    摘要: A method for providing the recharge of water into underground aquifers while preventing the mobilization of trace metals. The recharge water may be used for storage and subsequent withdrawal, or to regain or increase the long term beneficial use of an aquifer. The recharge water may be also be used to influence the groundwater flow in the aquifer. Water is treated and recharged by the addition of a small amount of a sulfide compound to remove dissolved oxygen and prevent dissolution of negative valence sulfur bearing minerals, such as pyrite, in the subsurface. The recharged water may increase the pressure head in the aquifer, alter the groundwater flow pattern to prevent the encroachment of objectionable quality water, or to segregate water of different quality. The recharge water may be fresh or brackish depending on the specific objectives of the application.
