Providing the best possible hydrologic and environmental services to the mining industry involves a detailed understanding of both technical and regulatory issues. Daniel B. Stephens & Associates, Inc. (DBS&A), with its depth of regulatory and technical expertise, offers its clients an integrated approach to solving environmental and closure issues. This approach is anchored by a fundamental understanding of hydrologic and geochemical processes, which provides the basis for innovative and cost-effective solutions.
The strength of DBS&A's services lies in the combination of practical experience coupled with strong academic backgrounds and the knowledge of applicable environmental regulations. Since the early 1980s, DBS&A has worked directly with the mining industry performing state-of-the-art saturated and vadose zone characterization, monitoring, and computer modeling to evaluate infiltration, seepage, leakage, recharge, and contaminant fate and transport.
DBS&A's combined capabilities allow us to address the most complex challenges such as fulfilling closure requirements; optimizing the recovery of metals from leach facilities; evaluation of future water quality in pit lakes; designs of control systems for leaching solution and process water; and protecting the beneficial uses of water. |
