Summary of analytical results for hydrologic studies of wells open through large intervals of the Snake River plain aquifer at the Idaho National Engineering Laboratory, project 1

This report summarizes results of groundwater analyses for samples collected from wells USGS-44, -45, -46 and -59 in conjunction with the INEL Oversight Program straddle-packer project between 1992 and 1995. The purpose of this project was to develop and deploy a high-quality straddle-packer system for characterization of the three-dimensional geometry of solute plumes and aquifer hydrology near the Idaho Chemical Processing Plant (ICPP). Principle objectives included (1) characterizing vertical variations in aquifer chemistry; (2) documenting deviations in aquifer chemistry from that monitored by the existing network, and (3) making recommendations for improving monitoring efforts
