Selenium Management Strategies, Selenium Treatment Systems, including Demonstrated Selenium Reductions using Various Treatment Systems

Technical Memorandum to Coal Association of Canada:

“Recent environmental concerns related to metallurgical coal mine developments in Canada have focussed on water quality, with an emphasis on the potential for elevated selenium concentrations downstream of mining operations. These concerns are based mainly on challenges of legacy mining operations in particular, in the Elk River Valley region of British Columbia. Based on recent reporting on the topic of coal developments in the media, there are common misunderstandings regarding the progress being made in the managing, mitigating and treating selenium at coal mining operations.

This memorandum is an independent, third-party summary updating current selenium management practices in North America. It specifically describes various management measures, addresses the challenges of the efficacy, efficiency, and sustainability of various treatment approaches/systems, with a focus on demonstrated removal efficiencies of treatment systems currently being implemented and operated at various coal mining operations.”
