Clay-rich bedrock aquitards are commonplace throughout much of the world. However, very little in known about how water and dissolved contaminants are transported through these media. The objective of this research is to improve our understanding of these phenomena. Our research will involve field sampling, laboratory experiments, and computer modeling. Our findings will be of direct value to the potash industry whose mines are located in the aquitard. They will also serve as a benchmark for the use of claystone host rocks as storage sites for radioactive or toxic chemical wastes or as caprocks for containing greenhouse gas storage sites both in Canada and internationally.

富含粘土的基岩弱透水层在世界大部分地区都很常见。然而，人们对水和溶解的污染物如何通过这些介质输送知之甚少。这项研究的目的是提高我们对这些现象的理解。我们的研究将涉及现场采样、实验室实验和计算机建模。我们的研究结果将对位于弱透水层的钾肥行业具有直接价值。它们还将作为使用粘土岩主岩作为放射性或有毒化学废物储存场所或作为加拿大和国际温室气体储存场所盖层的基准。
