Performance Testing of Monitoring and Measurement Technologies for Dioxin and Dioxin-like Compounds in Soil and Sediment
Internet-based seminar
Hosted by U.S. EPA
Superfund Innovative Technology Evaluation (SITE) Monitoring and Measurement Technologies Program

A performance verification demonstration of technologies that may be used to determine the presence of dioxin and dioxin-like compounds in soil and sediment samples was conducted under the U.S. Environmental Protection Agency's (EPA's) Superfund Innovative Technology Evaluation (SITE) Monitoring and Measurement Technology (MMT) Program in Saginaw, Michigan, from April 26 to May 5, 2004. Five developers using technologies based on immunoassay or aryl hydrocarbon receptors participated in this demonstration. The primary objectives of the demonstration included evaluating each technology's accuracy, precision, sensitivity, sample throughput, matrix effects, and cost. An assessment of how well each technology's results compared to those generated by high-resolution mass spectrometry (HRMS) using EPA Methods (1613B and 1668A) was also reported. Conclusions and recommendations were obtained by evaluating the results generated by each technology and the reference laboratory from the analysis of 209 soil, sediment, and extract samples. This sample set included performance evaluation (PE) samples (i.e., certified contaminant concentrations or samples spiked with known contaminants) and environmental samples collected from 10 different sampling locations.

A separate innovative technology verification report (ITVR) has been prepared for each developer and is posted on the SITE Homepage (www.epa.gov/ORD/SITE). The performances of the technologies are not compared to one another since it is the policy of the SITE Program not to judge or rank technologies. However, the application of each technology to various environmental monitoring or measurement applications is described in each report.
