Description:
In July 1997, the U.S. Environmental Protection Agency (EPA) conducted a demonstration of polychlorinated biphenyl (PCB) field analytical techniques. The purpose of this demonstration was to evaluate field analytical technologies capable of detecting and quantifying PCB's in soils and solvent extracts. The fundamental objective of this demonstration were(1) to obtain technology performance information using environmental and quality control samples, (2) to determine how comparable the developer field analytical results were with conventional reference laboratory results, and (3) to report on the logistical operation of the technology. The demonstration design was subjected to extensive review and comment by EPA's National Exposure Research Laboratory (ORNL); EPA Regional Offices; the U.S. Department of Energy (DOE); and the technology developers.
The demonstration study was conducted at ORNL under two sets of environmental conditions. The reference laboratory method used to evaluate the comparability of data was EPA SW-846 Method 8081. In September 1998, EnvirLogix's PCB in Soil Tube Assay was evaluated. The ETVR presents information regarding the performance of EnviroLogix's PCB in Soil Tube Assay. Separate ETVRs have been published for the other technologies demonstrated. The demonstration found that the PCB in Soil Tube Assay was simple to operate in the field, requiring about an hour for initial setup and preparation for sample analysis. The test kit had no false positive results (i.e., a result in which the technology detects PCBs in the sample above the detection limit when there actually are no PCBs present), and 4% of the soil sample results were false negatives (i.e., the technology indicates that there are no PCBs present in the sample, when there actually are). For extract samples, the test kit had no false positive or false negative results.
