Abstract

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, andmore »« less

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.},

Description of work for the installation of 3 groundwater wells at the 100-KR-4 and 200-ZP-1 pump and treat remediation system FY2003 Cercla Drilling

Technical Report WALKER, L

This description of work (DOW) documents the requirements for three wells to be drilled and constructed in fiscal year 2003 as part of the 100 KR-4 and 200-ZP-1 groundwater Pump-and-Treat Remediation Facilities on the Hanford Site. Installation of these wells is to replace two existing extraction wells in the 100-KR-4 and 200-ZP-1 Pump-and Treat Systems, and the installation of one new monitoring well at 100-KR-4. Process design upgrades to the 100-K pump and treat system will not be covered in this document. A site plan view map of the 100-KR-4 Pump and Treat Facility is presented in Figure 8-1. Amore »« less

Treatability Test for Removing Technetium-99 from 200-ZP-1 Groundwater, Hanford Site

Conference Byrnes, M; Petersen, S; Tortoso, A; ...

The 200-ZP-1 Groundwater Operable Unit (OU) is one of two groundwater OUs located within the 200 West groundwater aggregate area of the Hanford Site. The primary risk-driving contaminants within the 200-ZP-1 OU include carbon tetrachloride and technetium-99 (Tc-99). A pump-and-treat system for this OU was initially installed in 1995 to control the 0.002 kg /m{sup 3} (2000 {mu}g/L) contour of the carbon tetrachloride plume. Carbon tetrachloride is removed from groundwater with the assistance of an air-stripping tower. Ten extraction wells and three injection wells operate at a combined rate of approximately 0.017m{sup 3}/s (17.03 L/s). In 2005, groundwater from twomore »« less
