Description:
This innovative technology evaluation report (ITER) presents information on the demonstration of the U.S. Environmental Protection Agency (EPA) Region 7 Superfund Field Analytical Screening Program (FASP) method for determining polychlorinated biphenyl (PCB) contamination in soil. his method was demonstrated in Kansas City, Kansas, in August 1992. he FASP PCB Method was developed by the EPA Superfund Branch for use at Superfund sites. he method uses a gas chromatograph (GC) equipped with a megabore capillary column and an electron capture detector (ECD). as chromatography is an EPA-approved method for determining PCB concentrations in soil, water, and waste samples. he FASP PCB Method is an abbreviated, modified version of approved methods. oil samples require extraction before GC analysis. o remove matrix interferences, a sulfuric acid cleanup step is used during the FASP PCB Method. he FASP PCB Method was found to be field-portable only in a mobile laboratory, must be done in a temperature controlled environment, and requires a skilled chemist for operation. he detection limit reported by this method for is 0.4 part per million for soil samples. RC used linear regression and inferential statistics to compare the method's data to that from the confirmatory laboratory. hen the data sets were evaluated, the FASP PCB Method's results were statistically the same as the confirmatory laboratory. his method can produce Level 3 data. his method can also identify individual PCB isomers.
