Updates on Renewable Energy Development on Contaminated Land: Community Involvement and Useful Informational Tools

This session will provide federal and state regulators, environmental consultants, site owners and community stakeholders with a quick overview accompanied by real world applications of renewable energy development on contaminated sites with a focus on community involvement on Superfund sites.

This hour session will include:
  • Analysis of current or successful renewable energy development projects on contaminated sites and the associated community involvement issues
  • Conclusions from discussions with community involvement coordinators regarding renewable energy development on Superfund sites
  • Introduction to the current mapping and informational tools available to generally assess renewable energy potential and resources
  • Contributions to the presentation by various experts who will also be available for the question & answer session after the main presentation
This session is intended for general audiences, however a basic understanding of the EPA's RE-Powering America's Land initiative is recommended.

Triad Month Session 3: Triad During RD/RA

A little over a year ago, over 260 individuals gathered from the U.S. and abroad at UMass-Amherst in Massachusetts to discuss the use of the Triad Approach to conduct investigations and remedial actions faster, better, and at a reduced cost. The Triad Community of Practice (CoP) decided to update and repackage several of those same sessions to benefit the greater CLU-IN audience that either may not have been able to attend the conference, or were not able to attend a specific presentation while at the conference. By doing this, we hope you too can learn more about some of the Triad tools and how they have been applied by your colleagues in the environmental industry.

Today's session is the third in a series of seven sessions collectively comprising Triad Month on CLU-IN. This two-hour session will look to dispel the common perception that Triad is simply a tool used during characterization. To meet that objective, we will be re-delivering two of the selected presentation from the June 2008 conference on this topic. The first is a case study involving Seymour Johnson AFB in North Carolina, where future first planning, Triad techniques, and performance-based contracting strategies were employed to accelerate site closure. The second is a demonstration of one of the many useful tools in the Triad toolbox — Spatial Analysis and Decision Assistance (SADA). In addition to learning more about SADA, the instructor will use a removal action to demonstrate the use of this useful Triad technique.

Triad Month Session 4: Triad Measurement Techniques

A little over a year ago, over 260 individuals gathered from the U.S. and abroad at UMass-Amherst in Massachusetts to discuss the use of the Triad Approach to conduct investigations and remedial actions faster, better, and at a reduced cost. The Triad Community of Practice (CoP) decided to update and repackage several of those same sessions to benefit the greater CLU-IN audience that either may not have been able to attend the conference, or were not able to attend a specific presentation while at the conference. By doing this, we hope you too can learn more about some of the Triad tools and how they have been applied by your colleagues in the environmental industry.

Today's session is the fourth in a series of seven sessions collectively comprising Triad Month on CLU-IN. In two successive presentations, this two-hour session will examine the use of Triad measurement techniques. The first presentation by Seth Pitkin of Stone Environmental, "High Resolution Groundwater Characterization Methods and the Triad Approach," examines the principle of reducing sampling uncertainty as an essential element in reducing the uncertainty associated with key site management decisions. The second offering by Dr. Mark Kram of Groundswell Technologies, Inc., "Hydraulic Parameter and Mass Flux Distribution Using the High-Resolution Piezocone and GMS," will demonstrate the use of the high-resolution piezocone direct push sensor probe to determine direction and rate of ground water flow in three dimensions.

Triad Month Session 5: Triad Implementation

A little over a year ago, over 260 individuals gathered from the U.S. and abroad at UMass-Amherst in Massachusetts to discuss the use of the Triad Approach to conduct investigations and remedial actions faster, better, and at a reduced cost. The Triad Community of Practice (CoP) decided to update and repackage several of those same sessions to benefit the greater CLU-IN audience that either may not have been able to attend the conference, or were not able to attend a specific presentation while at the conference. By doing this, we hope you too can learn more about some of the Triad tools and how they have been applied by your colleagues in the environmental industry.

Today's session is the fifth in a series of seven sessions collectively comprising Triad Month on CLU-IN. In two successive presentations, this 1.5-hour session will examine the implementation of Triad principles and processes. The first presentation by Nick Nigro of ECCS Nationwide Mobile Laboratories, "Programmatic Implementation of the Triad Approach within a State Reimbursement Program" presents the successful experience of the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) program to remediate local agricultural supply dealerships using the Triad approach. Sharon Budney of CDM is making the second presentation, "Effective Funding Management Approaches for Triad Investigations." This presentation describes successful funding and budget management approaches used to implement the Triad approach during the remedial investigation at the Emmell's Septic Landfill Superfund Site located in Galloway Township, New Jersey.

Triad Month Session 6: Triad Case Studies

A little over a year ago, over 260 individuals gathered from the U.S. and abroad at UMass-Amherst in Massachusetts to discuss the use of the Triad Approach to conduct investigations and remedial actions faster, better, and at a reduced cost. The Triad Community of Practice (CoP) decided to update and repackage several of those same sessions to benefit the greater CLU-IN audience that either may not have been able to attend the conference, or were not able to attend a specific presentation while at the conference. By doing this, we hope you too can learn more about some of the Triad tools and how they have been applied by your colleagues in the environmental industry.

