| This article, published in the Spring 2003 Remediation journal through a collaboration between Marsh Insurance and the New Jersey Institute of Technology, describes a case example where the Triad approach managed residual uncertainty about the extent of contamination at a Brownfields redevelopment property. Triad improved confidence in the conceptual site model (CSM) so that uncertainty about the costs and effectiveness of remediation were greatly reduced. This in turn significantly lowered the cost of the cleanup cost cap insurance policy. |

| This document was prepared by Emily Keane, a National Network for Environmental Management Studies (NNEMS) grantee under a fellowship from the U.S. Environmental Protection Agency. The goal of this document is to provide information about the fate, transport, and toxicity associated with the use of nanoscale zero-valent iron (nZVI) for Superfund remediation. Specific and unique site conditions are likely to determine the usefulness and influence the fate and transport of nZVI particles during remediation efforts. Factors to consider prior to application include: effects of geochemistry on the mobility of nanoparticles, use of metal catalysts and coatings on the movement of nZVI particles and other variables affecting the fate and transport of nZVI in the environment. Other considerations include potential environmental and human health effects as a result of the fate and transport of nZVI in the environment. |

| This fact sheet, produced by the FRTR, summarizes activities of member agencies' remediation programs and describes recently published cost and performance case studies and reports. The 2010 fact sheet also highlights FRTR member agencies' Vapor Intrusion (VI) activities, which was the focus of the November 2009 FRTR meeting. A summary of that meeting and the presentations on Vapor Intrusion are posted on the FRTR website. In March 2010, FRTR launched the Vapor Intrusion Data Workgroup in partnership with several federal agencies. Recently, EPA Region 7 published a fact sheet, What you should know about Vapor Intrusion, to answer frequently asked questions about VI. |

| In cooperation with the EPA's 21M2 Initiative, the USGS has completed a study on the use of nylon-screen diffusion and pushpoint samplers for obtaining samples for metals analysis in sediment pore water. The study concluded that both samplers were effective in collecting pore water samples and yielded similar results. The study also indicated wide variability in metals concentrations over short distances within the sediments. |

| A five-year review documenting the progress of Applied Materials Building 1 (AM1) toward remedial goals was completed in 2010. The site has largely achieved remedial goals for groundwater; however, specific National Priorities List (NPL) close-out prospects for sites with rare or intermittent exceedances of groundwater cleanup goals over a limited spatial extent are not clear. Additionally, the presence of groundwater plumes on adjacent properties may complicate the close-out decision. This memorandum reviews historical site data and how they might support the development of a long-term, close-out strategy for the AM1 site. Statistical analyses were performed using modules within the Monitoring and Remediation Optimization System software (MAROS) and ProUCL software. |

| The Celanese site is located in Shelby, North Carolina. Operation of the P&T system was discontinued on a trial basis for two years to evaluate monitored natural attenuation as a potential ground water remedy. The system has not been restarted. EPA Region 4 is requesting a third-party review to help determine if the system should be restarted, if a modified system should be restarted, or if another type of ground water remedial approach is warranted. This report provides a brief background on the site, a summary of observations made from the document review, and recommendations regarding future modifications to the existing remediation system (including associated investigation activities). The cost impacts of the recommendations are also discussed. |

| This report describes a pilot study for a Region-based optimization program, implemented by a Regional Optimization Evaluation Team (ROET) that was conducted in U.S. EPA Region III at Fund-lead sites with pump-and-treat (P&T) systems. The ROET is comprised of Regional management, Regional technical staff, technical experts unassociated with the sites, and a representative from EPA's Office of Superfund Remediation and Technology Innovation (OSRTI), and the pilot program represents a modification of the process currently used in the nationwide OSRTI program. The report provides a discussion of how the pilot program differs from current practice and lessons learned in the pilot study. |

| This report reviews and provides recommendations for a long-term groundwater monitoring network for the Gilson Road (Sylvester) Superfund Site (Gilson Road). Extensive remedial actions have been successfully implemented at the site over the past 30 years, and the site is currently in a long-term operation and maintenance phase (O&M). The primary goal of developing an optimized groundwater monitoring strategy at the Gilson Road site is to create a dataset that fully supports site management decisions while minimizing expense and effort associated with long-term O&M. |

| This report reviews and provides recommendations for a long-term groundwater monitoring network for the Kearsarge Metallurgical Corporation Superfund site (KMC site). The KMC site is a former foundry and metal fabrication facility in Conway, New Hampshire, listed on the National Priorities List (NPL) in 1984. The site is currently in a long-term operation and maintenance (O&M) phase. The primary goal of developing an optimized groundwater monitoring strategy at the KMC site is to create a dataset that fully supports site management decisions relating to the long-term remedial strategy and reuse options for the property. In this report, the current KMC site groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The evaluation of the monitoring system included data collected both prior to and during active groundwater extraction (1983 - 2005) and after cessation of the extraction remedy (2006 - 2009). Network recommendations are made for groundwater sampling frequency and location based on lines of evidence developed from qualitative factors as well as statistical results. |

| The Somersworth Sanitary Landfill Site (Somersworth site) is a former landfill in southern New Hampshire that is on the National Priorities List (NPL). The landfill was closed in 1981 and has had a groundwater monitoring network since the 1980s. Groundwater remedies were installed by 2001, and the site is currently in the long-term monitoring phase of operation and maintenance (O&M). U.S. EPA Region 1 requested a review of the Somersworth site groundwater monitoring plan. Site monitoring data was reviewed and statistical and heuristic evaluations were performed using the Monitoring and Remediation Optimization System software (MAROS) in 2007. Inputs, results and recommendations for the groundwater monitoring network, including the results based on the MAROS analysis, were reviewed. |

| This brief document addresses 25 key questions, providing a concise overview of current knowledge regarding the management of subsurface chlorinated solvent releases. Source zone areas are defined and discussed, with summaries of the benefits and limitations of various source characterization and remediation technologies. The document addresses current technical and practical limitations, as well as the changes that have occurred over time at many chlorinated solvent sites. Although the document is meant neither to foster nor discourage source zone treatment, it takes a hard look at the costs and performance of the most commonly used source zone treatment technologies and compares source treatment to alternative containment approaches. |
