> Upcoming Live Internet Seminars ITRC Connecting the Science to Managing LNAPL Sites a 3 Part Series - November 6 and 13, 2018 (Part 1 presented on October 30) . The newly updated LNAPLs (Light
Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial
Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you: build upon your understanding of LNAPL behavior
in the subsurface (Part 1), develop your LNAPL conceptual site model and LNAPL remedial goals (Part 2), and select/implement LNAPL technologies (Part 3).
After this training series, the expectation is that you will have the skills and understanding to use ITRC science-based resources to improve decision making
at your LNAPL sites. For regulators and other government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs.
It is expected that participants will attend this 3-part training series in sequence. For more information and to register, see
or NARPM Presents?Introduction to Near Surface Environmental Geophysics Webinar - A Practical Guide for Commonly Used Methods and Applications - November
8, 2018, 1:00PM-3:00PM EST (18:00-20:00 GMT). This webinar will present a general overview of several geophysical methods which are commonly used at environmental
waste sites. The primary focus will be keyed to practical applications of each method. Geophysical tools will be presented in a manner so that the participant
will be able to identify each tool by its physical appearance, what properties are measured, how information is collected and processed, method detection
limits, how to select the most effective method, methods that complement each other, and situations where some methods will not work. Also presented are details
on how to plan or manage a geophysical survey which include gathering information to properly customize a survey to detect alleged targets. A brief introduction
will also be given for a few basic borehole geophysical tools specifically for shallow two-inch diameter monitoring wells to optimize information gathering
during well construction and for long term monitoring. Examples of surface and borehole information will conclude the webinar. For more information and to
register, see Chlorinated Solvent Bioremediation: Fundamentals and Practical Application for Remedial Project Managers - November 14, 2018, 1:00PM-2:30PM EST (18:00-19:30
GMT). Anaerobic reductive dechlorination (ARD) can be used to cost-effectively remediate chlorinated solvent sites. In ARD, microbial communities use
substrates to sequentially degrade chlorinated solvents such as trichlorethylene (TCE). Depending on conditions at a site, remediation may involve adding
substrates (biostimulation) and/or dechlorinating organisms (bioaugmentation). This presentation will discuss the biological and chemical principles
of this technology and is geared toward remedial project managers. Key considerations for site specific application will be covered. In addition, case studies
will provide examples of data from sites displaying ARD as well as sites with poor performance or insufficient data. For more information and to register, see
Groundwater/Surface Water Interactions: Developing Conceptual Site Models of Organism Exposures in Hyporheic Systems - November 16, 2018, 11:30AM-6:30PM
EST (16:30-23:30 GMT). This training workshop will present an overview of the relationships and interactions between groundwater and surface water bodies,
giving participants a greater understanding of potential exposure scenarios. Discussions will focus on developing effective conceptual site models and
how to collect useful data from the hyporheic zone, with case study examples. The training will end with a panel discussion and direction to EPA resources. This
workshop's content is directed toward Federal, State, Tribal, and University-level scientists, particularly hydrogeologists, ecologists, risk assessors,
remedial project managers (RPMs), National Environmental Policy Act (NEPA) project reviewers, Tribal Specialists, EPA Superfund Technical Liaisons (STLs),
EPA Regional Science Liaisons (RSLs), EPA Regional Science Councils (RSCs), and those involved with underground storage tanks. For more information and

