Wells penetrating artesian water zones: RCW 90.44.070.

(1) Wells taking water from artesian zones shall contain water-tight casings from the ground surface down through and properly sealed into the confining layer.

(2) Issuance of permits to take water from an artesian zone shall not be stopped when existing wells penetrating said artesian zone no longer flow at ground surface; rather, a reasonable seasonal lowering of the water table will be permissible to more fully utilize the reservoir capacity of the aquifer.

(3) Where the waste of water through improperly constructed wells has been found and wasting of said water is depriving others of water to which they are entitled, or causing an unreasonable drop in the water table, or threatens permanent damage to the aquifer, the department of ecology shall direct the owner to make necessary repairs to correct the situation. (RCW 90.44.120.)
