Same Country but Different Planet – A comparison of Risk Assessment Approaches in BC and Ontariokeyboard_arrow_down
Working as a risk assessor in BC and Ontario has taught Michelle Ashley many things. It has also caused her hair to turn grey. Taking a “learn to do by doing” approach, Michelle has learned that the regimes share the same goal: to identify contamination that may pose a risk to human and/or ecological heath and determine how to manage the risk. Both jurisdictions use many of the same tools, but the road maps to get to this goal are however, different. Often when one jurisdiction goes right, the other goes left and the risk practitioner goes greyer and greyer. Whether it is order of operations, report format or review, there are several variances on approach. Michelle will discuss some of the key technical and administrative differences in the maps used by each jurisdiction.
How do repeatedly measure water levels and obtain water samples from monitoring wells completed in an aquifer beneath thick permafrost? How do you stop the water in the well from freezing? And how do you characterize an aquifer that’s been cross-contaminated by a deep open borehole? Join us on Wednesday April 8 at 10 AM Pacific, when John Sankey of True Blue Technologies presents more fascinating case studies where novel applications of multilevel monitoring systems were used to develop an effective conceptual site model.
Stakeholder Roadmap: A Guide to Effective Active Engagement using Social Methodologieskeyboard_arrow_down
Stakeholder engagement is thought to be elusive, complex, and expensive. Currently, remediation industry has acknowledged to be deficient in this area, in 2015 an international SuRF project published how to better integrate the social dimension. This presentation builds on that work. Active stakeholder engagement is beneficial to projects by reducing delays. And, using known, effective engagement strategies allows for better outcomes for consultants, proponents, and the community. As there is no ‘one-size-fits-all’ approach that is appropriate for any project, this roadmap sets out to demystify engagement, and uses guiding principles in a framework allowing users help effectively guide their stakeholder engagement process.
Groundwater impacts at mining sites are often comingled mixtures of sulfate, associated with the sulfuric acid leach solutions commonly used in mineral extraction, as well as various metals associated with the ore body or host rock being mined. The focus of the research presentation is the development of cost effective and reliable processes for biologically reducing sulfate, yielding biological and abiotic chemical processes that result in the precipitation or geological sequestration of the metal-based contaminants present in the groundwater at mining sites. This presentation describes the development and microcosm testing of SiREM’s MB-1® sulfate reduction consortium, grown in water from a metal impacted mine site located in Chile. This research is ongoing and is the basis of new in-situ passive approaches and bioremediation products for remediating metal-based groundwater contamination at mining sites.
Managing Complex Sites with High Resolution Site Characterization and Focused Remediationkeyboard_arrow_down
Recent groundwater characterization and instrumentation approaches have proven helpful in providing a sound and defensible Conceptual Site Model (CSM) to help design a range of different remedies to reach the overall goal at a complex site. High Resolution Site Characterization. An integrated approach has been developed to use ultra-high resolution scanning technology and three-dimensional (3-D) data integration and visualization, to more effectively characterize baseline groundwater hydrogeology, contaminant distribution, and identify microbially active subsurface zones as confirmed by Next Generation Sequencing. Focused Remediation. – At the South Tacoma Channel Superfund site in Tacoma, Washington, targeted remedies were applied within the complex stratified regime.