Today's session is the sixth in a series of seven sessions collectively comprising Triad Month on CLU-IN. During this two-hour session, two Triad practitioners will present case studies of the Triad approach. In the first case study, "Characterizing a Complex TCE Groundwater Plume, Eliminating Suspected Source Areas, and Reducing Investigation Costs for a RCRA RFI at Shaw AFB, SC," Jonathan Shireman of Shaw Environmental & Infrastructure, will demonstrate how the Triad approach was successfully used to complete a RCRA Facility Investigation in a complex geologic setting with highly sensitive land use at Shaw Air Force Base. For the second case study, Kym Takasaki with the U.S Army Corp of Engineers, will present a case study on "Using Environmental Visualization System (EVS) Modeling to Develop Remediation Alternatives."

Triad Month Session 7: Dynamic Work Strategies

A little over a year ago, over 260 individuals gathered from the U.S. and abroad at UMass-Amherst in Massachusetts to discuss the use of the Triad Approach to conduct investigations and remedial actions faster, better, and at a reduced cost. The Triad Community of Practice (CoP) decided to update and repackage several of those same sessions to benefit the greater CLU-IN audience that either may not have been able to attend the conference, or were not able to attend a specific presentation while at the conference. By doing this, we hope you too can learn more about some of the Triad tools and how they have been applied by your colleagues in the environmental industry.

Today's session is the seventh (and last) in a series of seven sessions collectively comprising Triad Month on CLU-IN. During this two-hour session, two Triad practitioners will present case studies of the Triad approach. In the first case study, "Real Time CSM Visualization and Feedback," Mr. John Sohl of Columbia Technologies will demonstrate concepts as well as case studies regarding one of the most challenging aspects of the Triad toolbox — that being able to both process large data sets as well as incorporate them into an evolving CSM, visually, so that both onsite and offsite project stakeholders can "see" the current investigation status. The second case study takes those concepts up a notch in terms of volume of data to manage and the duration of the program of interest. Between these two presentations, you will be better equipped prior to your next project planning process of potential means to manage data onsite and convert empirical 2-D results into more useable formats.

Collaborative Research on Environmental Toxicants in Rapidly Developing Settlements of the U.S.-Mexico Border

This project aims to improve environmental public health in the San Diego-Tijuana city-region. The objective is twofold: (1) develop new watershed-based strategies/models that can help the National Institute of Environmental Health Sciences (NIEHS) address Global Environmental Health (GEH), and (2) share the science and technology contributions of UCSD's Superfund Basic Research Program (SBRP) with urban-regional planning scholars, educators and professionals who are struggling to better understand how problems of the built environment, land use and pollution impact environmental public health. The geographic unit of analysis is Los Laureles Canyon-a representative sub-basin of the Tijuana River Watershed spanning the US-Mexico border. More than 80,000 people live in the colonias of Los Laureles Canyon on the Mexican side of the border. Colonias are large irregular human settlements that lack many basic urban services. Accelerated population growth in Los Laureles Canyon has led to chronic problems of sediment, trash and hazardous waste flows into the U.S. coming from Mexico. The inadequate management of sewage, hazardous substances and solid wastes poses chronic risks of exposure to pathogens and environmental toxicants to communities on both sides of the border. Two specific questions motivate this effort: (1) What is the degree of contamination by Superfund toxicants (PAHs, PCBs and Dioxins and heavy metals) in the soils and sediments of Los Laureles Canyon? and (2) What factors can be used to predict the spatial distribution of contaminants at the sub-watershed and watershed scale? The collection and analysis of these data will help us understand what natural, built environment and human activity factors along the Mexican side of the Tijuana River Watershed contribute to presence/distribution of Superfund chemicals in soil and sediments. In turn, this effort will help identify and prioritize ecological and human health risks in the City of Tijuana and in the binational Tijuana River Watershed, while informing the selection of strategies to reduce or eliminate present and future exposure(s) to Superfund chemicals on both sides of the border. This effort is enabling us to: 1) work with binational stakeholders in an unprecedented crossborder data collection effort focused on Superfund toxicants, 2) relate the environmental health sciences to urban planning and the multiple stressors and risk factors facing fast-growing low income human settlements along the U.S.-Mexico border, and 3) improve our capacity for science communication.

Phytotechnologies

Interstate Technology Regulatory Council Phytotechnologies is a set of technologies using plants to remediate or contain contaminants in soil, groundwater, surface water, or sediments. These technologies have become attractive alternatives to conventional cleanup technologies due to relatively low capital costs and the inherently aesthetic nature of planted sites.

This training familiarizes participants with ITRC's Phytotechnology Technical and Regulatory Guidance and Decision Trees, Revised (Phyto-3, 2009). This document provides guidance for regulators who evaluate and make informed decisions on phytotechnology work plans and practitioners who have to evaluate any number of remedial alternatives at a given site. This document updates and replaces Phytoremediation Decision Tree (Phyto-1, 1999) and Phytotechnology Technical and Regulatory Guidance Document (Phyto-2, 2001). It has merged the concepts of both documents into a single document. This guidance includes new, and more importantly, practical information on the process and protocol for selecting and applying various phytotechnologies as remedial alternatives.

