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. This includes familiar liquids like gasoline and oil, industrial by-products like solvents and coal tars, and even a few substances now banned in Canada, including PCBs. When groundwater flows through these sites it becomes unusable-and potentially dangerous.  But cleanup is not cheap. Using current techniques, it would cost tens of billions of dollars to clean up all contaminated sites in Canada.In this research, Dr. Jason Gerhard is developing a wider array of practical and cost-effective technologies and strategies for eliminating hazardous chemicals in the soil.  Instead of guessing at what works right, Dr. Gerhard recreates the environment of a toxic site in his lab, and then runs a number of tests to see which strategies work best. This helps him understand the complex ways different chemicals, soils, and rocks interact during the restoration process. The results of these experiments are fed into special computer software created by Dr. Gerhard's research group. This software allows the researchers to simulate all manner of contaminated sites, and to try out a wide variety of treatments. That way, when it comes to tackle the problem in the real world, it can be done efficiently and with the most modern and cost-effective techniques.Restoring contaminated industrial sites is critical to the health and sustainability of Canada. This research will reduce the health risks of these sites, and financial liability associated with them.

如果没有工业，加拿大人就不会享受现在的繁荣，但这一进步的代价却很高：全国各地有多达 30,000 个化学污染场地，每个场地都对人类和环境健康构成潜在威胁。无论是因为处置方法不当。由于意外泄漏，这些前工业场地的土壤现在含有有毒的化学物质，其中包括汽油和石油等熟悉的液体、溶剂和煤焦油等工业副产品，甚至还有加拿大现在禁止的一些物质，其中包括。当地下水流过这些地点时，它就会变得无法使用，并且存在潜在危险。但使用目前的技术，清理加拿大所有受污染的地点将花费数百亿美元。在这项研究中，杰森博士说。格哈德正在开发更广泛的实用且具有成本效益的技术和策略，以消除土壤中的有害化学物质。格哈德博士没有猜测什么是正确的，而是在他的实验室中重建了有毒场地的环境，然后运行了一些测试次数看看哪种策略最有效，这有助于他了解不同化学物质、土壤和岩石在恢复过程中相互作用的复杂方式。这些实验的结果被输入到由格哈德博士的研究小组创建的特殊计算机软件中。研究人员模拟各种污染场地，并尝试各种治疗方法，这样，在解决现实世界中的问题时，就可以使用最现代、最具成本效益的技术高效地完成。恢复受污染的工业场地对于健康和可持续发展至关重要这项研究将减少这些场所的健康风险以及与之相关的财务责任。
