Abstract
Chlorinated solvents are widely used in various industries in Taiwan. However, the leakage and spread of chlorinated solvents into the subsurface results in high mobility of contaminants in heterogeneous hydrogeological conditions, and the investigation and remediation of this are both generally more difficult than is the case with heavy metals or petroleum hydrocarbons. High resolution site characterization, HRSC, is a new approach for developing conceptual site models. HRSC strategies and techniques use scale-appropriate measurements and sample densities to define contaminant distributions, and the physical context in which they reside, with greater certainty, thus supporting faster and more effective site cleanup. In this study we combined a membrane interface probe (MIP) and portable time of flight mass spectrum (portable TOFMS) to carry out an investigation of a chlorinated compound contaminated site. This novel tool can be applied to evaluate plume distribution, contaminant speciation and geological formations by electric conductivity (EC), electric capture detector (ECD) and TOFMS at the same time. This method provides a new tool for developing high resolution CSM, which can provide more precise information about the distribution of contaminants in soil and groundwater.
