Abstract
The goal of this research project (through Phase III) is to develop a chemical sensor that can be multiplexed into water distribution systems to provide early warning of poisoned water supplies. This will be accomplished by developing surface-enhanced Raman (SER) sensors that can be integrated into water supply systems and coupled to a central Raman analyzer via fiber optics. In Phase I, Real-Time Analyzers, Inc., will develop the sensors to selectively detect several chemical agent hydrolysis products, toxic industrial chemicals, and pesticides at concentrations below 1 mg/L in flowing streams in 10 minutes. In Phase II, Real-Time Analyzers will interface the SER sensors into optical probes that tie into selected water distribution points, improve sensitivity to 10 μg/L in 10 minutes for 30 analytes, and develop multiplexing software compatible with supervisory control and data acquisition systems. Sensitivity, selectivity, and process capabilities will be evaluated using actual chemical warfare agents at Aberdeen Proving Ground under a subcontract.
