Data Package for Groundwater Monitoring Well 299-W19-46 at the 200-UP-1 Operable Unit
One new groundwater monitoring well was constructed at the 200-UP-1 Operable Unit in November 2002. This document provides the information on drilling and construction. One new groundwater monitoring well was constructed in the 200-UP-1 Operable Unit in November 2002. The purpose of the well is to monitor the concentration of technetium-99 and uranium in groundwater associated with the pump-and-treat systems in the 200-UP-1 Operable Unit. The well name is 299-W19-46 and the corresponding well number is C3958. Well 299-W19-46 is located off the southwest corner of the 216-U-17 crib and east of Beloit Avenue. It is a replacement well for well 299-W19-38, which has gone dry. The location of the well is shown on Figure 1. Well 299-W19-46 was drilled in response to the recommendations of a data quality objectives process that indicated a need for additional monitoring wells in the area (BHI-01576). The new well was constructed to the specifications and requirements described in Washington Administrative Code (WAC) 173-160 and WAC 173-303, the Data Quality Objectives document (BHI-01576), and the description of work for well drilling and construction (Fruchter 2002). This document compiles information on the drilling and construction, geophysical logging, and sediment and groundwater sampling applicable to the installation of well 299-W19-46. The information on drilling and construction, well development, and pump installation is summarized from CP-14265. Appendix A contains the Well Summary Sheets (as-built diagrams), the Well Construction Summary Reports, and the geologist's logs; Appendix B contains results of physical properties testing; Appendix C contains the analytical results from groundwater samples obtained during drilling; and Appendix D contains borehole geophysical logs. Additional documentation concerning well construction can be found in CP-14265 and is on file with Fluor Hanford, Inc., Richland, WA.
