AmerAlia, Inc. <br />Groundwater <br />January 2000 <br />Surface and Groundwater Monitoring Report <br />AmerAlia, Inc., commenced sampling activities to establish water quality information for its <br />experimental pilot plant nahcolite project pursuant to the approved surface and groundwater <br />monitoring plan dated November 23, 1999. This activity included drilling and completion of six <br />groundwater monitoring wells between December 18,1999 and January 31, 2000. One well, <br />MWD-1, was drilled on Pad 1, which is located in the pillar among the production wells. <br />MWD-1 monitors the interval just above the Dissolution Surface. Pad 2 is immediately <br />downgradient of the production wells. Wells drilled and completed on Pad 2 are identified as <br />follows: MWU-2 in the Uinta Formation; MWA-2 at the A-Groove; MWB-2 at the B-Groove; <br />and MWD-2 just above the Dissolution Surface. Baseline water data aze collected from <br />monitoring wells MWU-2, MWA-2, MWB-2, and MWD-2 located on Pad 2. Alluvial <br />groundwater is sampled in wells AM-1 and AM-2 located in the Yellow Creek drainage. Water <br />monitoring locations aze presented in Figure 1. <br />With the exception of existing well AM-1, each well was sampled after it was cleaned up and <br />developed by air-lifting significant quantities of groundwater out of the well using the drill rods <br />and compressed air until the water was relatively cleaz and free of visual suspended material. <br />Field pazameters tested at the time of sample recovery include the following: depth to water <br />level, temperature, conductivity, pH, total dissolved solids and the discharge/flow rate. The date <br />and time of the sampling were noted, along with field site conditions and any other unique <br />features of the sampling events. <br />Daub & Associates, Inc., an independent third party contractor, conducted the sampling activities <br />for AmerAlia. Inc. January field measurements for these groundwater monitoring wells aze <br />presented in Table 1. The analytical [aboratory results aze presented in Tables 2 through 8. The <br />complete anal~vcal laboratory data reports, which include the Long List constituents for each <br />wel[ as specified in the approved surface and groundwater monitoring plan dated November 23, <br />1999, are presented in Appendix A. <br />Surface Water <br />Streams <br />Three surface-water stream locations were sampled by Daub & Associates, Inc., to establish <br />water quality information -two upgradient and one downgradient of the project site. The <br />upgradient stream locations include the Corral Gulch drainage near the inactive U.S. Geological <br />Survey (USGS) monitoring station number 09306244 and the Stake Springs Draw drainage <br />above the confluence with Yellow Creek neaz the inactive USGS monitoring station number <br />09306230. The Corral Gulch location is identified as SW-1; the Stake Springs location is <br />identified as SW-2 (see Figure 1). <br />The downgradient Yellow Creek surface-water stream sampling site is approximately 0.4 mile <br />' downstream of the AM-2 alluvial well location. This downgradient location is identified as <br />SW-3. Januar<~ field measurements for these surface water sites aze presented in Table 9. The <br />analytical laboratory results are presented in Tables 10 through 12. The complete analytical <br /> <br />
