Description:
The U.S. Environmental Protection Agency, through the Environmental Technology Verification Program, is working to accelerate the acceptance and use of innovative technologies that improve the way the United States manages its environmental problems. As part of this program, the Consortium for Site Characterization Technology was established as a pilot program to test and verify field monitoring and site characterization technologies. Reports documenting the performance of the other technologies have been published separately. The demonstration was conducted at two geologically and climatologically different sites: the U.S. Department of Energy's Savannah River Site, near Aiken, South Carolina, and McClellan Air Force Base, near Sacramento, California. The demonstration provided adequate analytical and operational data with which to evaluate the performance of the Model 4100. Correlation analysis between Model 4100 and laboratory results produced correlation coefficients (r) in the range of 0.82 to 0.97 at low (less than or equal to 100 ug/L) contaminant concentrations. Correlation coefficients were 0.97 or greater at high (greater than 100 ug/L) concentrations. Model 4100 sample throughput rates were 2 to 3 samples per hour.
Under appropriate applications, the Model 4100 field-portable gas chromatograph can provide useful, cost effective data for environmental site characterization and routine monitoring. As with my technology selection, the user must determine what is appropriate for the application by taking into account the instrument performance and the project's data quality objectives.
