The present paper highlights the utility of petroleum chemical fingerprinting in
investigating known or suspected tank farm releases. A detailed characterization of
groundwater was carried out in three tank farms located in north, central and south Italy.
Eighteen parent polycyclic aromatic hydrocarbons (naphthalene through coronene), nalkanes
(n-C10 through n-C36), isoprenoids pristane and phytane, vanadium, nickel and lead
were determined. Distribution profiles and diagnostic ratios of specific fuel constituents
were studied in order to identify contamination sources. Data analysis shows that in the
study sites multiple pollutant sources affecting the tank farms and the surrounding
industrial areas are present. Both high concentrations of contaminants coming from fuel
releases and noticeable concentrations of biogenic compounds were found. A detailed data
analysis suggests the origin and the level of pollution of the three sites. The results
demonstrate that threshold concentration approach is not always sufficient and it is
necessary to carry out studies of contaminant distribution and their diagnostic ratios in
order to perform a successful forensic investigation.
