The Warren aquifer near Huron, South Dakota was injected with treated surface water for the second season during the summer of 1995, with approximately 9 million gallons injected over 91 days. Approximately 18 million gallons were then recovered and water quality examined. Water quality data were collected from monitoring wells and recharge or recovery water on a regular basis. From this data it was determined that alkalinity was increasing in the recharge area likely due to dolomite dissolution, fluoride was determined not to be suitable for use as a tracer, and the recovered water increased in hardness and manganese concentrations. Trihalomethanes (THM) and trihalomethane formation potential (THMFP) in the recharge and recovery water were reduced after aquifer storage. Transmissivities of surrounding wells determined from pump tests showed no change in the hydraulic properties of the aquifer, while the specific capacity of the recharge well decreased after recharge.
