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.

世界上三分之一的钾肥需求是由萨斯喀彻温省提供的，钾肥开采业是推动萨斯喀彻温省和加拿大经济快速发展的核心因素。然而，与此同时，钾矿开采作业正在产生大量的矿山废物。钾矿开采影响环境的负责任管理和修复策略在行业中的需求一直很高，特别是考虑到采矿活动加剧，水消耗率升高以及对地下水，农业土壤和生态受体造成的潜在环境风险。
