2. BASELINE GROUNDWATER DATA <br /> RMCC has gathered data from 13 monitoring wells located around the property. This data <br /> shows the baseline groundwater condition within the alluvial aquifer of the St.Vrain River. <br /> The locations of the sampled and measured wells can be found in Figure 2, below. This <br /> figure also provides information on the groundwater flow and shows the extensive mining <br /> to the south and west of Nix. <br /> Five monitoring wells are on the southern boundary of the mining area, four are located <br /> on the interior of the site within a future slurry-walled area and may be removed when <br /> leak testing is complete, and four are in the northern section of the property. Of the latter, <br /> two are downgradient including the new Mon-9 drilled at DRMS's request in the northwest <br /> corner of the site. Wells Nix-Owens-Mon 1, Nix-Owens-Mon 2, and Nix-Owens-Mon 4A <br /> are now dry (likely due to adjacent dewatering); Well Nix-Varra-Mon 3 is only 1" in <br /> diameter and is not able to be sampled using standard techniques. <br /> 2.1 Baseline Groundwater Quality Data <br /> RMCC's sampling and monitoring program is conducted to thoroughly establish the <br /> baseline water quality and quantity for the site, and to allow for long-term water quality <br /> and water level monitoring. The purpose of the monitoring is to determine if gravel pit <br /> operations have impacted the alluvial aquifer. Table 1 shows a summary of the initial well <br /> sample results from June 2021. <br /> Figure 2: Map of Wells on Nix Site (following page) <br /> 4 <br />
