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. For more information and to register, see http://clu-in.org/live.

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 register, see http://www.itrcweb.org or http://clu-in.org/live.

Progress in Research: TCE, PCBs, and Phthalates - Exposure, Mechanisms of Disease, and Clean-Up Remedies - August 24, 2015, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from two SRP Centers. Researchers at the Northeastern University SRP Center are studying chlorinated solvents and phthalates, contaminants that could be linked to high preterm birthrates in Puerto Rico. The University of Kentucky SRP Center explores how nutrition and exercise might offer protection from polychlorinated biphenyl (PCB) toxicity and are developing new sustainable remediation approaches using nanotechnology. For more information and to register, see http://clu-in.org/live.

Analytical Chemistry Data Review - Volatile Organics Data - August 26, 2015, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar will cover review and validation of Volatile Organics data.

The data review process and documentation will be discussed using the 2014 National Functional Guidelines for Superfund Organic Methods Data Review. Participants will be asked to review a data package prior to the live webinar. For more information and to register, see http://clu-in.org/live.

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 register, see http://www.itrcweb.org or http://clu-in.org/live.

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.

SRP Research Brief 247: PCE in Drinking Water Linked to Cancer and Epilepsy. Early-life exposure to tetrachloroethylene (PCE; perchloroethylene) in drinking water may increase the risk of epilepsy and certain types of cancer into adulthood, according to Boston University Superfund Research Program (BU SRP) Center researchers. PCE is a solvent frequently used in dry cleaning solutions, adhesives, metal degreasers, and other commercial products. For more information, see http://tools.niehs.nih.gov/srp/researchbriefs/view.cfm?Brief_ID=247. To get monthly updates on research advances from the SRP you can subscribe to their Research Brief mailing list at https://list.nih.gov/cgi-bin/wa.exe?SUBED1=SRP-BRIEF&A=1.
