The following is a summarization of the Kentucky water supply well construction practices and standards.  For additional information please contact the Kentucky Division of Water or your local Kentucky certified water well driller.

Driven point wells and jetted wells can only be used for temporary dewatering purposes; they are no longer approved for drinking water supply use.

When a driven well is abandoned (no longer used) it must be plugged by a Kentucky certified well driller.  The well driller will remove the well casing and screens, and sealing materials will be applied simultaneously from the bottom of the well to a maximum of five (5) feet below finished ground surface. The well driller will then use sealing materials, clay, or other inert material suitable to the proposed land use to fill the upper five (5) feet.

When a hand dug well is abandoned (no longer used) it must be plugged by a Kentucky certified well driller. The well driller will fill the well with sealing materials, dense grade aggregate, limestone sand, or native clay from the bottom of the well to a maximum of five (5) feet below finished ground surface. The top five (five) feet of well casing, tiles, or other well-wall material will be removed and the borehole will be filled with clay or an impermeable material appropriate to the intended use of the land.
