Abstract
Remediation of contaminated soil sites is important to our environment
and the growing population that interacts with these resources.
Contamination of soil due to leaks, spills and seepage is a worldwide
problem usually diagnosed by costly and time-consuming methods primarily
using wet chemistry. Problems in remediation efforts involve finding
technologies that are less time-consuming and more cost effective over
time. Field portable spectrometers that cover key spectral ranges in the
ultraviolet, visible and near infrared regions provide a solution for
fast and easy identification of contaminants in soil. Using a field
portable spectrometer to measure Petroleum Hydrocarbons (TPH) in soil is
a fast and nondestructive method of analysis. Applying UV-VIS-NIR
technology to these samples hydrocarbon spectra can potentially be
characterized by four main absorption features at 1180nm, 1380, 1730nm,
and 2310nm. This presentation aims to highlight the utility of field
portable NIR technology for researchers in addressing potentially
contaminated environments.
