Cost and Performance Report for the Tri-Service Site Characterization and Analysis Penetrometer System (SCAPS) Hydrosparge Volatile Organic Compound Sensor
Abstract
Site characterization for subsurface contaminants is time consuming and costly. The Hydrosparge VOC sensor was developed for the Tri-Services Site characterization and Analysis Penetrometer System (SCAPS) program to provide in situ VOC detection in ground waters. The system consists of a direct push well for groundwater access, an in situ sparge module, and a direct-sampling ion trap mass spectrometer. During ESTCP-funded demonstration, the Hydrosparge VOC sensor was tested at three geographically different sites across the country. The results obtained with the SCAPS in situ technique indicated a strong linear methods with regression coefficients ranging between 0.63 and 0.88 and the slope of the regression line between 1.1 and 1.2. During the cost and performance demonstration for this report, Hydrosparge VOC sensor directed placement of a reduced number of conventional monitoring wells with a substantial reduction in time and cost.
