Abstract
Optical fibers, analytical chemistry, and fluorescence spectroscopy have been integrated to form the new technology of remote fiber fluorimetry. Among the many potential applications of this technology is the measurement of volatile organochlorides in ground water and in the vadose zone. The key to this application was the development of a fiber optic chemical sensor (FOCS) with sub-ppm sensitivity for, at least, chloroform and trichlorethylene (TCE). We present here the concept and instrumentation of remote fiber fluorimetry, the design and laboratory evaluation of an organochloride FOCS, and preliminary field results of the application of the FOCS to contaminated well water.Keywords
