What are the state requirements for capping or plugging of test wells?
A test well must be plugged promptly after abandonment, following procedures specified by the DEQ. A well is considered abandoned if it is inactive for one year, unless an extension is granted by the DEQ based on showing a good reason to keep the well open. Wells must be plugged in a manner that seals off and confines any fluids in the formations penetrated by the well, and prevents any surface water or other materials from entering the well. Unplugged wells have locking caps installed.
