The objective of this study was to investigate the means of establishing nonpolluted ground water and root zone systems in areas where surface mining intercepts physiochemically unsuitable overburden materials. Overburden may need to be sampled on a 60-m grid to delineate materials unsuitable for reclamation and to accurately implement selective handling operations. After 3 years the buried material remains above the reestablished aquifer and below the root zone. At least a portion of the postmine aquifer had hydraulic conductivity rates lower than the premine system, indicating the reestablished aquifer may, in part, conduct ground water very slowly. Postmine ground water chemical quality in spoil materials had poorer quality compared with premine ground water.
