Upcoming Live Internet Seminars
ITRC Geophysical Classification for Munitions Response - August 9, 2016, 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.

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - August 30, 2016, 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.

Protecting Pollinators through Sustainable Superfund Reuse - September 8, 2016, 2:00PM-3:30PM EDT (18:00-19:30 GMT).
In recent years, declines in pollinator populations and honey bees in particular, have raised concerns about the impacts to agricultural supply and ecosystem sustainability.
EPA has engaged in a federal partnership with the United States Department of Agriculture to minimize impacts of pesticides on pollinator populations.
But EPA has also engaged with organizations such as the Pollinator Partnership to support the development and maintenance of pollinator habitat.
This webinar will highlight the opportunities presented to support pollinators through sustainable and conscientious reuse of Superfund sites and other blighted properties.
Speakers will share case study examples of pollinator habitat on contaminated sites, as well as some available resources to aid in supporting pollinators at a site near you.

Superfund Research Program Research Brief 259: Phytostabilization of Mine Tailings with Compost-Assisted Direct Planting.
Amending mine waste with compost is a viable and promising alternative to the expensive process of covering an entire site with a thick soil or rock cap followed by seeding, according to research from the University of Arizona Superfund Research Program (UA SRP) Center.
A recent field study at the Iron King Mine and Humboldt Smelter Superfund site showed that adding amendments and seeds led to establishment of native plants and sustained growth on mine tailings over 4 years.
The trial was based on successful results from preliminary greenhouse studies, which scaled effectively to the field.

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - ITRC 2-day Classroom Training, Somerset, NJ, September 26-27, 2016 AND Framingham, MA, November 9-10, 2016.
Preapproved for continuing education for CT LEPs, MA LSPs, NJ LSRPs, and SC PGs.
This 2-day ITRC classroom training is based on the ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and led by internationally recognized experts.
Within the training class - hear about EPA's Technical Guide For Addressing Petroleum Vapor Intrusion At Leaking Underground Storage Tank Sites (June 2015).
The ITRC guidance document and EPA guide are complementary documents with the ITRC training course providing the "how-to" knowledge and skills for screening, investigating, and managing the petroleum vapor intrusion pathway.
The class will enable you to develop the skills to screen-out petroleum sites based on the scientifically-supported ITRC strategy and checklist; focus the limited resources investigating those PVI sites that truly represent an unacceptable risk; and communicate ITRC PVI strategy and justify science-based decisions to management, clients, and the public.
Interactive learning with classroom exercises and Q&A sessions will reinforce these course learning objectives.
For local, state, and federal government; students; community stakeholders; and tribal representatives, ITRC has a limited number of scholarships (waiver of registration fee only) available.
