This project was a remediation of a leaking underground storage tank (LUST) at a gas station in Ribera, New Mexico. Application Chemist Lee Tu and Co-Founder and Senior Scientist Patrick Lewis were on-site for training and analyzing comparative analyses for the FROG.
Environmental engineers used a FROG portable gas chromatograph to determine benzene levels in soil that was also contaminated with hydrocarbons, such as Xylenes, that did not require removal from the site. A handheld PID routinely gave false positive readings due to the Xylene contamination. Soil that was benzene contaminated was identified and hauled to a land farming site.
The use of the FROG portable GC significantly reduced the volume of soil that would have been removed using only the PID, resulting in considerable savings of both money and time.
