Cooperative LLNL/HAZWRAP project to demonstrate determination of field-based retardation factors
Current limitations of field and laboratory technologies make it difficult to determine a distribution coefficient which is necessary to calculate a field-based retardation factor. At Lawrence Livermore National Laboratory, an ongoing study is refining a method to assess the existing partitioning of trichloroethylene (TCE) and perchloroethylene (PCE) between the solid and liquid phases of the aquifer system. The three main components of this method involve (1) measurement of the total VOCs in saturated alluvial deposits, (2) measurement of sediment properties, and (3) measurement of the VOCs in pore water. The design and implementation of new measurement techniques and protocols are being compared to traditional measurement protocols. An overview of these new measurement protocols is presented here along with the algorithm that calculates the field-based retardation factors. A sensitivity analysis is presented to demonstrate the required accuracy of the individual measurements needed to meet the desired accuracy of the final retardation factors. 13 refs., 6 figs., 1 tab.
