Groundwater Denitrification Using a Permeable Reactive Barrier
Northern Alberta


Viterra Inc. required an innovative solution to prevent groundwater nitrate concentrations from traveling towards sensitive receptors at a fertilizer facility in northern Alberta. PINTER & Associates Ltd. successfully designed and installed a permeable reactive barrier (PRB) to remove nitrates in situ through biological denitrification. The design is durable, maintenance-free and cost savings of more than 50% were achieved compared to conventional treatments. The system is effectively removing more than 95% of the nitrate from groundwater.
