– Changing Effluent Regulations in Canada, Helping Mine Sites to Reach New Limits

 - 

On June 1st 2018. Environment and Climate change Canada released the final version of the Metal Mining Effluent Regulations. This will be the first extensive update since they were conceived in 2002.The updated regulations have new or more restrictive limits for key contaminants of concern to many mining operations in Canada.
To adequately support mining operations and meet the regulatory requirements governing them, the need to measure metal concentrations in a variety of sample matrices at ultra-trace levels continues to challenge the industry.
New analytical technologies that support higher sensitivity (lower detection limits), increased data reliability, and lower costs, are available. A review of these technologies: ICP-tandem mass spectrometry (ICP-QQQ) and ICP-high resolution mass spectrometry (ICP-HRMS) and their applications will help mine sites to choose what will work best for a specific site or monitoring program.
