On-line SFE/GC for Improved Detection of Trace Organic Pollutants in Ground Water Monitoring

Human and ecosystem health effects are being attributed to increasingly lower levels of toxic contaminants like pesticides and their metabolites. To better understand and manage the fate and transport of toxic compounds, scientists need to measure contaminants with greater accuracy and at still lower levels. This project seeks to improve the detection of trace organic contaminants in ground water by developing a new approach to concentrating sample analytes while minimizing interferences.
