Remediation of environmental contamination at sediment sites is complex, expensive, and the clean-up procedures themselves can be an environmental stressor. Selecting a cleanup technique that balances long term effectiveness and minimal adverse environmental impacts is critical t...

The technology profile was developed to provide contaminated site staff with insights on the potential use of phytotechnologies at contaminated sites. 

Brownfield redevelopment offers opportunities for communities to revitalize spaces that might pose a public health risk. But there are growing concerns about redevelopment contributing to gentrification. To explore these concerns, a research team at the US Environmental Protectio...

Environmental surveillance data provide gold-standard information for informing regulatory decisions related to chemical pollution. However, these data are expensive and time consuming to generate. Strategies are needed for the selection of optimal sampling locations and measured...

Per- and polyfluoroalkyl substances (PFAS) are a serious human health risk, and fish are a significant dietary source of PFAS. An analysis of fish from Minnesota, a ceded territory, and reservation waters within the Lake Superior Basin was conducted to provide a better understand...

Lab and field studies indicate that per- and polyfluoroalkyl substances (PFAS), a group of highly persistent chemicals, impair avian reproduction. However, the molecular mechanisms and modes of action through which PFAS cause adverse apical outcomes in avian species have not been...

  Within the EPA PPRTV program, read-across is routinely used for screening-level human health assessment of data-poor chemicals found at contaminated sites across the U.S. Analogues are identified and evaluated based on a three major types of similarity (structure, tox...

Per- and polyfluoroalkyl substances (PFAS) are fluorinated, human-made chemicals found in fish in Rhode Island and throughout the country. Their effects are not well understood, but some PFAS are linked to adverse health impacts such as decreased fertility, increased cancer risk,...

This sub-product is a presentation on the progress of the EPA report on the impacts and costs associated with flooding at OLEM sites and facilities. This presentation presents the literature review, screening approach, and synthesis of focus group discussions with EPA headquarter...

Climate change impacts affecting underground storage tank systems. Climate change has the potential to significantly impact underground storage tanks. Flooding and wildfires can result in fuel releases from this infrastructure impacting drinking water resources and community hea...

Illicit fentanyl activities create exposure risks to law enforcement, first responders, and remediation contractors.  Remediation operations will benefit from improved knowledge on sampling for and in situ neutralization options of fentanyl and its analogs on ...

The cleanup of contaminated sites hinges upon relationship building and trust. EPA staff work alongside state, Tribal, territorial, and local responders, environmental and public health agencies. They undertake engagement with affected residents, officials, and businesses. Withou...

For contaminated sites, conceptual site models (CSMs) guide the assessment and management of risks, including remediation strategies. Recent research has expanded diagrammatic CSMs with structural causal modeling to develop what are nominally called conceptual Bayesian networks (...

Working with all the states, territories and tribes, UST Finder is being updated to reflect the latest data on the tanks infrastructure, fuels and potential receptors of concern. In addition to expanded data on the infrastructure,  it will include the latest data on extreme weath...

Back diffusion refers to the contamination of a high permeability layer or zone (HPZ) by the diffusive transport of contaminant out of an adjacent low permeability layer or zone (LPZ).  It may become a significant factor at older sites once the primary contaminant source is ...

Metal concentrations in urban soil samples frequently contain levels that are not attributable to a specific site. These concentrations are from diffuse sources and distinguishing them from site contaminants can better inform remediation decisions. To understand urban background ...

The International Commission on Radiological Protection is an independent, international, non-governmental organization focusing on the protection of humans and the environment, which makes recommendations that inform policy, regulation, guidelines, and practice worldwide. They h...

Working with all the states, territories and tribes, UST Finder is being updated to reflect the latest data on the tanks infrastructure, fuels and potential receptors of concern. In addition to expanded data on the infrastructure, it will include the latest data on extreme weathe...

US EPA's Office of Research and Development (ORD) is sponsoring a presentation on electrokinetic (EK)-enhanced in situ remediation technologies that are available for addressing contaminants in low-permeability (low-k) subsurface environments where conventional hydraulic delivery...

The presentation to the EPA ORD-Region 9-States, Tribes, and Pacific Islands meeting will provide an overview of ORD’s Climate Change research.  It will highlight specific topics such as climate scenarios/extreme events, climate change and air quality, contaminated sit...

This presentation to the EPA ORD-Region 1-States meeting will provide an overview of ORD's climate research.  It will also provide updates and highlights of new regional datasets available and collaborative climate work in Region 1.

Per- and poly-fluorinated alkyl substances (PFAS) are a group of anthropogenic organic compounds that contain multiple CF2 groups. The chemistry of the compounds makes them extremely useful in a wide range of chemical applications, and they have found use in a numerous consumer a...

This sub-product is specifically for updating the existing DW TDB with the most recent publications containing PFAS treatment data relevant to drinking water.

Per- and polyfluoroalkyl substances (PFAS) are a human health risk, and fish are a dietary source of PFAS. An analysis of fish from Minnesota, a ceded territory, and reservation waters within the Lake Superior Basin was conducted to provide a better understanding of PFAS contamin...

A presentation on the utility of and an approach for incorporation of ecosystem service consideration into decision-making. The presentation focuses on two points: 1) Defining ecosystem services so as to be consistent, comprehensible, and more easily operationalized for decision-...
