Four new Resource Conservation and Recovery Act (RCRA) groundwater monitoring wells were installed at the single-shell tank farm Waste Management Area (WMA) C in fiscal year 2003 to fulfill commitments for well installations proposed in the draft Hanford Federal Facility Agreement and Consent Order milestone M-24-00. Well 299-E27-22, installed upgradient, was drilled through the entire uppermost unconfined aquifer to the basalt and wells 299-E27-4, 299-E27-21 and 299-E27-23 were drilled approximately 40 feet into the uppermost unconfined aquifer and installed 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) and differentiating upgradient groundwater contamination from contaminants released at the WMA. This report supplies the information obtained during drilling, characterization, and installation of the four new groundwater monitoring wells. This document also provides a compilation of hydrogeologic and well construction information obtained during drilling, well development, aquifer testing, and sample collection/analysis activities.

One new Resource Conservation and Recovery Act (RCRA) groundwater assessment well was installed at single-shell tank Waste Management Area (WMA) S-SX in fiscal year (FY) 2005 to fulfill commitments for well installations proposed in Hanford Federal Facility Agreement and Consent Order, Milestone M-24-57 (2004). The need for the new well, well 299-W22-47, was identified during a data quality objectives process for establishing a RCRA/ Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)/Atomic Energy Act (AEA) integrated 200 West and 200 East Area Groundwater Monitoring Network. This document provides a compilation of all available geologic data, spectral gamma ray logs, hydrogeologic data and well information obtained during drilling, well construction, well development, pump installation, aquifer testing, and sample collection/analysis activities. Appendix A contains the Well Summary Sheets, the Well Construction Summary Report, the geologist's Borehole Log, well development and pump installation records, and well survey results. Appendix B contains analytical results from groundwater samples collected during drilling. Appendix C contains complete spectral gamma ray logs and borehole deviation surveys.

This report describes the calendar year (CY) 2003 field activities associated with the installation of two new groundwater monitoring wells in the A-AX Waste Management Area (WMA) and four groundwater monitoring wells in WMA C in the 200 East Area of the Hanford Nuclear Reservation. All six wells were installed by Fluor Hanford Inc. (FH) for CH2M Hill Hanford Group, Inc. (CHG) in support of Draft Hanford Facility Agreement and Consent Order (Tri-Party Agreement) M-24-00 milestones and ''Resource Conservation and Recovery Act of 1976'' (RCRA) groundwater monitoring requirements. Drilling data for the six wells are summarized in Table 1.

This report describes the fiscal year (FY) 2003 field activities associated with the installation of one new groundwater monitoring well and two extraction wells in the 100-KR-4 and 200-ZP-1 Operable Units (OU's). A groundwater monitoring well and an extraction well were drilled in the 100-KR-4 OU and an extraction well was drilled in the 200-ZP-1 OU to support enhancement of the pump-and-treat system. Two boreholes were drilled and completed as wells in the 100-KR-4 OU. One of the boreholes was completed as a groundwater-monitoring well (199-K-l30/C4120) and the other was completed as an extraction well (199-K-l29/C4117). These wells are enhancements to the 100-KR-4 Pump-and-Treat Remediation System, which is designed to intercept contaminated groundwater flowing towards the Columbia River utilizing extraction wells, removing hexavalent chromium through ion exchange, and returning treated groundwater to the aquifer via injection wells located further inland. One borehole was drilled and completed as an extraction well in the 200-ZP-1 OU. Well (299-W15-45/C4119) will be connected to the 200-ZP-1 pump-and-treat system, and is a replacement for existing well 299-W15-33. Dropping water level and low yield at 299-W15-33 prompted the installation of well 299-W15-45 (C4119). Extraction well 299-W15-45 (C4119) will be used to remove carbon tetrachloride, chloroform, and trichloroethylene from the groundwater. Descriptions of drilling, sieve analyses, well completion, well development, pump installation, waste management, civil survey information, and well acceptance walkdown for the two operating units are discussed in Sections 2.0-6.0. Section 7.0 provides a detailed description of subsurface geology observed in the two operable units. Section 8.0 cites references used. Well summary sheets, geologic borehole logs, sieve analysis data, well construction summary reports, well development data, drawdown/recovery curves, and pump installation data are included in Appendices A-E.
