Conventional methods for monitoring organic compounds in contaminated sites rely on sample collection, transportation, storage, preparation and instrument analysis by gas chromatography (GC) or high performance liquid chromatography (HPLC). Although the conventional laboratory analysis provides high accuracy, sensitivity and selectivity, it is expensive, time-consuming and discontinuous. To address this issue, cavity enhanced fibre optic sensors will be developed for detection of organic contaminants. The proposed sensors are capable of real-time and on-site measurements. The short-term objective of the proposed research is to design, construct and characterize prototypes in the laboratory. The long-term objective will focus on miniaturization of the instrumentation, followed by on-site field measurements and remote site deployment.
