During site investigation activities at the MPA, an on-site measurement technology (HAPSITE GC/MS) was used to determine the appropriate placement of monitoring wells to characterize the horizontal extent of a trichloroethene (TCE) plume migrating beyond site boundaries. A drill rig drilled borings from which ground water samples were collected using disposable bailers. Through the use of quantitative field analyses, real-time VOC results from the samples were used to model the plume, to guide decisions about locating additional borings, and to select which borings would be converted to permanent monitoring wells. Two years later, real-time VOC results were again successfully used, this time to characterize the vertical extent of TCE contamination. Field-Portable Analytical Inc. provided the HAPSITE GC/MS instrumentation, the associated standards and supplies, and the analytical chemist operator able to produce VOC data of the quality desired by the client.
