Water Well Log Filing
Per the Ohio Revised Code 1521.05, a water well record shall be filed with the Ohio Department of Natural Resources for any well that is drilled. A "well" means any excavation, regardless of design or method of construction, created for any of the following purposes:
- Removing groundwater from or recharging water into an aquifer, excluding subsurface drainage systems installed to enhance agricultural crop production or urban or suburban landscape management or to control seepage in dams and levees;
- Determining the quantity, quality, level, or movement of ground water in or the stratigraphy of an aquifer, excluding borings for instrumentation in dams, levees, or highway embankments;
- Removing or exchanging heat from ground water, excluding horizontal trenches that are installed for water source heat pump systems.
