Canada's water supply is under threat due to diminishing quantities of clean, non-toxic water for supporting wildlife and also for domestic livestock such as cattle. In some parts of Canada, high concentrations of sulphur compounds are responsible for creating environments toxic to many species. These include mine affected environments such as mine pit lakes and tailing ponds. In other areas, such as the Okanagan, BC, there is a shortage of drinking water for cattle due to naturally high sulphate concentrations. In addition, some stratified lakes high in sulphide have very low diversities and are uninhabitable by fish. Thus, our work is directed at studying biological and other environmental factors that regulate sulphur cycling in these systems with a view to developing in situ bioremediation strategies for improving water quality.

加拿大的水供应正受到威胁，因为用于支持野生动物和家畜(如牛)的清洁、无毒水的数量正在减少。在加拿大的一些地区，高浓度的硫化物造成了对许多物种有毒的环境。这些环境包括矿坑、湖泊和尾矿库等受地雷影响的环境。在其他地区，如不列颠哥伦比亚省的奥卡纳根，由于天然的高硫酸盐浓度，牛的饮用水短缺。此外，一些硫化物含量高的层状湖泊的多样性很低，不适合鱼类居住。因此，我们的工作旨在研究调节这些系统中硫循环的生物和其他环境因素，以期制定改善水质的就地生物修复策略。
