Paper Abstract

A fiber-optic fluorometer that uses laser excitation has been developed to perform field screening of contaminated soils at hazardous waste sites. The unit uses a nitrogen laser and an optical multichannel analyzer to develop data on contaminate concentrations in soil in place at a site. The unit operates with a soil cone penetrometer and can obtain data down to a maximum depth of approximately 50 meters. Use of this equipment allows rapid mapping of the distribution of leaked or spilled contaminants that contain fluorescing components. The soil fluorometer has been particularly useful in tracking the movement of hydrocarbons, such as diesel fuel or gasoline.
