| Abstract: | Often liability for environmental damage and cleanup of contaminated sites is made difficult, especially with chemically complex environments containing different pollutants, by the inability to differentiate potential sources (or “owners”) of pollutants from each other. As a result, unnecessary costs may be associated with having to assume financial responsibility for alleged contamination of a site. This article reviews the advances in chemical fingerprinting as a tool in identifying and differentiating sources of hydrocarbon pollutants in chemically complex environments. Appropriate hydrocarbon target analytes and required analytical methods for hydrocarbon fingerprinting are discussed, and new interpretative tools are presented that may be applied to contaminated soil, sediment, and groundwater environmental situations. With these analytical and interpretative techniques, an appropriate allocation of chemical contamination and costs at a site can be made. |
