Title: Borehole Data Package for Nine CY 2006 Polyphosphate Treatability Testing Wells, 300-FF-5 Operable Unit, Hanford Site, Washington

Abstract

Nine new CERCLA groundwater monitoring wells were installed in the 300-FF-5 Operable Unit in calendar year 2006 to fulfill commitments for the EM-20 funded polyphosphate treatability test. Nine new performance monitoring wells were drilled into the uppermost unconfined aquifer, to the Hanford formation - Ringold Formation contact boundary, and completed within the permeable Hanford fm. unit 1 gravel-dominated sequence. The overall objective of the polyphosphate treatability test is to evaluate the efficacy of using polyphosphate injections to treat 300 Area uranium contaminated groundwater in situ. The objective of this work was to install the performance monitoring network surrounding the existing treatability injection well C5000 (399-1-23) in support of the implementation of a field scale demonstration of the polyphosphate technology.

  • This report supplies the information obtained during drilling, characterization, and installation of the new groundwater monitoring well. This document also provides a compilation of hydrogeologic and well construction information obtained during drilling, well development, and sample collection/analysis activities.
  • Four new CERCLA groundwater monitoring wells were installed in the 300-FF-5 Operable Unit in FY 2006 to fulfill commitments for well installations proposed in the Hanford Federal Facility Agreement and Consent Order Milestone M-24-57. Wells were installed to collect data to determine the distribution of process uranium and other contaminants of potential concern in groundwater. These data will also support uranium contaminant transport simulations and the wells will supplement the water quality monitoring network for the 300-FF-5 OU. This report supplies the information obtained during drilling, characterization, and installation of the new groundwater monitoring wells. This document also provides amore » compilation of hydrogeologic, geochemical, and well construction information obtained during drilling, well development, and sample collection/analysis activities.« less
  • The remedial investigation of the 300-FF-5 operable unit was initiated in fiscal year 1991. A major part of the investigation involves the construction of eight new groundwater-monitoring wells in the upper confined aquifer beneath the operable unit. The upper confined aquifer has a head gradient significantly higher (approximately 30 ft) than the unconfined aquifer. Because of this, the US Environmental Protection Agency and the State of Washington Department of Ecology requested, through review comments associated with the operable unit work plan (DOE 1990), the US Department of Energy to prepare a description of borehole seal emplacement and testing for thismore » specific operable unit. They further requested that the resulting documentation be approved by the regulatory agencies prior to constructing the first confined aquifer-monitoring well. The description of seal emplacement and testing in new groundwater-monitoring wells completed in the upper confined aquifer in the 300-FF-5 operable unit is presented in this report. This work applies only to wells drilled for the 300-FF-5 operable unit. The area under consideration is located on the Hanford Reservation. 19 refs., 19 figs., 1 tab.« less
  • Pacific Northwest National Laboratory (PNNL) is presently conducting a re-evaluation of remedies addressing persistent dissolved uranium concentrations in the upper aquifer under the 300 Area of the Hanford Site in southeastern Washington State. This work is being conducted as a Phase III feasibility study for the 300-FF-5 Operable Unit on behalf of the U.S. Department of Energy. As part of the feasibility study process, a comprehensive inventory of candidate remedial technologies was conducted by PNNL. This report documents the identification and screening of candidate technologies. The screening evaluation was conducted in accordance with guidance and processes specified by U.S. Environmentalmore » Protection Agency regulations associated with implementation of the Comprehensive Environmental Response, Compensation, and Liability Act process.« less
