SRI Webinar Series: Potentially Responsible Party (PRP) Perspectives on
Superfund Site Reuse - August 13, 2015, 2:00PM-4:00PM EDT (18:00-20:00 GMT).

A potentially responsible party, or PRP, is an individual or company that is potentially
responsible for contamination problems at a Superfund site. Whenever possible, EPA
requires PRPs to clean up hazardous waste sites the PRP may have contaminated.
Many PRPs not only perform the cleanup, but also seek ways to return the site to
beneficial use for the community and maximize the extent of land use on the site.
Presenters on this webinar will include representatives from several PRP groups who
have taken an active role in facilitating the beneficial use of sites they manage and who
have worked collaboratively with EPA over many years to ensure that both the cleanup
and the reuse of the property remain protective of human health and the environment.

ITRC Issues and Options in Human Health Risk Assessment - A Resource When
Alternatives to Default Parameters and Scenarios are Proposed - August 20,
2015,1:00PM-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

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and
Management - August 27, 2015, 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 provides
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. For more information and to

ITRC Groundwater Statistics for Environmental Project Managers - September 3,
2015,1:00PM-3:15PM EDT (17:00-19:15 GMT). 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) 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