This guidance contains decision trees:
  • Remedy Selection Decision Tree
  • Groundwater Decision Tree
  • Soil/Sediment decision Tree
  • Riparian Zone Decision Tree

This course will be most useful to you if you download the guidance and follow the discussion with the Decision Trees displayed in your guidance. Our instruction is how to use the Guidance - not how to use the decision trees process. That is explained within the Guidance.

Enhanced Attenuation of Chlorinated Organics: A Site Management Tool

Interstate Technology Regulatory Council Many sites with chlorinated organic contamination in groundwater have gone through extensive remedial evaluations and actions. After years of operating high energy processes, their effectiveness has begun to diminish without remedial objectives being met. Other effective remedial alternatives can be applied; however, there are difficulties transitioning these sites from these high energy systems to other low energy remedial alternatives and eventually to Monitored Natural Attenuation (MNA).

This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process.

As our experience and knowledge grows around the implementation of MNA, the EA process will be considered an important management tool for optimizing site remedies and moving sites to final completion. This approach is consistent with the current regulatory environment and can be accommodated within a broad range of regulatory programs such as CERCLA and State dry cleaner regulations. This new framework and decision process will accelerate the environmental clean-up progress on a national scale and reduce overall costs, while still providing protection to human health and the environment.

For reference during the training class, participants should download and print a copy of the decision flow chart, Figure 2-1 on page 10 of the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/eaco/ITRC-EACO-DecisionFlowchart.pdf.

In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones

Interstate Technology Regulatory Council Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators can use to objectively assess, monitor, and optimize ISB treatment of DNAPL source zones. The objective is to provide adequate technology background for the user to understand the general and key aspects of ISB for treatment of chlorinated ethene DNAPL source zones. It is not intended to be a step-by-step instruction manual for remedial design, but describes technology-specific considerations for application of ISB of DNAPL source zones.

For this training and guidance document, a DNAPL source zone includes the zone that encompasses the entire subsurface volume in which DNAPL is present either at residual saturation or as "pools" that accumulate above confining units. The DNAPL source zone includes regions that have come into contact with DNAPL and may be storing contaminant mass as a result of diffusion of DNAPL into the soil matrix. Even though DNAPLs may be present in both the unsaturated and saturated zones, the discussion of ISB of DNAPL source zones in this training and guidance document focuses on treatment of DNAPL source zones within the saturated zone.

Two goals of any DNAPL source treatment technology are to 1) reduce the mass of contaminants within the source area and 2) prevent migration of contaminants above unacceptable levels. The enhanced ISB technology reduces source mass and controls flux through the enhanced dissolution and desorption of DNAPL constituents into the aqueous phase, and subsequent microbially mediated degradation processes. Although enhanced ISB of DNAPL source zones has been demonstrated in the field at a few chlorinated solvent sites, expectations for rapid depletion of the source zone must be realistic. This training and guidance provide detailed requirements necessary to support the realistic determination of goals for ISB of a DNAPL source zone.

An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice

Interstate Technology Regulatory Council Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. A sound LNAPL understanding is necessary to effectively characterize and assess LNAPL conditions and potential risks, as well as to evaluate potential remedial technologies or alternatives. Unfortunately, many environmental professionals have a faulty understanding of LNAPL conditions based on outdated paradigms.

The ITRC LNAPLs Team is providing Internet-based training to improve the general understanding of LNAPLs. Better understanding leads to better decision making. Additionally, this training provides a necessary technical foundation to foster effective use of the forthcoming ITRC LNAPLs Team Technical Regulatory Guidance Document: Evaluating LNAPL Remedial Technologies for Achieving Project Goals (to be published in 2009).

This training course is relevant for new and veteran regulators, environmental consultants, and technically-inclined site owners and public stakeholders. The training course is divided into two parts:
  • Part 1: An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice
  • Part 2: LNAPL Characterization and Recoverability - Improved Analysis
In Part 1 of the training course, instructors explain how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts.

  • Part 2: LNAPL Characterization and Recoverability - Improved Analysis
In Part 2 of the training course, instructors address LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability.
The Training Exchange (Trainex)

The Training Exchange website (Trainex) is designed to provide a wide range of training information to EPA, other federal agency, state, tribal, and local staff involved in hazardous waste management and remediation. Trainex focuses on free training directed to federal and state staff. This site includes training schedules for deliveries of many courses, both classroom and Internet-based.

EPA works in partnership with organizations, such as the Interstate Technology Regulatory Council (ITRC), and other agencies, such as the Agency for Toxic Substances and Disease Registry (ATSDR), to offer training relevant to hazardous waste remediation, site characterization, risk assessment, emergency response, site/incident management, counter-terrorism, and the community's role in site management and cleanup.
