Well Logs

A well log is a form completed by a well driller when a well is drilled, and submitted to the Washington State Department of Ecology.  Some of the information found on a well log includes:

    • when the well was drilled and who drilled it
    • the depth of the well and how far down water was found
    • the diameter of the well and what it is lined with
    • what types of soil or rock the well goes down through
    • how much water flows from the well

It is good for well-owners to have a copy of their well log.  It is frequently required for building permits, and other situations which may require proof of drinkable water.
