Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s in a wide array of consumer products. PFAS are persistent in the environment and bioaccumulate. Thermal treatment methods are currently applied to a variety of mater...

The U.S. EPA’s Homeland Security Research Program (HSRP) is charged with protecting human health and the environment from accidental and intentional releases of toxic chemicals and other threat agents. Such chemical agents include Fourth Generation Agents (FGAs), which repr...

The Pawcatuck River flows through Westerly, Rhode Island before discharging into Little Narragansett Bay. The Pawcatuck River has a long history of pollution associated with textile and dye manufacturing due to historic mill operations along the riverbank. Operations at the Bradf...

Traditionally, risk assessment for environmental chemicals is based upon epidemiological and/or animal toxicity data. Since the release of the National Academy of Sciences Toxicity in the 21st Century: A Vision and a Strategy (2007) and Science and Decisions: Advancing Risk Asses...

These workshops will be platform to present recent research at EPA as it relates to best practices in site characterization, sample analysis, and suitable treatment technologies for mining, persistent organic pollutants, and microplastics. The first presentation will be expanding...

Tetragnathid spiders have been used as sentinels to study the biotransport of contaminants between aquatic and terrestrial environments because a significant proportion of their diet consists of adult aquatic insects. A key knowledge gap in assessing tetragnathid spiders as senti...

The comprehensive characterization of per- and polyfluoroalkyl substances (PFASs) is necessary for the effective assessment and management of risk at contaminated sites. While current analytical methods are capable of quantitatively measuring a number of specific PFASs, they do n...

Lead (Pb) and arsenic (As) contamination of soils is widespread in the United States and is an important source of exposure in young children. Early life exposure to metal(loid) contaminants has serious and long-lasting effects on health, making mitigation a critical public healt...

Lead (Pb) is a pervasive environmental contaminant commonly sourced from anthropogenic activities such as smelting, lead-based paint, and exhausted leaded gasoline.  Soils in residential neighborhoods are of particular concern as soil Pb may cause significant adverse health ...

Underground Storage Tanks and EJ Presentation for Region 2 and Community Engaged Research Collaborative for Learning and Excellence.  Community level model to assess cumulative impacts and effectiveness of multi-media interventions in improving public health and mitigating the e...

At least four polyfluorinated organic substances (i.e., 4:2-, 6:2-, 8:2- and 10:2- fluorotelomer alcohols; FTOHs) have sufficient vapor pressure (VP) to be designated as vapor-forming chemicals. Based on current guidance, vapor-forming chemicals warrant investigation for vapor in...

The dynamics of any given environmental decision-making context are complicated, including how to consider social-ecological systems connections. Decision support tools designed with a user in mind make it simpler and more natural to integrate science into the decision-making pro...

Illicit fentanyl activities can lead to complex contamination incidents and create exposure risks to law enforcement, emergency responders, remediation contractors, and the public. The objective of this presentation is to provide an overview of conducted research to assist i...

This sub-product will produce outreach materials such as presentations, peer-reviewed journal articles or EPA reports to disseminate results from the testing and evaluations conducted in the primary research area product SHC.402.6.5. To align with these activities, the proposed a...

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...

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...

As salt marshes attempt to migrate upland due to sea level rise, they will encounter many kinds of land development and infrastructure in highly populated, urbanized coastal communities. Hazardous and contaminated sites (HCSs) -- facilities and infrastructure that store...

Building community resilience requires centering equity in resilience planning processes. Tools and resources for strengthening community resilience need to address equity in both their content and the process for using them. This is especially so for communities living in proxim...

Soil avoidance tests have been developed for earthworms, Collembola, and other soil organisms. Many organisms are sensitive to toxic contaminants and have the ability to avoid areas of contamination.  Correlations between avoidance behavior and acute and other toxicities hav...

Lead (Pb) acontamination of soils is widespread in the United States and is an important source of exposure in young children. Early life exposure to metal(loid) contaminants has serious and long-lasting effects on health, making mitigation a critical public health goal. Removal/...

Soils are common sources of metal(loid) contaminant exposure globally. Lead (Pb) and arsenic (As) are of paramount concern due to detrimental neurological and carcinogenic health effects, respectively. Pb and/or As contaminated soils require remediation, typically leading to exca...

The open literature was searched for laboratory toxicity data for marine/estuarine organisms exposed to dichlorodiphenyltrichloroethane (DDT) and its degradation products of dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), dichlorodiphenylchloroethyle...

Persistent organic pollutants (POPs) such as Polychlorinated biphenyls (PCBs) are notorious for their widespread prevalence in aquatic and sedimentary ecosystems, recalcitrance, and carcinogenicity. Dredging and land-filling are still commonly used for treating PCB contaminated m...

Hester-Dendy (HD) multi-plate samplers have been widely used by state and federal government agencies for bioassessment of water quality through use of macroinvertebrate community data. To help guide remediation and restoration efforts at the Niagara River Great Lakes Area of Con...

Biochars with high phosphate (P) contents are promising amendments to remediate metal-contaminated soils due to their ability to form stable metal-P precipitates. However, their performance is usually assessed at a single pH. This study investigated the sorption of Pb, Cu, Zn, Cd...
