摘要

In January 1990, dense nonaqueous-phase liquids (DNAPLs) were discovered at a depth of approximately 274 ft below ground surface along the southern border of the Y-12 Plant Burial Grounds. Immediately after the discovery, an investigation was conducted to assess the occurrence of DNAPL at the site and to make recommendations for further action. Detailed results of the preliminary DNAPL investigation are presented in Haase and King (1990a), and a work plan for assessment and characterization of the DNAPL is presented in Haase and King (1990b). A major task in the work plan calls for the construction and installation of five multiport wells. This report summarizes fluid pressure monitoring activities for the five multiport wells. The report includes a discussion of data collection and processing, and presents the data in the form of hydraulic head graphs. The report does not include interpretation of (1) flow paths, (2) aquifer characteristics, or (3) spatial synthesis of data. As funding and need arises, these topics will be addressed in future reports. To date, a series of fluid pressure measurements have been collected from each of the five Westbay-instrumented multiport wells that were built to quantify groundwater characteristics in the vicinity of a DNAPL plume. These measurements have been converted to hydraulic head, and the results are presented graphically in this report. It is recommended that future tasks use this data to support technically sound environmental remediation decisions. For example, these data can be used to design a remediation strategy or can be used to evaluate and rate a variety of remediation strategies.
