An exemplary embodiment of a method of detecting hydrocarbons in Systems and methods for sensing analytes in an aqueous solution, include pretreating a water sample to provide a test sample. A flow cell includes at least one sensor with a polymer coating having at least partial selectivity for at least one analyte. The flow cell receives a test sample and a reference sample. At least one output signal from the at least one sensor is processed with a microcontroller using a model of the sensor response and a bank of Kalman filters to estimate a concentration of at least one analyte in the aqueous solution.

Shear horizontal-surface acoustic wave system and method for measurement and speciaion speciation of hydrocarbons in groundwater

A process is provided for bioremediating petroleum hydrocarbon contaminated groundwater by applying at least one electron acceptor salt to a ground surface overlying the contaminated groundwater. The process includes identifying characteristics of the aquifer, in which the contaminated groundwater is found, to enable treatment of aquifers at a range of depths below the ground surface.
