Natural Canadian zeolite is an attractive mineral for the restoration of lands disturbed by the extraction of natural resources such as metals, oil and gas. Dr. Wonjae Chang’s Environmental Engineering Lab developed a dualmineral prototype, using Canadian zeolites, for the desalination of potash brine-impacted water. Dr. Chang also demonstrated the significant accumulation of residual potassium […]

Petroleum contamination in Canada is a major environmental concern. However, remediating petroleum hydrocarbon-impacted soil environments in cold climates, including northern sites, is very challenging and often prohibitively expensive, mainly due to low temperatures (short summer) and remoteness. Bioremediation is the use of microbial populations for degrading and detoxify contaminants and has been considered a cost-effective […]
