An Inventory of Sources and Environmental Releases of Dioxin-Like Compounds in the United States for the Years 1987, 1995, and 2000 (EPA/600/P-03/002F, November 2006), is a peer reviewed report representing EPA’s assessment of dioxin sources and their emissions to the environment...

Atmospheric water generators (AWGs) have the potential to expand the availability of water during shortages, contamination events and interruptions of service. Given the nature of atmospheric water generation (i.e., condensation of atmospheric water vapor), high quality produced ...

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...

Following the collapse of the World Trade Center towers on September 11, 2001, New York State and Federal agencies initiated numerous air monitoring activities to better understand the ongoing impact of emissions from the disaster. This report focuses on these air measurement da...

This paper addresses United States Environmental Protection Agency (EPA) operational and research challenges for the next decade in the utilization of space-based observations for the assessment of terrestrial properties affecting land, water, and air resources, and human health....

New technologies that utilize capillary-based immunoassays promise faster and more quantitative protein assessment compared to traditional immunoassays. However, similar to other antibody-based protein assays, optimization of capillary-based immunoassay parameters, such as protei...

Recently, the rapid growth of miniaturized, lower-cost air sensors is changing the landscape of air pollution monitoring to enable cities, civil society, businesses, and consumers to monitor local air quality conditions, though with accuracy not on par with reference techniques. ...

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...

Report—Exposure estimates were performed to rank the various livestock carcass management options relative to one another for a hypothetical site and mortality scenario from a potential biological incident. Assessment included an ordinal scale ranking (ranking of individual condi...

Near-coastal (0-200 depth) ecosystems and species are under threat from increasing temperatures, ocean acidification, and sea level rise. However, species vary in their vulnerability to specific climatic changes and climate impacts will vary geographically. For management to resp...

EPA’s Office of Pollution Prevention and Toxics (OPPT) has developed a set of ten indoor exposure testing protocols intended to provide information on the purpose of the testing, general description of the sampling and analytical procedures, and references for tests that will be ...

The World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) Programme coordinates high-quality observations of atmospheric composition from global to local scales with the aim to drive high-quality and high-impact science while co-producing a new generation of pro...

The Region 3 “Making a Visible Difference in Communities” (MVD) initiative for Southeast Newport News, VA has taken a community-centric, place-based approach to identifying and delivering service to the area’s residents and the city as a whole. Beginning with a CARE (Community Ac...

In 1998, the U.S. Environmental Protection Agency (U.S. EPA) established the National Dioxin Air Monitoring Network (NDAMN) to help characterize the ubiquitous presence of dioxins in the environment. This final report represents the 2013 update to NDAMN.

To fulfill its mission to protect human health and the environment, EPA has established National Ambient Air Quality Standards (NAAQS) on six selected air pollutants known as criteria pollutants: ozone (O3); carbon monoxide (CO); lead (Pb); nitrogen dioxide (NO2); sulfur dioxide ...

EPA has released the document, <em>Procedures for Delineating and Characterizing Watersheds for Stream and River Monitoring Programs</em> (EPA/600/R-17/448F). This manual describes how states and tribes can delineate and characterize watersheds. It explains how to delineate water...

The emergence of small, portable, low-cost air sensors has encouraged a shift from traditional monitoring approaches for air quality. The U.S. Environmental Protection Agency (U.S. EPA), in collaboration with the South Coast Air Quality Management District’s (SCAQMD) Air Quality ...

The U.S. Environmental Protection Agency (EPA) is conducting a review of the air quality criteria and the primary (health-based) national ambient air quality standards (NAAQS) for sulfur oxides (SOx). The major phases of the process for reviewing NAAQS include the following: (1) ...

The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues. EIPs are designed to help remedial ...

A request for technical collaboration between the UNEP and the US EPA resulted in the establishment of a MCRADA. The purpose of this agreement was to evaluate an air quality monitoring system (referred to as the UNEP pod) developed by the UNEP for use in environmental situations ...

EPA announced the availability of the final report, <i>An Exploratory Study: Assessment of Modeled Dioxin Exposure in Ceramic Art Studios</i>. This report investigates the potential dioxin exposure to artists/hobbyists who use ball clay to make pottery and related products. Derm...

EPA announced the availability of the final report, <i>Metabolically Derived Human Ventilation Rates: A Revised Approach Based Upon Oxygen Consumption Rates</i>. This report provides a revised approach for calculating an individual's ventilation rate directly from their oxygen c...

For EPA, this Summer 2014, Denver CO, DISCOVER-AQ field research activity focused on assessing Federal Reference Methods (FRMs) and Federal Equivalent Methods (FEMs) for ozone (O3) and Nitrogen Dioxide (NO2), while comparing their operational performance to each other and to smal...
