FRTR Presents...Heavy Metals-Mining Site Characterization and Treatment Session 1

Risk Assessment for Mercury Releases to the Kuskokwim River from the BLM Red Devil Mine Site, Alaska
Doug Cox, Ph.D., BLM Risk Assessment Specialist and Angela Matz, Ph.D., US Fish and Wildlife Environmental Contaminants Specialist
This presentation describes the Red Devil Mine's risk assessment process, a "multiple lines of evidence" approach developed by the Bureau of Land Management (BLM) to incorporate a number of site-specific risk assessment findings into site decision making. Mercury and other site contaminants from Red Devil Mine and other abandoned mines in the Kuskokwim River watershed have been measured in multiple media, leading to concerns about human and ecological risk. Of specific concern is whether mercury methylation and food chain biomagnification poses a risk to human subsistence consumers of locally caught fish. We discuss a number of data sets used to evaluate these risks, including multi-year telemetry studies to track fish movements in relation to mercury sources throughout the Kuskokwim watershed. Fish tissue concentrations of mercury were also collected from many of the tagged fish and are discussed in the context of site and regional consumption patterns.

FRTR Presents...Heavy Metals-Mining Site Characterization and Treatment Session 2

This webinar will focus on different techniques that can be implemented for site characterization and bioremediation. Aqueous Geochemical Modeling can be used to evaluate the cost effectiveness and feasibility of treatment strategies for metal-laden discharges from coal and metal mines. Best practices for monitoring and modeling Anaerobic biochemical reactors (BCR) will be described as it relates to bioremediation of mining sites.

FRTR Presents...Heavy Metals-Mining Site Characterization and Treatment Session 3

This webinar will focus on different techniques that can be implemented for site characterization and modelling. The two techniques of focus are as follows Best practices for monitoring and modeling in situ biogeochemical processes for uranium treatments and AMD will be described as it relates to bioremediation of mining sites.; The use of unmanned aircrafts for biological surveys at sites.

Pre-CERCLA Screening Webinar

The Office of Superfund Remediation and Technology Innovation (OSRTI) is offering a training webinar on the recent "Pre-CERCLA Screening Guidance" issued by the U.S. Environmental Protection Agency (EPA) in December 2016. This guidance is used by EPA, State, and Tribal Superfund site assessment staff and support contractors when deciding if a new site should be added to the Superfund "active site inventory" for more thorough pre-remedial site evaluation. The training webinar will cover all elements of the guidance, from planning the screening to approving the recommended course of action based on the screening. It includes an in-depth discussion of the Pre-CERCLA Screening Checklist/Decision Form that must be completed for each Pre-CERCLA screening. The webinar provides opportunities for participation by the audience, including a section for questions and answers.

Recommended Audience: EPA, State, and Tribal staff and managers and contractor support staff who are involved with planning, conducting, reviewing, and approving Pre-CERCLA screening activities.

Groundwater Statistics for Environmental Project Managers

Interstate Technology Regulatory Council Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013, http://www.itrcweb.org/gsmc-1/) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to:

ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management.

Geospatial Analysis for Optimization at Environmental Sites

Interstate Technology Regulatory Council Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation. The results of geospatial analyses add additional lines of evidence to decision making in optimization opportunities in environmental sites across all project life cycle stages (release detection, site characterization, remediation, monitoring and closure) in soil, groundwater or sediment remediation projects for different sizes and types of sites.

The purpose of ITRC's Geospatial Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites. With the ITRC GRO-1 web-based guidance document and this associated training class, project managers will be able to:
  • Evaluate available data and site needs to determine if geospatial analyses are appropriate for a given site
  • For a project and specific lifecycle stage, identify optimization questions where geospatial methods can contribution to better decision making
  • For a project and optimization question(s), select appropriate geospatial method(s) and software using the geospatial analysis work flow, tables and flow charts in the guidance document
  • With geospatial analyses results (note: some geospatial analyses may be performed by the project manager, but many geospatial analyses will be performed by technical experts), explain what the results mean and appropriately apply in decision making
  • Use the project managerís tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently in decision making
