The oil sands industry presently produces 400 million barrels of oil annually; each barrel is accompanied by 1.25 m3 of tailings. Tailings and associated process-affected water are stored and disposed of in constructed out-of-pit tailings ponds. One of the major threats from tailings ponds is the migration of pollutants into the groundwater system. A University of Alberta research program funded by Suncor began in 2006 to quantify the extent of this impact, and assess chemical oxidation as a remediation option. This NSERC Discovery Program provides the opportunity to undertake a higher risk approach by examining the feasibility of bioremediation, the use of indigenous microorganisms to transform contaminants to non-harmful end products, as an alternate remediation option.

油砂工业目前每年生产4亿桶石油;每桶伴随着1.25立方米的尾矿。尾矿和相关的受工艺影响的水在已建造的坑外尾矿池中储存和处置。尾矿池的主要威胁之一是污染物迁移到地下水系统。一个由森科尔资助的阿尔伯塔大学研究计划于2006年开始量化这种影响的程度，并评估化学氧化作为一种补救方案。该NSERC发现计划通过检查生物修复的可行性提供了采取更高风险方法的机会，使用本土微生物将污染物转化为无害的最终产品，作为替代补救方案。
