This project began when a long term fertilizer plume from an operating distribution facility threatened to compromise a nearby potable groundwater well. The client desired to continue to operate the facility while ensuring the offsite well could be protected. Ryan designed and oversaw installation of a large scale permeable reactive barrier(PRB) to treat groundwater leaving the site through anaerobic bioremediation. The project successfully demonstrated that PRBs can be a cost-effective long-term risk management solution for shallow groundwater nitrate and/or sulphate plumes, in lieu of conventional “dig and dump” or lagoon type remedial applications. Cost savings versus conventional approaches here were in excess of 90%.
