Task 1.11 - Spectroscopic field screening of hazardous waste and toxic spills. Semi-annual report, January 1--June 30, 1995

PDF Version Also Available for Download.

Description

Techniques for the field characterization of soil contamination due to spillage of hazardous waste or toxic chemicals are time-consuming and expensive. Thus, more economical, less time-intensive methods are needed to facilitate rapid field screening of contaminated sites. In situ detection of toxic chemicals in soil offers both time and cost advantages for field screening with additional application to real-time site monitoring. Fourier-transform infrared (FT-IR) spectroscopy coupled with evanescent mode fiber-optic sensors has been demonstrated as a means to remotely detect and classify petroleum products in water using mid-infrared (MIR) optical fibers. This work demonstrated that a fiber-optic evanescent field absorbance ... continued below

Description

Techniques for the field characterization of soil contamination due to spillage of hazardous waste or toxic chemicals are time-consuming and expensive. Thus, more economical, less time-intensive methods are needed to facilitate rapid field screening of contaminated sites. In situ detection of toxic chemicals in soil offers both time and cost advantages for field screening with additional application to real-time site monitoring. Fourier-transform infrared (FT-IR) spectroscopy coupled with evanescent mode fiber-optic sensors has been demonstrated as a means to remotely detect and classify petroleum products in water using mid-infrared (MIR) optical fibers. This work demonstrated that a fiber-optic evanescent field absorbance sensor (EFAS) could be used to classify petroleum contamination into categories such as crude oil, kerosene, No. 2 fuel and residual distillates using the MIR spectral range. The overall objective of this project is to study the feasibility of using an EFAS FT-IR spectroscopic sensor coupled with cone penetrometry as a field screening method. The Fourier transform infrared cone penetrometry method (FT-IR-CPT) will be developed by building on the work cited above. The specific objectives of this project are: design an accessory for use with FT-IR that interfaces the spectrometer to a cone penetrometer; characterize the response of the FT-IR accessory to selected hydrocarbons in a laboratory-simulated field environment; and determine the ability of the FT-IR-CPT instrument to measure hydrocarbon contamination in soil by direct comparison with a reference method to quantify hydrocarbons from the same soil.
