Proof of concept to treat nitrate impacted groundwater

Our client is considering biological treatment of elevated nitrate concentrations in the seepage generated from their mine tailings facility. iWater collected impacted water from the site and completed microcosm studies at our laboratories to identify the optimum food source for the indigenous consortiums to support denitrification metabolism for nitrate reduction. This was followed up with microbial diversity studies in which iWater established that the indigenous bacterial community does have the capability to reduce nitrate but not at a feasible rate and hence bioaugmentation was needed. The laboratory column demonstration showed that the elevated nitrate concentrations could be reduced from concentration of 126 mg/l Nitrate as N to <0.35 mg/l Nitrate as N by optimizing the donor and augmenting the indigenous bacteria.
