Field Sensor for Measuring TTHM Concentrations in Drinking Water(1001-329)

Triton Systems proposes to develop advanced micro-electro-mechanical system (MEMS) based sensor prototypes for detection of total tri-halomethanes (TTHMs) in the water supply. The sensor is capable of rapid on-site detection of TTHMS in water from low ppb to ppm levels. Measurements were validated with actual water supply samples of interest, in the Phase I program. The sensor is light-weight, capable of rapid selective and reversible detection of THMs, requires no reagents, and is based on COTS components. BENEFIT: The low cost, light weight MEMS sensors being developed by Triton enables instantaneous monitoring of water quality for contaminants such as THMs. In addition to monitoring water quality, and helping ensure compliance of the water supply with EPA regulations, the same sensor platform can be used for quality control of industrial chemicals, fuels and other liquid components. The platform can also be expanded to gas phase sensors for detection of chemical, biological and explosive threats.
