One-third of the world's demand for potash is being supplied by Saskatchewan and the potash mining industry is a core element driving the rapid economic development in Saskatchewan and Canada. At the same time, however, potash mining operations are generating a substantial volume of mine wastes. Strategies for the responsible management and remediation of potash mining-impacted environments have been in high demand in the industry, especially considering intensified mining activity, elevated water consumption rates, and potential environmental risks posed to groundwater, agricultural soils, and ecological receptors.

萨斯喀彻温省提供了全球对钾肥的三分之一，钾矿开采行业是推动萨斯喀彻温省和加拿大快速经济发展的核心因素。然而，同时，钾盐采矿业务正在产生大量的矿井废物。负责管理和修复受钾盐采矿影响环境的策略在行业需求很高，尤其是考虑到增加的采矿活动，较高的水消耗率以及对地下水，农业土壤和生态受体带来的潜在环境风险。
