Field analytical technologies are becoming increasing relied upon in the performance of site investigations and remediation verification activities. Immunoassay screening methods provide a means to perform rapid analyses of soil, groundwater and waste samples in the field. When used in conjunction with a dynamic adaptive sampling/analyses approach immunoassay field screening data provides valuable information for decision making. Soil samples that were collected as part of site characterization and cleanup verification studies at an industrial facility in the northeast were analyzed using immunoassay kits to allow for expedited decisions on investigation and remediation approaches. The 161 samples collected were analyzed in the field using the Millipore EnviroGard{trademark} PCB and EnSys PCB RISc{trademark} immunoassay test methods. Confirmation analyses on all the samples were conducted in a laboratory using EPA Method 8080. Correlation of the field and laboratory results indicate that false negative and false positive rates vary depending on contaminant concentration and sample the matrix properties. Non-parametric statistical methods used to compare the quantified laboratory data to the immunoassay test range results show no significant difference at the 95 percent confidence intervals for some of the data sets although false positive and negative error in excess of 10 percent were observed in some cases. The results of the evaluation suggest that control of error rates can best be achieved by ensuring rigorous control of the field methodologies.
