Since 2008, SRK has worked with Teck to develop technology for using saturated rock fills (SRFs) for treatment of selenium and nitrate in waters at Teck’s Elk Valley metallurgical coal operations. In 2017, SRK and other specialists defined design parameters and layouts for a pilot wellfield and technical and regulatory support during a pilot trial. As of December 2019, the SRF has been removing nearly all nitrate and selenium from up to 10,000 m3/d of mine-impacted water. The technology may reduce water treatment costs by millions of dollars. SRK now supports Teck with expansion of the initial system, design and construction of a second, and initial characterisation of a third.
