Description:

Fuel hydrocarbons and chlorinated hydrocarbons comprise large classes of contamination for soils and groundwater. The widespread nature of this problem requires the development of capabilities for continuous, unattended monitoring of contaminant plumes and nearby endangered groundwater supplies. Fiber optic sensors offer a viable route for low-cost, long-term monitoring of soils and groundwater. Eltron Research, Inc., will develop a fiber optic sensor that uses a solvatochromic probe to reversibly detect the presence and nature of contaminants. The Phase I project will address the development of sensor materials and chemistry, neural network-assisted data interpretation, and design of a sensor system that can identify and quantify contaminants. Fiber optic sensors capable of ppb-level detection of hydrocarbons, including fuels and chlorinated hydrocarbons, will find immediate commercial application in monitoring leakage from storage facilities and detection of immediate contamination and health hazards in work areas where these materials are used or stored.
