Publication Year: 



Owners of new water wells should know that one of the most important components of their household water well system can be kept filed away—the well log. A well log is a document containing vital information on the history of the well and the ground surrounding it. Contractors must file well logs with their respective states upon completion of all new wells. However, well owners should have a copy, too, in case a need for maintenance arises over the lifetime of the well. Quick access to and understanding of the well log can be crucial at such times. Well logs differ from state to state. In fact, some are called water well records or drilling reports. Most, however, contain the same basic information. This factsheet provides an explanation of the details contained in well logs.
