AAI personnel performed a hydrological assessment as part of geotechnical characterization studies in support of preliminary mining evaluations of tracts C-11 and C-18. Field measurements of water levels, water production, and water quality were performed during core drilling activities at the site and were used to establish test intervals for drill stem (DST) measurements of hydraulic conductivity. AAI directed the activities of drilling and testing tool subcontractors who assisted in the measurements and performed the data analysis
