3. Groundwater <br /> Groundwater is generally found at the Arkansas River level in the permit area and will be <br /> encountered in the gold mining operation throughout the site. It is expected that excavation in <br /> each new mining area will encounter groundwater that will be pumped and dewatered into each <br /> new cuts adjacent topographic low and resultant sediment settling pond. This way, no <br /> groundwater is removed from the site as all groundwater will seep back into the alluvium via the <br /> sediment settling pond after being repeatedly recycled in the respective sluice plant. <br /> According to searches on the Division of Water Resources (DWR) database,there are six wells <br /> within 600 feet of the mining pit of the Box Creek Placer Mine site permit boundary. The <br /> following table details these wells. <br /> DWR Well ID Owner Use <br /> 50804-F Joseph Louth Domestic <br /> 162377 City of Aurora Domestic <br /> 51724-MH City of Aurora IMonitoring/Sampling <br /> 293367 City of Aurora Monitoring/Sampling <br /> 293361 City of Aurora Monitoring/Sampling <br /> 293360 City of Aurora Monitoring/Sampling <br /> 4. Water Consumption for the Operation and Water Rights <br /> The gold operation will use water for dust suppression on roads and in processing plants, with <br /> minor domestic uses in the shop building. All water on-site will be recycled; placer gold <br /> operations are net water consumers due to evaporation. This contributes to the fact that there is <br /> no discharge from the site. The Operator will allow all wash water to enter settling sediment <br /> ponds. From these ponds, a pump will recycle clean water back to the sluice plant. Makeup and <br /> original water will be obtained from leases with either the City of Aurora or the City of Pueblo. <br /> Box Creek Placer Mine Greg l.a wks and Associates Pl.t <br /> September 2018 G-3 <br />
