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. This report documents demonstration activities, presents demonstration data, and verifies the performance of the Innova Type 1312 Multi-gas Monitor. 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 1312 Multi-gas Monitor. A correlation analysis of 1312 and laboratory TCE and PCE groundwater results revealed a relatively high degree of linear correlation for Savannah River data (r > 0.98) and McClellan data (r>0.89). The type 1312 costs between $28,000 and $35,000, depending on options, and can be operated by a field technician with minimal training. Method development and analysis of multi-component samples may require a higher level of operator training and knowledge in use of the instrument. The throughput rate was in the range of one or two samples per hour. Analytical results are available at the conclusion of a sample run. The results of the demonstration show that the 1312 can provide useful, cost-effective data for routine groundwater monitoring in circumstances where the sample composition in known. As with any technology selection, the user must determine what is appropriate for the application by taking into account instrument performance and the project's data quality objectives.
