The FACT uses a strip of activated carbon felt attached to the inside surface of the NAPL FLUTe cover. A diffusion barrier isolates the felt strip from the liner. The liner presses the carbon felt strip against the hole wall which allows the activated carbon to absorb contaminants from the pore fluid of the hole water material. The result is a replica of the contaminant distribution dissolved in the pore liquid and the fractures as it is absorbed in the carbon felt. The carbon strip is withdrawn with the NAPL cover and is sectioned and analysed with a mass spectrometer for contaminant concentration in the carbon.
