ABSTRACT

The US EPA Chicago Regional Laboratory (CRL) developed methods for qualitative and quantitative determination of polyfluorinated compounds at low ppt concentration levels. A quick extraction and clean-up procedure using 5 mL water/effluent/sludge samples or a 2 gram soil/biosolid sample was developed and is being extensively utilized by CRL in complex matrices.

The incorporation of state-of-the-art sensitive mass spectrometers allows for the quantification of these analytes at the ppt level with less sample manipulation. This is key, since many of these analytes adhere to surfaces which include sampling containers. Data will be presented displaying these affects and the need to process the entire sample in the container of collection. Methods for water, sludge, biosolids and soil are tailored to determine these contaminants in these matrices. Many of the methods developed by CRL are incorporated into consensus standards such as the American Society for Testing and Materials (ASTM).
