This study presents a non-invasive imaging method for in situ concentration determination of conservativetracers and pollutants in a two-dimensional glass pore network model. The method presented isan extension to the work by Huang et al. [1], and Thomas and Chysikopoulos [2]. The method consists offabricating the glass pore network model using a photolithography technique, conducting flowthroughcontaminant transport experiments, taking digital photographs at various times of the two-dimensionalpore network under ultraviolet or visible light source, and determining the spatially-distributed pollutantconcentrations by measuring the color intensity in the photographs with comparative imageanalysis. Therefore, the method is limited to fluorescent or colored pollutants and tracers. The methodwas successfully employed to in situ concentration determination of uranine and red color tracers.
