statewide water test and no permit or fee for a household well. All work on a well, including plugging it, must be done by a Kentucky certified water well driller to the 401 KAR 6:310 construction standards (grouted casing, sanitary well cap, 50 ft from a septic tank and 70 ft from a drainfield), and the driller must file the well record with the Division of Water and give you a copy within 60 days. A few local health departments ask for a bacteria sample on a new well; lenders usually do.
No statewide requirement. The Kentucky seller's disclosure form asks whether the water source is a well, spring or cistern and whether there are known problems, nothing more. FHA, VA and USDA loans normally require a bacteria, nitrate and lead sample from a certified lab before closing.
The Division of Water recommends testing a private well, spring or cistern every year for coliform bacteria, and every few years for nitrate, pH, hardness, iron, manganese, lead and copper. Add arsenic in the Jackson Purchase and western coal field, hydrogen sulfide and metals in the eastern coal field, radon in the Bluegrass and Pennyroyal limestone, and test again after flooding, well work or a change in taste, color or smell. Karst wells and springs in the Pennyroyal and Bluegrass should be retested after heavy rain.
No statewide free program. Most county and district health departments will collect a private well or cistern sample and send it to the state Division of Laboratory Services in Frankfort for total coliform and E. coli, for a sampling fee of about $50; call the environmental office of your local health department to schedule. UK Cooperative Extension offices run periodic screening events in some counties.

What comes up with the water depends on the aquifer, and across Kentucky the usual suspects are coliform bacteria (the most common failure statewide, worst in karst limestone wells and springs that draw surface water after rain), nitrate (shallow wells in farm country and the purchase), iron and manganese (coal fields and the jackson purchase). A first full panel tells you which of them apply to your well.
