Human Health and the Environment. The U.S. EPA, as part of its Science to Achieve Results (STAR) program, is seeking applications proposing research that will
lead to: (1) better understanding and characterization of the types and quantities of current and historical per- and poly-fluoroalkyl substances (PFAS)
and PFAS-containing waste associated with waste disposal (e.g., landfills), as well as media containing PFAS released from these activities (e.g., PFAS
in leachate collected by landfills or PFAS leaching to subsurface soils and groundwater); (2) increased knowledge of the fate, transport, potential for degradation
or other changes to PFAS, and their mobility during materials management (e.g., under different landfill conditions such as pH, temperature, moisture content)
that facilitate or retard such transformation or movement; and (3) new or improved methods that are more effective, efficient (in cost, energy, etc.), and
practical in controlling, treating, destroying, or removing PFAS in waste and wastewater, landfill leachates, biosolids, or environmental media. The main
goal is to promote innovation in evaluating and managing PFAS in solid waste, landfills, and environmental media that will lead to improved decision making,
management practices, and technical methods to minimize the risks to both humans and ecosystems. Applications are due by October 2, 2018. For more information

water bodies adjacent to sites with contaminated groundwater may receive impacts that impair otherwise functional ecosystems and create new exposure pathways,
increasing human health risks. Optimizing site characterization protocols to improve the remedy design effort is best achieved by developing knowledge
of the potential extent and magnitude of contaminated groundwater discharge into the surface water body. Through field-based research, EPA's Office of Research
and Development has developed several approaches to more reliably characterize system hydrology and assess contaminant flux. A series of standard methods
and spreadsheet-based calculation tools have been developed to facilitate data collection and analysis, and all in an affordable and consistent manner.
A case study example will be used to highlight these novel approaches to improve understanding of the spatial and temporal dynamics of contaminant transport
across the groundwater-surface water transition zone. For more information and to register, see https://clu-in.org/live. ITRC Characterization and Remediation of Fractured Rock - September 11, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The basis for this training course
is 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

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) 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: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1,
2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background,
compliance, trend analysis, and monitoring optimization. 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. For more information and to register, see http://www.itrcweb.org
or https://clu-in.org/live. ITRC Geophysical Classification for Munitions Response - September 18, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). This training class and supporting
guidance document explain the process of geophysical classification, describe its benefits and limitations, and discuss the information and data needed
by regulators to monitor and evaluate the use of the technology. This document and training also emphasize using a systematic planning process to develop data
acquisition and decision strategies at the outset of a munitions response effort, as well as quality considerations throughout the project. Stakeholder
issues that are unique to munitions response are also discussed. After this training class, participants will: understand the technology and terminology,
be ready to engage in the planning process to address quality considerations throughout a project, find tools to transfer knowledge within organizations
and to stakeholders, and start to transition mindset to decisions that leave non-hazardous items in the ground. An audience who understand current munitions
response tools and procedures (for example, geophysical surveys, sensors, data analysis) will benefit most from this document and training. For more information
and to register, see https://www.itrcweb.org or https://clu-in.org/live. ITRC Geospatial Analysis for Optimization at Environmental Sites - September 20, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). 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 life-cycle stage, identify optimization questions where geospatial methods can contribute
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;
and use the project manager's tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently
in decision making. For more information and to register, see http://www.itrcweb.org or https://clu-in.org/live. ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - September 25, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT).
Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI)
occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate
indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor
intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids
(LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. The ITRC
Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014)
and this associated Internet-based training provide regulators and practitioners with consensus information based on empirical data and recent research
to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident
decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology
for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision
making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway
can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

A memorandum entitled 'Superfund Task Force Recommendation #3: Broaden the Use of Adaptive Management' was completed by EPA on July 3rd, 2018 which provided
Superfund's working definition of Adaptive Management and outlined an implementation plan to expand Adaptive Management s use at Superfund sites. Per the
implementation plan, EPA is in the process of seeking input on the pilot criteria with separate input from EPA, States/Tribes, and other stakeholders. This
webinar is to provide stakeholders an overview of the Task Force Adaptive Management Implementation Plan and pilot criteria to support their review of the
pilot criteria out for comment. For more information and to register, see https://clu-in.org/live. ITRC Integrated DNAPL Site Characterization - October 2, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The Integrated DNAPL Site Characterization Team
has synthesized the knowledge about dense nonaqueous phase liquid (DNAPL) site characterization and remediation acquired over the past several decades,
and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource
to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts
related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able
to use the guidance to develop and support an integrated approach to DNAPL site characterization, including: identify what site conditions must be considered
when developing an informative DNAPL conceptual site model (CSM); define an objectives-based DNAPL characterization strategy; understand what tools and
resources are available to improve the identification, collection, and evaluation of appropriate site characterization data; and navigate the DNAPL characterization
tools table and select appropriate technologies to fill site-specific data gaps. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live.

Highlight from the CLU-IN Seminar Archives. Each edition of TechDirect highlights a previously recorded internet seminar from our archives that may be
of interest to our readers. We welcome your feedback on this addition to TechDirect. Frequently-Asked Questions about Monitored Natural Attenuation in Groundwater, Sponsored by: Environmental Security Technology Certification Program
(ESTCP), Archive of June 13, 2014 Seminar (2 hours). The talk highlighted a 2014 guidance document using the Frequently Asked Questions (FAQs) format to provide
a concise overview of current knowledge regarding management of subsurface contaminant releases using monitored natural attenuation (MNA). The envisioned
audience includes state regulators, federal regulators, industry, consultants, DoD staff, and members of the local community involved in selecting remedies
for contaminated sites. The intended value of the document is to provide current knowledge in support of sound decisions. In the interest of brevity, the FAQs
assume that the reader has a general understanding of hydrogeology, the movement of chemicals in porous media, remediation technologies, and the remedy selection
process. For more information or to replay, visit https://clu-in.org/conf/tio/FAQMNA_06131 ... > New Documents and Web Resources Activated Carbon-Based Technology for In Situ Remediation Focus Area. Activated carbon (AC)-based technology involves emplacement of AC-based amendments
for in situ remediation of soil and groundwater. Besides AC, amendments typically include other reactive products commonly used with in situ remediation
technologies, such as in situ chemical reduction (ISCR), in situ chemical oxidation (ISCO), and bioremediation. The technology is commonly referred to as
'carbon-based injectate' (CBI), especially for remediation of petroleum hydrocarbons. AC-based amendments remove contaminant via two processes: adsorption
by AC and degradation by reactive amendments. The coupling of adsorption and degradation makes this technology a promising remedial option for addressing
persistent plumes emanating from contaminants sorbed on soil, residual non-aqueous phase liquid (NAPL), or mass stored in low-permeability zones. The technology
might also be applicable near or at the source area, especially when combined with other source treatment remedies, to limit contaminant mass flux out of source
zones to downgradient plumes. View and use at https://clu-in.org/ac. Technology Innovation News Survey Corner. The Technology Innovation News Survey contains market/commercialization information; reports on demonstrations,
