Communities across the United States are enduring, often unexpectedly, the effects of extreme events, such as excessive heat, prolonged droughts, extreme floods, and wildfires. In places where contaminated sites and waste management facilities are also present, communities must c...

The Handbook provides a conceptual framework and indicators to assess the indirect impacts of extreme events (e.g., extreme heat, floods, drought, wildfires) on communities through potential exposure to contaminant releases from nearby contaminated sites and waste management faci...

EPA will continue to improve and demonstrate its capability to assess environmental conditions and determine the relative risks that contaminated land poses to health and the environment. The Agency will ensure that the environmental data it collects is of known, documented, and ...

Due to sea level rise, salt marshes are projected to “migrate” landward as saltwater drowns existing marsh and creates new potential marsh conditions in what is currently non-marsh condition. The fate of marsh migration will be decided by the communities surrounding t...

When extreme events (extreme heat, floods, droughts, wildfires) happen, hazardous materials or contaminants may be accidentally released from sites and waste facilities creating further hazards for surrounding communities. Understanding community vulnerabilities underlies prepare...

The problem of contamination to land and groundwater from improper handling of hazardous materials/waste is faced by all countries. Also the need for reliable, cost-effective technologies to address this problem at contaminated sites exists throughout the world. ny countries have...

This report summarizes a variety of significant projects that the ETSC, located in the Land Remediation and Pollution Control Division (LRPCD), National Risk Management Research Laboratory (NRMRL), has supported throughout fiscal year 2013. Projects have addressed an array of env...

The United States Environmental Protection Agency (EPA or Agency) Office of Research and Development (ORD) created the Engineering Technical Support Center (ETSC) in 1987, one of several technical support centers created as part of the Technical Support Project (TSP). ETSC provid...

This report highlights significant projects that the ETSC supported in fiscal year 2016. These projects have addressed an array of environmental scenarios, including, but not limited to remote mining contamination, expansive landfill waste, cumulative impacts from multiple contam...

The risk of photo-activated PAH toxicity in contaminated aquatic systems has not been well characterized. To better indicate this potential, amphipods (Gammarus spp.) were collected from two PAH contaminated sites (Hog Island and USX), as well as a reference site (Chipmunk Cove)...

Remediation of sediments and groundwater contaminated with hydrophobic organic chemicals such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons remains a scientific and technical challenge. In order to overcome the short-comings of remediation strategies f...

Science provides the foundation for credible decision making. Science is observation followed by an interpretation and understanding of the result of the measurement. Observations may not be correct, complete, or fully descriptive of the phenomena. Interpretation based on avai...

This lecture will cover recent success in controlling and assessing the treatment of shallow ground water plumes of chlorinated solvents, other halogenated organic compounds, and methyl tert-butyl ether (MTBE).

A plethora of information is available when considering decision support systems for risk-based management of contaminated land. Broad issues of what is contaminated land, what is a brownfield, and what is remediation are discussed in EU countries and the U.S. Making decisions ...

In 2000, the United States Environmental Protection Agency (EPA) and the German Federal Ministry of Education and Research (BMBF) continued an ongoing partnership to gain an understanding of each country's approach to the cleanup of chemical contamination in order to protect huma...

Since 1990, the United States and Germany have worked bilaterally to identify, understand, and apply innovative technologies and policies for remediation and sustainable revitalization of contaminated sites in each country. Over a period of 15 years (= three Phases) remarkable b...

This report focuses on the problem of diving plumes, a term which generally refers to plumes that go deeper into aquifers with distances from their sources. This document presents the mathematical basis of software for real-time development and refinement of site conceptual model...

The term bioavailability has many different meanings across various disciplines of toxicology and pharmacology. Often bioavailability is concerned with human health aspects such as in the case of lead (Pb) ingestion by children. However, some of the most contaminated sites are ...

Communities across the world are experiencing a myriad of impacts from intensifying extreme heat, flood, drought, and wildfire events due to climate change. Further impacts can be experienced due to nearby contaminated sites and waste management facilities that are either activel...

Contaminated sediments are of interest to a broad group of programs in the agency. OERR and the Regions are interested in monitoring contaminated sediments to characterize/assess existing conditions, determine remediation alternatives, track spatial and temporal changes, and dete...

The attached presentation discusses the fundamentals of bioremediation in the subsurface. The basics of aerobic, cometabolic, and anaerobic bioremediation are presented. Case studies from the Delaware Sand & Gravel Superfund Site, Dover Cometabolic Research Project and the SABR...
