Coal Mine Reclamation
Coal has been the fastest growing energy source in recent years than other sources, such as oil, gas, nuclear, hydro and renewables. There is an increasing amount of coal mines that have been closed in current years, increasing needs for coal mine reclamation. This field and greenhouse research aims to assess the potential of using mineral source derived material as amendments to address soil deterioration issue in coal mine sites and to return the disturbed land to a productive, sustainable and beneficial state.

Engineered Carbon Based Materials For Oil Sands Process Water Reclamation
Oil sands mining generates a large amount of process water. Without proper management process water can pose a threat to the environment and human health as it contains contaminants. By treating process water before discharge to the environment, impacts can be ameliorated. This research aims to develop, characterize, test and optimize carbon based materials such as biochar and hydrochar to treat and reclaim oil sands process water and waste waters from other anthropogenic activities.

Oil Sands Process Water Treatment Using Constructed Wetlands And Biofiltration Systems
Efforts to reclaim oil sands process water and reduce its toxicity have been undertaken. However, the exceptionally persistent nature of its constituents, particularly naphthenic acids, makes remediation challenging. This research focuses on the molecular microbial ecology of these systems to understand underlying mechanisms of pollutant degradation and/or transformation. The aim is to elucidate rates of genomic evolution and organismal adaptation which may help develop an improved bioremediation system through augmentation.

Soil Invertebrates In Land Reclamation
Current reclamation criteria mainly comprise soil physical and chemical properties and vegetation cover, despite an interest in sustainable ecosystems with high biodiversity and resilience. The composition of the soil invertebrate community is directly linked to soil quality, ecosystem health, biodiversity and function, influencing ecosystem recovery. This research aims to advance knowledge of reclamation success indicators by focusing on soil invertebrates.

Cadmium Stability In Spent Biochar For Land Reclamation
Biochar is an adsorptive material that can be used to remove contaminants such as heavy metals from waste waters. After waste water treatment spent biochar must be safety disposed of or reused, potentially in land reclamation. Stability of adsorbed contaminants in the biochar must be determined before use in the environment. This research aims to evaluate the desorption and stability of cadmium in different types of spent biochars through laboratory and greenhouse studies.
