Volatile Organic Contaminant Sensor
 Microsensor technologies have been developed that can detect an
important class of contaminants know as volatile organic compounds (VOCs).
VOCs include common subsurface and groundwater contaminants such as
chlorinated solvents (e.g., Trichloroethylene) and gasoline components
(e.g., Benzene). One such emerging technology uses a micro-chemical
sensor (chemiresistor) packaged in a waterproof housing that may be able
to provide real-time in-situ monitoring and characterization of VOCs.
The intent is to reduce or alleviate the need for manual sampling and
off-site analysis, which would provide cheaper and more reliable
information.
