Remediation Management of Complex Sites (RMCS-1, 2017), provide a recommended holistic process for management of challenging sites, termed 'adaptive site
management.' By participating in this training course we expect you will learn to apply the ITRC guidance document to: identify and integrate technical and
nontechnical challenges into a holistic approach to remediation; use the Remediation Potential Assessment to identify whether adaptive site management
is warranted due to site complexity; understand and apply adaptive site management principles; develop a long-term performance-based action plan; apply
well-demonstrated techniques for effective stakeholder engagement; access additional resources, tools, and case studies most relevant for complex sites;
and communicate the value of the guidance to regulators, practitioners, community members, and others. For more information and to register, see https://www.itrcweb.org

Sea Level Rise and Resilient Brownfield Revitalization - October 13, 2020, 1:00PM-2:30PM EDT (17:00-18:30 GMT). Sea level rise could cause frequent or
even permanent flooding of coastal brownfield sites, their access roads, or other critical services. These floodwaters can release and spread site contaminants
and debris, endangering the health of the local people and other living things. Brownfield site managers, project staff, and property owners can manage sea
level rise risk and uncertainty with preventive measures, thus reducing the cumulative costs and increasing management and reuse options. This webinar for
EPA staff will introduce brownfield and land revitalization project staff and OLEM colleagues to simple tools to understand how sea level rise can impact a
coastal site. This session will introduce you to steps to screen for and reduce sea level rise risks, and walk through a case study application in Philadelphia,
PA. For more information and to register, see https://clu-in.org/live. ITRC Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment - October 15, 2020, 1:00PM-3:15PM EDT (17:00-19:15 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 https://www.itrcweb.org

1:00PM-3:15PM EDT (17:00-19:15 GMT). After participating in this ITRC training course, the learner will be able to apply ITRC's Decision Making at Contaminated
Sites: Issues and Options in Human Health Risk (RISK-3, 2015) document when developing or reviewing site-specific risk assessments by: identifying common
issues encountered when alternatives to default parameters and scenarios are proposed during the planning, data evaluation, toxicity, exposure assessment,
and risk characterization and providing possible options for addressing these issues; recognizing the value of proper planning and the role of stakeholders
in the development and review of risk assessments; and providing information (that includes links to additional resources and tools) to support decision
making when alternatives to default approaches, scenarios and parameters are proposed. For more information and to register, see https://www.itrcweb.org

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.

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

toluene, ethylbenzene, and xylenes (BTEX) are frequently detected together in groundwater, where they can make their way into drinking water. In situ chemical
oxidation (ISCO) is a common approach used to remove these contaminants from groundwater. This approach uses an oxidizing agent, such as hydrogen peroxide
or persulfate, to trigger a chemical reaction that breaks down the contaminants. While researchers have studied the mechanism by which chemical oxidation
breaks down aromatic compounds, only a fraction of the transformation products have been accounted for in previous research. The NIEHS-funded University
of California, Berkeley Superfund Research Program Center set out to characterize and assess the importance of different chemical pathways responsible
for breakdown of these and related contaminants. View more information at https://tools.niehs.nih.gov/srp/research ...
Separating Anthropogenic Metals Contamination from Background: A Critical Review of Geochemical Evaluations and Proposal of Alternative Methodology
(EPA-600-R-19-196). Meaningful estimates of background contaminant levels are a critical component of site assessments. A request was submitted by the
Ecological Risk Assessment Forum (ERAF) to Ecological Risk Assessment Support Center (ERASC) relating to the issue of background soil chemical demarcation
at metals contaminated sites. Specifically, the request pertained to the validity of an empirical methodology (geochemical association plots) that utilizes
covariation between chemical concentrations and concentrations of major soil elemental constituents (i.e., reference metals) to identify samples that
deviate from “natural” variation. Consequently, a comprehensive investigation of this methodology was conducted and assumes assessments are conducted
with chemical and reference metal data collected from reference sites (i.e., background data) and site-related locations. View or download at https://cfpub.epa.gov/ncea/erasc/recordi ...
Terrestrial Metals Bioavailability: A Literature-Derived Classification Procedure for Ecological Risk Assessment (EPA-600-R-20-042). A request
was submitted by the Ecological Risk Assessment Forum (ERAF) to Ecological Risk Assessment Support Center(ERASC) relating to the issue of terrestrial metals
bioavailability. The ERAF specifically requested a product that characterizes typical aerobic soils in terms of their potential to mitigate metals bioavailability
to soil-dwelling biota. An extensive literature search and corresponding meta-analysis of the empirical data was recommended and performed. The result
is a validated classification procedure, or quantitative tool, that broadly characterizes typical aerobic soils in terms of their potential to sequester
common divalent cationic metal contaminants and mitigate their bioavailability to soil-dwelling biota. It is proposed to augment other ecological risk
assessment approaches and risk-based remediation of metals contaminated soils.View or download at https://cfpub.epa.gov/ncea/erasc/recordi ...
