| During the late 1960s, a ravine in rural woodlands in Douglas County, GA, was used as an illegal dumping area for industrial solvents, paint removers, and other toxic wastes. Contamination at this site was so severe that excavation of the soil was not feasible because of the potential for dangerous levels of fugitive emissions. This video highlights the unique multiphase cleanup of the site, which involved erecting a prefab building over the contaminated area to control and treat toxic vapors released from the soil. Running time is 6 minutes. |

| The document provides guidance for designing and conducting soil remediation activities at RCRA and other hazardous waste sites so that cross-contamination is minimal. The document is expected to assist in reducing exposure of workers to contaminants by identifying the potential for transfer from medium to medium and recommending control mechanisms that could be applied during implementation of treatment technologies for soil. The BMPs are provided for seven technology categories: containment technologies; soil washing; thermal treatment; vapor extraction; bioremediation; incineration; and other physical and chemical treatments. The document also provides case studies and information about field validation activities that EPA undertook at soil remediation sites in 1996 and 1997. |

| EPA has issued three technical guides to assist environmental professionals in scoping, data management and strategic sampling activities at hazardous waste sites. EPA intends for the guides to strengthen Superfund site characterization activities to facilitate stronger site remedy decisions and improved remedy performance, among other objectives. This technical guide provides best practices for efficiently managing the large amount of data generated throughout the data life cycle. Thorough, up-front remedial investigation and feasibility study (RI/FS) planning and scoping combined with decision support tools and visualization can help reduce RI/FS cost and provide a more complete conceptual site model (CSM) earlier in the process. Two additional companion technical guides should be used in conjunction with this data management technical guide: Smart Scoping for Environmental Investigations and Strategic Sampling Approaches. |

| The purpose of this issue paper is to provide a practical guide on the application of the geologic principles of sequence stratigraphy and facies models to the characterization of stratigraphic heterogeneity at hazardous waste sites. Application of the principles and methods presented in this issue paper will improve Conceptual Site Models (CSM) and provide a basis for understanding stratigraphic flux and associated contaminant transport. This is fundamental to designing monitoring programs as well as selecting and implementing remedies at contaminated groundwater sites. EPA recommends re-evaluating the CSM while completing the site characterization and whenever new data are collected. Updating the CSM can be a critical component of a 5 year review or a remedy optimization effort. |

| The purpose of this issue paper is to recommend information to include in groundwater monitoring reports that will lead to improved report consistency and a useful, readable format. Incorporation of the recommended information will standardize groundwater monitoring report deliverables, which may in turn inform site characterization strategies, analysis of remedial alternatives, monitoring network optimization, remedy performance evaluation, continual refinement of the conceptual site model (CSM), and technical evaluation of groundwater data in five-year reviews. |

| This report is a collection of abstracts summarizing 37 case studies of site remediation projects prepared by Federal agencies. The case studies were undertaken to document the results and lessons learned from early technology applications. They will help establish benchmark data on cost and performance which should lead to greater confidence in the selection and use of cleanup technologies. The case studies were collected under the auspices of the Federal Remediation Technologies Roundtable as part of a larger effort to improve future project documentation and information transfer. |

| This ITRC web-based guidance document describes how biochemical reactors work, the contaminants treated, various designs, monitoring and maintenance requirements and schedules, and troubleshooting. Biochemical reactors are land-based engineered treatment systems that use an organic substrate to drive microbial and chemical reactions that reduce concentrations of metals, acidity, and sulfate in mining-influenced water. Fifteen case studies present real-world examples and include details such as volumes of water treated, substrates used, pH and metals concentrations, and biochemical reactor size. |

| The Escambia Wood Preserving Site located in Brookhaven, Mississippi, is a former wood preserving facility that used pentachlorophenol (PCP) and creosote to treat wooden poles. Located on the site are two pressure treatment cylinders, a wastewater treatment system, five bulk product storage tanks, seven condenser ponds (including a 3,000,000-gal., unlined primary surface impoundment), and excavated soil materials containing process chemicals from past spills. In April 1991, U.S. EPA Region 4 initiated a removal action to eliminate all sources of potential releases to the environment. |

| In 1988, the U.S. Air Force initiated a study at Hill Air Force Base (AFB) to examine the potential of bioventing to remediate JP-4 jet fuel-contaminated soils. Bioventing is the process of supplying oxygen in situ to oxygen-deprived soil microbes by forcing air through contaminated soil at low airflow rates. Because bioventing equipment is relatively noninvasive, this technology is especially valuable for treating contaminated soils at military bases, industrial complexes, and gas stations, where structures and utilities cannot be disturbed. Promising results from the Air Force’s initial study prompted the U.S. EPA National Risk Management Research Laboratory (NRMRL) and the Air Force to conduct a field evaluation of bioventing at Hill AFB and at Eielson AFB (see separate fact sheet, EPA/540/F-95/506B). The main objective of the Hill AFB evaluation was to determine the effect of air injection flow rate on the effectiveness of bioventing in stimulating biodegradation while minimizing volatilization. The evaluation also provided an opportunity to gain experience in bioventing large volumes of soil with plumes of fuel that extend deep beneath the surface as well as under roads, underground utilities, and buildings. |

| This Bioremediation Field Initiative project is under way in St. Louis Park, Minnesota, at the former site of Reilly Tar and Chemical Corporation’s coal tar distillation and wood preserving plant. From 1917 to 1972, wastewater discharges and dumping from this plant contaminated about 80 acres of soil and the underlying ground water with wood preserving wastes. In 1978, the Minnesota Department of Health discovered significant concentrations of polycyclic aromatic hydrocarbons (PAHs) in six municipal drinking water wells neighboring the Reilly Tar plant. St. Louis Park currently is pumping and treating thecontaminated ground water plume, but without an effort to control the source of PAHs, pumping and treating might be necessary for several hundred years. |

| This document was prepared by Erica Borum, a NNEMS grantee under a fellowship from the U.S. Environmental Protection Agency. The objective of this paper is to present in situ bioremediation in fractured bedrock as an innovative technology for the treatment of chlorinated solvents. The heterogeneity of fractured bedrock and the persistence of chlorinated aliphatic hydrocarbons (CAHs) create a costly, remedial challenge in the subsurface. Due to the existence of microorganisms in the subsurface, bioremediation processes in fractured bedrock have proven to be a potentially successful remedial process. This paper summarizes ten on-going case studies that are utilizing bioremediation of chlorinated solvent and will discuss the parameters of the projects as well as current findings. |
