FFRRO Five Year Review Tools

The Interagency Workgroup on Five-Year Reviews will showcase the training module "CERCLA Five-Year Review Training-A Guide for Writers and Reviewers at Federal Facilities" and a guide for writing an Executive Summary for federal facility five-year reviews. These tools were developed through a collaborative effort by EPA, Department of Defense and its components, Department of Energy and Department of Interior. The training module is a tool to help improve the federal agency site manager's understanding of what information and data are needed to determine whether the remedy remains protective of human health and the environment. By writing more concise reports, the review and approval time by the regulators will be reduced. The guide for the Executive Summary is an agreed upon format for federal facilities. The guide will help site managers organize and summarize the report in a succinct and easy to understand document for the public.

Superfund Redevelopment Initiative Series: Restoring Superfund Sites to Public Good

Superfund sites can be reused in many ways, but many local governments are seeing unique opportunities to use sites for public or local government purposes. From roads to firefighting training facilities, local governments who own or acquire Superfund sites are finding ways to put these properties to good use.

Superfund Redevelopment Initiative Series: Opportunities for Reuse at Capped Sites

Former landfills, abandoned dumps, and other contaminated sites throughout the United States, once thought to be of limited value, are being transformed into viable commercial and industrial developments, parks and other recreational areas, and wildlife areas. With forethought and effective planning, communities and site stakeholders can return sites to productive use without jeopardizing the effectiveness of a remedial cap. This webinar will share lessons learned from the successful reuse and assessment of capped sites.

Superfund Redevelopment Initiative Series: Highlighting Beneficial Economic Impacts at Superfund Sites

Site redevelopment can revitalize a local economy with jobs, new businesses, tax revenues and local spending. This webinar will showcase new economic case studies across the country with different types of development- large and small, commercial and public, even new transportation options to show how they can all have beneficial impacts on the surrounding community.

Analytical Tools and Methods: Session I - Field-ready Biosensors to Assess Bioavailability and Toxicity

This webinar series highlights innovative analytical tools and methods developed and used by Superfund Research Program (SRP) grantees. The presenters will feature the benefits of these new tools and methods compared to conventional methods. They also will include information about how the technology has helped to facilitate ongoing SRP research.

In the first session, researchers will describe their tools to assess bioavailability/toxicity for more effective human and/or environmental monitoring. Treatment assessments and water quality monitoring that rely only on measuring the reduction of target contaminant concentrations are often insufficient because they do not consider the complex and broader risks that specific contaminants or mixtures and their transformation products pose to the environment and human health.

Michael Unger, Ph.D., Professor of Marine Science at the Virginia Institute of Marine Science, will discuss his work on advances in biosensor technology that allows near real-time measurement of contaminants at sub parts-per-billion (ppb) concentrations in small volume (< 5 mL) aqueous samples. Polycyclic aromatic hydrocarbon (PAH) concentrations can be measured in the field within minutes after collection to map the spatial distribution of PAHs at contaminated sites and to assess the bioavailable or toxic fraction within sediments. Correlations between PAH concentrations measured by the biosensor and those measured by gas chromatography - mass spectrometry (GC-MS) were excellent, and the results are now being used to help evaluate sediment remediation strategies.

April Gu, Ph.D., Professor of Civil and Environmental Engineering at Northeastern University, will discuss her work to develop a novel, feasible, and cost-effective quantitative toxicogenomics-based toxicity assessment platform for high-throughput and effective chemical hazardous identification and environmental toxicity monitoring. Gu also will describe how she and her team systematically optimized the assay platform, evaluated its robustness and performance, validated the assay output, and demonstrated its wide applications.

Natalia Vasylieva, Ph.D., and Bogdan Barnych, Ph.D., postdoctoral researchers at the University of California, Davis, will discuss how they choose target analytes for immunoassay analysis. They also will introduce nanobodies as novel and exciting reagents for immunoassay-based biosensors. The second part of the presentation will focus on examples of immunoassay application for human and environmental monitoring, as well as their application in biosensors.

Analytical Tools and Methods: Session II - Techniques for Trace Analysis of Metals and Chemical Metabolites

This webinar series highlights innovative analytical tools and methods developed and used by Superfund Research Program (SRP) grantees. During the second session of the series, speakers will highlight techniques that help measure trace levels of metals and chemical metabolites in order to better understand environmentally relevant chemical exposures. Presenters include: Tracy Punshon, Ph.D., Dartmouth SRP Center; Bruce Buchholz, Ph.D., Lawrence Livermore National Laboratory, University of California, Davis SRP Center; and Lee Ferguson, Ph.D., Duke University SRP Center.

Groundwater Statistics for Environmental Project Managers

Interstate Technology Regulatory Council 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, http://www.itrcweb.org/gsmc-1/) 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:

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.

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management

Interstate Technology Regulatory Council 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. Fortunately, in the case of PHC vapors, this migration is often limited by microorganisms that are normally present in soil. The organisms consume these chemicals, reducing them to nontoxic end products through the process of biodegradation. The extent and rate to which this natural biodegradation process occurs is strongly influenced by the concentration of the vapor source, the distance the vapors must travel through soil from the source to potential receptors, and the presence of oxygen (O2) in the subsurface environment between the source and potential receptors.

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.

After attending this ITRC Internet-based training, participants should be able to:
  • Determine when and how to use the ITRC PVI document at their sites
  • Describe the important role of biodegradation impacts on the PVI pathway (in contrast to chlorinated solvent contaminated sites)
  • Value a PVI conceptual site model (CSM) and list its key components
  • Apply the ITRC PVI 8 step decision process to screen sites for the PVI pathway and determine actions to take if a site does not initially screen out, (e.g., site investigation, modeling, and vapor control and site management)
  • Access fact sheets to support community engagement activities at each step in the process
For reference during the training class, participants should have a copy of the flowcharts, Figures 1-2, 3-2, and 4-1 from the ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and are available as a 3-page PDF at http://www.cluin.org/conf/itrc/PVI/ITRC-PVI-FlowCharts.pdf


ITRC also offers a 2-day PVI focused classroom training at locations across the US. The classroom training provides participants the opportunity to learn more in-depth information about the PVI pathway and practice applying the ITRC PVI guidance document with a diverse group of environmental professionals.

Geospatial Analysis for Optimization at Environmental Sites

Interstate Technology Regulatory Council Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation. The results of geospatial analyses add additional lines of evidence to decision making in optimization opportunities in environmental sites across all project life cycle stages (release detection, site characterization, remediation, monitoring and closure) in soil, groundwater or sediment remediation projects for different sizes and types of sites.

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 lifecycle stage, identify optimization questions where geospatial methods can contribution 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
  • Use the project managerís tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently in decision making
