Abstract

This project aims to visualise and quantify chemical gradients at the fringe of a 2-D lab-scale aquifer contaminant plume. We propose to further develop and apply a novel digital imaging technique using fluorescent chemical probes to quantify the spatial concentration distributions, mass fluxes and reaction rate of soluble electron acceptors, organic pollutants and microbial respiration activity in an optically transparent porous medium of quartz sand. These hydrochemical measures of biodegradation will be related to the microbial community that develops under prevailing chemical conditions, and will be used to test mathematical models of natural attenuation performance as a bioremediation technology.
