Somsubhra Chakraborty, LSU doctoral student and lead graduate student on the study, stated that "Since the task of identifying a specific petroleum signature is difficult when it is mixed with soil, the present feasibility study indicated that successful combination of chemometry and spectrometry...looks really promising for developing a methodology to identify petroleum contaminated soils in the near future. The fact that this spectroscopic technology does not need prior sample preparation has made it particularly applicable."
Research is ongoing at the Louisiana State University AgCenter to investigate the use of this method for mapping hydrocarbon contaminant plumes and evaluate the unique light signatures of different hydrocarbon compounds (tar, crude oil, diesel, and motor oil). Other research is evaluating predictive models that would be used in conjunction with on-site analysis. Ultimately, this research may lead to the use of airborne or satellite platforms to provide a new means of assessing both known and unknown areas of oil spill contamination.
