PAWS downhole liquid/vapor monitoring: In situ vadose zone monitoring and on-line soil vapor extraction offgas monitoring for carbon tetrachloride
- Sandia National Labs., Albuquerque, NM (United States)
This integrated test plan (ITP) describes field demonstration of two Portable Acoustic Wave Sensor (PAWS) systems; all activities of the field demonstration will comply with this plan. This field demonstration covers only the tasks identified herein. The field demonstration for this ITP involves using a down hole probe for in situ monitoring in 4-, 6-, and 8-in. diameter vadose zone wells. An improved system for aboveground monitoring will be tested for real-time, on-line, offgas monitoring as well as for comparison analysis of gas samples pushed to the surface from the in situ probe. The field demonstrations described in this ITP are being conducted as part of the Volatile Organic Compound-Arid Integrated Demonstration (VOC-Arid ID). The VOC-Arid ID is one of several US Department of Energy (DOE) integrated demonstrations designed to support the testing of emerging environmental management and restoration technologies. Initially, the VOC-Arid ID activities will focus primarily on the carbon tetrachloride contamination and associated contamination found in the 200 West Area of the Hanford Site. The 200 West Area carbon tetrachloride expedited response action (ERA) is currently on-going. The ERA is a removal action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The ERA is based on concern that the carbon tetrachloride residing in the soils under the 200 West Area continues to serve as a source of contamination to the groundwater. Thus, the purpose of the ERA is to minimize contaminant migration within the unsaturated soils in the 200 West Area by removing the carbon tetrachloride.
