摘要

The Tennessee Department of Health and Environment (TDHE) Rules Governing Hazardous Waste Management require that specific ground-water information for interim status units be reported in conjunction with the annual hazardous waste treatment, storage, and disposal report (TN 1200-1-11-.05(6)(e)1 and 2). To be included in the report are, the data from annual/semiannual ground-water sampling, results of statistical analyses, and an evaluation of ground-water surface elevations for units in detection monitoring. Martin Marietta Energy Systems, Inc. manages the K-25 Site in Oak Ridge, Tennessee for the Department of Energy. Two interim status units at K-25 require ground-water monitoring, the K-1407-B and K-1407-C Holding Ponds. Both of these units were surface impoundments that have been drained and the waste sludges removed in response to the November 8, 1988, interim status closure milestone. The K-1407-C Pond was drained in mid-1987 and sludge removal activities were completed in November of 1988. The K-1407-B Pond was drained inOctober 1988, and sludge removal activities were completed in August of 1989. Both units have undergone soil sampling to verify complete sludge removal which would allow them to be ''clean closed'' under interim status regulations. Analytical results of soil samples from K-1407-C Pond are currently being evaluated and soil samples from K-1407-B Pond are undergoing laboratory analysis at this time. This report presents the results of the ground-water monitoring conducted at each unit in compliance with interim status regulations. (ERA citation 18:024752)