(18:00-19:30 GMT). Per- and poly-fluoroalkyl Substances (PFAS) contamination of groundwater sources in the U.S. is a widespread problem for the drinking
water industry. Well water supplies in the municipalities of Fountain, Security, and Widefield, Colorado, contain Perfluorooctanoic Acid (PFOA) and Perfluorooctane
Sulfonate (PFOS) greater than U.S. Environmental Protection Agency (EPA) health advisory level of 70 nanograms/liter (ng/L). The source of PFAS in the well
water has been associated with aqueous film forming foam (AFFF) at Peterson Air Force Base (AFB). Several public water systems and numerous private well owners
use the impacted Widefield Aquifer as their sole source of drinking water. To assist property owners and limit exposure of PFAS in residential drinking water
systems, treatability studies were conducted by EPA on the PFAS removal effectiveness of commercially available Point-of-Use (POU)/Point-of-Entry (POE)
units using Reverse Osmosis (RO) treatment and Granular Activated Carbon (GAC) adsorbents. Household water systems were tested with a representative test
water with the water quality characteristics and six PFAS contaminants found in Widefield Aquifer region groundwater samples. The study also documented
the ease of use during installation, startup, and continuous/intermittent operation of the water systems. For more information and to register, see
ITRC Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment - November 27, 2018, 1:00PM-3:15PM EST (18:00-20:15 GMT).
The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1).
This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate
bioavailability into the human health risk assessment process. The target audience for this guidance and training course are: project managers interested
in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs, and risk assessors new to bioavailability or those who want
additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human
health risk at a contaminated site. As a participant in this training you should learn to: apply the decision process to determine when a site-specific bioavailability
assessment may be appropriate, use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability, consider factors
that affect arsenic, lead and PAH bioavailability, select appropriate methods to evaluate soil bioavailability, and use tools to develop site-specific
soil bioavailability estimates and incorporate them into human health risk assessment. For more information and to register, see
or ITRC Long-term Contaminant Management Using Institutional Controls - Nov 29, 2018, 1:00PM-3:15PM EST (18:00-20:15 GMT). Institutional controls (ICs)
are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure
to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC's Long-term Contaminant
Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including
monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible
for the management and stewardship of ICs. After attending the training, participants will be able to: describe best practices and evolving trends for IC management
at individual sites and across state agency programs; use this guidance to improve IC reliability and prevent IC failures, improve existing, or develop new,
IC Management programs, identify the pros and cons about differing IC management approaches; use the tools to establish an LTS plan for specific sites; and
use the elements in the tools to understand the information that should populate an IC registry or data management system. For more information and to register,

the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too
complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated
porous media, yet there are important differences. By participating in this training class, you should learn to use ITRC's Fractured Rock Document to guide
your decision making so you can: develop quality Conceptual Site Models (CSMs) for fractured rock sites, set realistic remedial objectives, select the best
remedial options, monitor remedial progress and assess results, and value an interdisciplinary site team approach to bring collective expertise to improve
decision making and to have confidence when going beyond containment and monitoring -- to actually remediating fractured rock sites. For more information

of interest to our readers. We welcome your feedback on this addition to TechDirect. Mining Waste Treatment Technology Selection, Sponsor Interstate Technology and Regulatory Council, Archive of May 20, 2014 Seminar (2 Hours, 15 Minutes).
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. To replay the archived webinar, visit ... . > New Documents and Web Resources New Mining Sites Issue Area Section on Developing a Watershed Partnership. The Characterization, Cleanup, and Revitalization of Mining Sites issue area
has a new section devoted to creating and fostering partnerships to address mining sites on a watershed basis. Addressing sites separately could result in
inefficient or incomplete cleanups. However, by developing a partnership among watershed stakeholders, a more holistic and comprehensive cleanup and restoration
of the watershed can be achieved. The Federal Mining Dialogue, whose members represent 14 federal agencies, formed the Watershed and Partnerships Working
Group to create and share materials that may be useful in developing and maintaining partnerships. These materials and other resources are available for download

from sediments into the aquatic food web, according to a new Superfund Research Program (SRP) study. Researchers discovered high concentrations of arsenic
in the water and plankton of well-mixed shallow lakes. The water in shallow lakes warms more uniformly that in deep, thermally stratified lakes, enabling these
lakes to remain well-mixed with only brief periods of stratification. According to the study by University of Washington (UW) SRP Center researchers, this
mixing leaves more of an opportunity for arsenic in the sediments to move up into the overlying water and enter the aquatic food web. For more information, see ...
