The primary objective of this pilot-scale project was to demonstrate and validate anaerobic membrane bioreactor (AnMBR) technology for domestic wastewater treatment. Specific objectives associated with this project included: 1) demonstrate the effectiveness of AnMBR at treating s...

This module promotes student discovery and learning about the interconnectedness of humans and ecosystems. Centered on ecosystem services, these six classroom-ready lessons incorporate use of EnviroAtlas to encourage a systems approach to thinking about the world. This approach p...

Active soil-gas sampling has been used as a reconnaissance method in support of soil and groundwater sampling of volatile and biodegradable organic compounds for over 30 years. More recently, soil gas sampling has been used directly to evaluate risk posed by vapor migration from ...

This report describes the state of the science with respect to total Nr deposition budgets in the United States and the research needed to improve these budgets from both a measurement and modeling perspective. The document is intended to serve as a roadmap for research activiti...

The EPA Office of Research and Development's Site Characterization and Monitoring Technical Support Center (SCMTSC) provides contaminated sites program staff with the most up-to-date science and information to help solve complex issues at their sites. SCMTSC offers a suite of tec...

For the past several years, Metropolitan Sewer District of Greater Cincinnati (MSD) and USEPA has been investigating the use of peracetic acid (PAA) as an alternative to chlorination and several aspects of its implementation in the real world. We have studied the treatment of sec...

International concern about contaminated sediments is increasing as sustainable practices are needed to maintain water resources and waterways as important economic, commercial, recreational, and community resources. Sediments often serve as long-term sinks for legacy pollutants,...

The information in this document is from a collaborative effort between the U.S. EPA, Region 6 Superfund Division and the Office of Research and Development, National Risk Management Research Laboratory. Research was conducted at the US EPA Region 6 Addison Texas Facility. The fi...

This report explores rainfall-runoff models, their generation methods, and the categories under which they fall. Runoff plays an important role in the hydrological cycle by returning excess precipitation to the oceans and controlling how much water flows into stream systems. Mode...

As part of EPA/ORD's Homeland Security research program, there is a need to improve strategies for emergency response following a wide-area release of a biological agent. Modeling tools that simulate the dispersion of biological agents for a wide-area release may be used to prio...

The United States Environmental Protection Agency's (EPA) Water Modeling Workgroup (WMW) provides support for core surface water quality modeling tools used in Clean Water Act programs. The WMW identified a set of 18 separate surface water modeling applications that are currently...

The report is intended to be applicable to consequence management activities that EPA will be involved with and will require waste characterization. This best practices document is intended to be general and all-hazards in nature, applicable to a multitude of settings, and to pro...

BASS (Bioaccumulation and Aquatic System Simulator) is a Fortran 95 simulation program that predicts growth, population, and bioaccumulation dynamics of age-structured fish assemblages exposed to hydrophobic organic pollutants and class B or borderline metals that complex with su...

This report updates the findings of the first Report to Congress, published in 2011, with respect to environmental and resource conservation impacts, which together are intended to address the Section 204 statutory impacts since the passage of the EISA. This report reflects the c...

This report discusses results from a bench scale study that investigated the impact of dirt and grime on pH amended bleach and diluted bleach decontamination efficacy as commonly encountered on relevant subway rolling stock and subway infrastructure surface materials, including t...

Unconventional diluted bitumen (dilbit) oil products present an increasing environmental concern because of extensive transport in North America, recent spills into aquatic habitats, and limited understanding of environmental fate and toxicity. Dilbits are blends of highly weathe...

This report provides an assessment of the current coverage of community environmental management needs for decision making by existing software tools. The gap analysis provides an assessment of 1) what software tools EPA has either developed or catalogued from others, 2) how thos...

Cost effective and reliable techniques are needed for the characterization of contaminated fractured rock aquifers. Two important characteristics of contaminant transport are groundwater velocity (or flux) and contaminant mass flux. Conventional methods for characterization in ...

The timely distribution of satellite derived data is necessary for adaptive water quality management decision making. Prompt dissemination of remotely sensed water quality data enables public warnings within days and the ability to issue seasonal assessments in the same calendar ...

This report summarizes the results of biological decontamination experiments performed at the WSTB focused on removing Bacillus globigii spores adhered to the inner surface of the 8-inch water pipe. B. globigii spores are a non-pathogenic surrogate for B. anthracis, which is the...

Report on the decontamination efficacy of low levels of hydrogen peroxide vapor (HPV) was evaluated on common building materials (glass, bare pine wood, carpet, painted wallboard paper, unpainted concrete, and ceiling tile) contaminated with Ba spores.

The objective of this research was to measure methane potential (Lo) in commercial and residential waste samples obtained from waste collection vehicles at the point of disposal. Previously reported Lo values span a wide range including estimates substantially lower than the cur...

A large-scale outdoor biological disaster requires a better understanding of how rainfall and water-based decontamination measures would transport contaminants. Over the last few years, the United States Environmental Protection Agency’s (EPA’s) Homeland Security Research Program...

The general goal of the work described here is to build a knowledge base of tools and models addressing human health assessment that are appropriate for situation-specific and near-field exposure scenarios that may be encountered as part of a chemical life cycle. More specificall...
