AmerAlia, Inc. Groundwater August 2000 Surface and Groundwater Monitoring Report AmerAlia, Inc., commenced sampling activities to establish water quality information for its experimental pilot plant nahcolite project pursuant to the approved surface and groundwater monitoring plan dated November 23, 1999. This activity included drilling and completion of six groundwater monitoring wells between December 18, 1999 and January 31, 2000. One well, MWD-1, is located in the pillaz among the production wells on Pad 1 and was drilled to just above the Dissolution Surface. Pad 2 is immediately downgradient of the production wells. Wells drilled and completed on Pad 2 aze identified as follows: MWU-2 in the Uinta Formation; MWA-2 at the A-Groove; MWB-2 at the B-Groove; and MWD-2 just above the Dissolution Surface. Baseline water data aze collected from monitoring wells MWU-2, MWA-2, and MWB- 2located on Pad 2. Alluvial groundwater is sampled in wells AM-1 and AM-2 located in the Yellow Creek drainage. Water monitoring locations are presented in Figure 1. Wells MWA-2 and AM-2 were sampled by air-lifting significant quantities of groundwater out of the well bore using compressed air and Z-inch-diameter PVC piping for well MWA-2 while stainless-steel tubing with a e-inch diameter was used in well AM-2. Wells MWU-2 and MWB-2 were purged with bottled nitrogen and samples were obtained using the nitrogen lift system. Field pazameters tested at the time of sample recovery include the following: depth to water level, temperature, conductivity, pH, and total dissolved solids. The date and time of the sampling were noted, along with field site conditions and any other unique features of the sampling events. Daub & Associates, Inc., an independent third-party contractor, conducted the sampling activities for AmerAlia, Inc. August field measurements for these groundwater monitoring wells are presented in Table 1. The analytical laboratory results are presented in Tables 2 through 6. The complete analytical laboratory data reports, which include the Short List constituents for each well as specified in the approved surface and groundwater monitoring plan dated November 23, 1999, are presented in Appendix A. Surface Water Streams Three surface-water stream locations were sampled by Daub & Associates, Inc., to establish water quality information -two upgradient and one downgradient of the project site. The upgradient stream locations include the Corral Gulch drainage near the inactive U.S. Geological Survey (USGS) monitoring station number 09306244 and the Stake Springs Draw drainage above the confluence with Yellow Creek neaz the inactive USGS monitoring station number 09306230. The Corral Gulch location is identified as SW-1; the Stake Springs location is identified as SW-2 (see Figure 1). The downgradient Yellow Creek surface-water stream sampling site is approximately 0.4 mile downstream of the AM-2 alluvial well location. This downgradient location is identified as SW-3. August field measurements for these surface water sites aze presented in Table 7. The analytical laboratory results aze presented in Tables 8 through 10.
