| EPA's Land Revitalization Team works across EPA Regions and program offices, and in partnership with other federal agencies and the private sector to support communities in their efforts to implement sustainable redevelopment strategies. This fact sheet highlights some of the tools that have resulted from the regional community-based projects undertaken with assistance from the Land Revitalization Program. These useful tools can be adapted for use in other communities. |

| Leak Detection for Landfill Liners: Overview of Tools for Vadose Zone Monitoring. This report was prepared under grant for EPA by Karen Hix, a National Network of Environmental Management Studies (NNEMS) fellow. It is intended to provide a basic summary and current status on several innovative types of leak detection tools that can be installed, in addition to monitoring wells, for identifying leaks in landfill liners. The document is not intended to be an inclusive report; it merely provides an overview of the existing work on leak detection technologies. The information was gathered by the author from a range of available sources, including project documents, reports, periodicals, Internet searches, and personal communication with involved parties. |

| Brookhaven National Laboratory (BNL) is a multi-discipline Department of Energy (DOE) research institute that has been in operation since 1947. Historical operations included running accelerators, nuclear research reactors, and other large complex equipment. Some of these operations caused groundwater contamination. This report discusses the tritium plume from the High Flux Beam Reactor and several strontium plumes from past operations at the Brookhaven Graphite Research Reactor, their discovery through monitoring, and their treatment. The tritium plume discovery led to public outrage; characterization, design, and implementation of a treatment system within 60 days; and eventual dismissal of Associated Universities Incorporated from the management of BNL despite the small health risk to employees or the public. Management of the strontium plume included a major alteration to the original regulatory cleanup agreement when field data showed the preferred alternative to be economically impractical. The report documents activities used to manage these contamination issues through source control, monitoring, modeling, plume and risk management, and communications. The lessons learned from these cleanup projects have altered the stewardship culture and methods of performing research, communicating with the public, and conducting work at BNL. These valuable lessons are highlighted in this report. |

| This report contains a review of the long-term groundwater monitoring network for the Permeable Reactive Barrier (PRB) and Soil Remedy Areas at the Clare Water Supply Superfund Site in Clare, Michigan. The current monitoring network in each area was evaluated using a formal qualitative approach and statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The report also contains recommendations for the groundwater monitoring networks based the results of these qualitative and quantitative evaluations. |

| This report contains a review of the long-term groundwater monitoring network for the StageRight (former Welltronics) Facility area near the Clare Public Water Supply, Clare Michigan. The current monitoring network was evaluated in September 2006 prior to activation of a new municipal well using a formal qualitative approach and statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). The goal of the groundwater monitoring program is to track changes in concentrations of priority chlorinated constituents that may affect the drinking water remediation system used to treat the public water supply. The report includes recommendations for groundwater sample frequency and location based on current hydrogeologic, pumping, and contaminant conditions. |

| This report contains a review of the groundwater monitoring network for Newmark Superfund Site in San Bernardino, California (Newmark Site). The Site consists of the Source, Newmark and Muscoy operable units (OUs). The current 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). Recommendations are made for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring goals for the system. The report evaluates the monitoring system using analytical and hydrogeologic data from sampling events conducted between May 1987 and January 2007. |

| This report reviews and provides recommendations for improving the groundwater monitoring network for Taylor Road Landfill Superfund Site in Seffner, Hillsborough County, Florida (Taylor Road Site). The current groundwater monitoring network has been evaluated using a formal qualitative approach as well as using statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). Recommendations are made for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring (LTM) goals for the system. The recommendations presented below are based on a technical review; balancing both the statistical results with goals of the monitoring system and site management decisions. The recommendations may not reflect the current regulatory requirements. The following report evaluates the monitoring system using analytical and hydrogeologic data from sampling events conducted between January 1995 and April 2007. |

| This report presents a description and evaluation of the groundwater and surface water monitoring program associated with the Bunker Hill Mining and Metallurgical Complex Superfund Site (Bunker Hill) Operable Unit (OU) 2. A monitoring network consisting of 77 groundwater monitoring wells and 18 surface water stations was evaluated to assess its overall effectiveness at achieving the OU2-specific monitoring objectives, and to (1) identify potential opportunities to streamline monitoring activities while still maintaining an effective monitoring program, and (2) identify data gaps that may require the addition of additional monitoring points. |
