WAC 173-160-161. How shall each water well be planned and constructed?
Every well must be planned and constructed so that it is:
(1) Adapted to those geologic and groundwater conditions known to exist at the well site to insure utilization of any natural protection available;
(2) Not a conduit for contaminating the groundwater or surface water nor a means of wasting water;
(3) Capable of yielding, where obtainable, the quantity of water necessary to satisfy the requirements the user has stated are needed and for which the well water is intended to be used.
