In situ STAR (Self-sustaining treatment for active remediation)

Without industry, Canadians would not enjoy the prosperity they do. But the cost of this progress has been high: as many as 30,000 chemically contaminated sites around the country, each one a potential threat to human and environmental health. Whether because of poor disposal methods or accidental leaks, the soil at these former industrial sites now contains a toxic soup of chemicals, which can enter the air and the groundwater and put humans at risk. Cleaning up these 'brownfield' sites is not only a Canadian health priority, but a key step towards sustainability: many of these abandoned sites are prime real estate and restoring them provides substantial economic and social benefits to urban areas. However, for the most challenging contaminants, virtually no cheap and effective clean-up techniques are available.
