Waste materials from oil sands extraction, stored in tailings ponds, can pose a risk to the natural habitat and neighboring communities when they leach into groundwater and surface ecosystems. Until now, the challenge for the oil sands industry is that the proper analysis of toxic waste materials has been difficult to achieve without complex and lengthy testing. And there’s a backlog. For example, in Alberta alone, there are an estimated 1.4 billion cubic meters of fluid tailings.
