Borehole Data Package for Calendar Year 2001 RCRA Wells at Single-Shell Tank Waste Management Area U

摘要

This document is a compilation of the information on well drilling and construction, well development, pump installation, and sediment sampling at three new RCRA wells (299-W-18-40, 299-W19-44, and 299-W19-45) constructed at Waste Management Area U in September 2001. These wells were constructed to the specifications and requirements described in Washington Administrative Codes 173-160 and 173-303. Grab samples for geological description and archive were collected every 5 ft throughout the wells. Borehole and drill cuttings were monitored regularly for organic vapors and radionuclide contaminants.
