ITRC Mining Waste Treatment Technology Selection - March 24, 2016,1:00PM-3:15PM
EDT (17:00-19:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mining
Waste Technology Selection site to assist project managers in selecting an applicable
technology, or suite of technologies, which can be used to remediate mine waste contaminated
sites. Decision trees, through a series of questions, guide users to a set of treatment
technologies that may be applicable to that particular site situation. Each technology is
described, along with a summary of the applicability, advantages, limitations, performance,
stakeholder and regulatory considerations, and lessons learned. Each technology overview links
to case studies where the technology has been implemented. In this associated Internet-based
training, instructors provide background information then take participants through the decision
tree using example sites. Project managers, regulators, site owners, and community
stakeholders should attend this training class to learn how to use the ITRC Web-based Mining
Waste Technology Selection site to identify appropriate technologies, address all impacted
media, access case studies, and understand potential regulatory constraints. For more
information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive.

Identifying the Potential for Methylation of Mercury at Mining Sites - March 29, 2016,
1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar presents two case studies that highlight
the impacts of treatments and management strategies on mercury methylation and
methylmercury release at mining sites. Methyl mercury (MeHg) is a toxic and bioavailable form
of mercury. The first case study will document results of a mining-influenced waters treatability
study conducted at the Formosa Mine Superfund site. One component of this investigation
assessed the influence of sulfate-reducing bacteria on the production and release of MeHg
during the treatment of mining-influenced water. The results are being used to inform the
design, application, and assessment of sulfate-reducing biochemical reactors. The second looks
at the impact of water level fluctuation on sediment in the Cottage Grove Reservoir, located
downstream from the former Black Butte mercury mine of the Black Butte Superfund site.

Results suggest that exposure of sediments to air while water levels are lowered may replenish
the supply of sulfate (and/or other electron acceptors) needed to stimulate microbial production
of MeHg mercury when the reservoir level is raised. For more information and to register, see

facilitate better decision making for accelerated cleanups. The instructional methodology for this
course includes lectures and demonstrations of using EPA risk and dose assessment calculators
developed by the Superfund remedial program. The target audience for this course is site
managers, risk assessors and others that want to obtain a working knowledge on conducting
Superfund radiation risk assessments (February 2016, 382 pages). The background material for
the full One day Classroom course is available at http://semspub.epa.aov/src/document/HQ/100000026.

ESTCP Tool for the Selection of Bioremediation Approaches at Chlorinated Solvent Sites.

ESTCP has developed an easy-to-use tool called BioPIC to facilitate bioremediation
decision-making based on site-specific physical and biogeochemical characteristics. This
research project determined the relationship between biogeochemical parameters and
degradation rates for known degradation pathways of chlorinated ethenes (primarily PCE, TCE,
and daughter products). Data from 90+ sites was used to establish correlations between the
naturally attained rate constant and the abundance of specific parameters. Associations were
then established for parameters such as Dehalococcoides (Dhc) densities, reductase densities,
dissolved oxygen, oxidation-reduction potential, magnetic susceptibility, Fe(ll), Mn(ll), methane,

ethane, total organic carbon, and others. These associations were used to develop a
quantitative framework and decision logic for the screening tool. Based on site-specific
conditions, the tool will provide screening considerations to determine if monitored natural
attenuation (MNA), biostimulation, biologically mediated abiotic reductive dechlorination, or
bioaugmentation is the most appropriate remedial approach. See the BioPIC tool and additional
