Popis:	Laser-induced fluorescence (LIF) techniques, based on streak camera detection, were used to determine the level of hydrocarbons in the groundwater aquifers of Kuwait. An appropriate classification algorithm, involving discriminant analysis, was used as a rapid in situ screening tool. Forty-two wells distributed throughout the country were sampled and included in the study. These were subjected to analysis by the standard USEPA 418.1 infrared method as well as the LIF method. The infrared analysis focused on the measurement of total petroleum hydrocarbons (TPH). Samples from wells showing high levels of hydrocarbons were also subjected to gas chromatography/mass spectrometry (GCMS) analysis for polycyclic aromatic hydrocarbons (PAHs).
