Borehole Data Package for RCRA Wells 299-E25-93 and 299-E24-22 at Single-Shell Tank Waste Management Area A-AX, Hanford Site, Washington

Abstract

Two new Resource Conservation and Recovery Act (RCRA) groundwater monitoring wells were installed at single-shell tank Waste Management Area (WMA) A-AX in fiscal year 2003 to fulfill commitments for well installations proposed in the draft Hanford Federal Facility Agreement and Consent Order M-24-00. Well 299-E24-22 has been installed upgradient and well 299-E25-93 downgradient of the WMA. Specific objectives for these wells include monitoring the impact, if any, that potential releases from inside the WMA may have on current groundwater conditions (i.e., improved network coverage); differentiating upgradient groundwater contamination from contaminants released at the WMA; and improving the determination of groundwater flow direction (i.e., improved water table determinations). This report supplies the information obtained during drilling, characterization, and installation of the two new groundwater monitoring wells, 299-E25-93 and 299-E24-22. This document also provides a compilation of hydrogeologic and well construction information obtained during drilling, well construction, well development, pump installation, aquifer testing, and sample collection/analysis activities.
