Confining of water to their original strata

During the drilling of any testhole, all freshwaters and waters of present or probable value for domestic, commercial, or stock purposes encountered shall be confined to their respective strata and shall be adequately protected by methods approved by the state geologist. Special precautions shall be taken in drilling and abandoning of testholes to guard against any loss of artesian water from the strata in which it occurs, and to prevent contamination of artesian water by objectionable water.
