Description:
Summary/Accomplishments (Outputs/Outcomes):
Conclusions:
Simple, reliable and cost-effective field testing of chlorinated hydrocarbons in groundwater is feasible with the sensing platform developed by IOS. The platform consists of premeasured aliquots of a catalytic reagent packaged directly in the sampling port. Upon sampling, the reagent reacts with the chlorinated hydrocarbons present in the groundwater sample to produce degradation byproducts, which are then detected by optical measurements with chromogenic indicators immobilized on a microwell readout platform. The microwell reader is available in handheld prototypes such as ESE-Qaigen devices.
