Overview of the EPA ORD's extramural research grant programs such as STAR, P3, and National Priority will be presented to the academic researchers from Ohio State University.

Current methods for cancer risk assessment are resource-intensive and not practical for thousands of untested chemicals in the environment. In earlier studies, we developed a new approach methodology (NAM) to identify liver tumorigens using gene expression biomarkers and associat...

To continue estimating hedonic property models, possibly expanding environmental justice analyses, and undertaking other analyses that use property characteristics, EPA is interested in acquiring national property transaction data as a replacement for Zillow’s ZTRAX data. Z...

For decades, researchers have sought to document injustices, highlight activism, and identify pathways in moving toward environmental justice (EJ). EJ research regarding water has been predominantly focused on drinking water. This project sought to identify and analyze the breadt...

This is an invited outreach presentation to provide an introduction to environmental justice. It presents no new data or ongoing research from ORD.

Arsenic discharge and mobilization from the pollution source depend on the minerals that host arsenic, the matrix of local water, the redox condition, and the water flow. A disposable enzyme sensor has been developed for As(III) determination in site assessment. To evaluate the s...

This is the PowerPoint slide deck for the Science to Achieve Results (STAR) “Air Quality Information: Making Sense of Air Pollution Data to Inform Decisions in Underserved Communities Overburdened by Air Pollution” Funding Opportunity Informational Webinar that will b...

This is a talk I will give as part of the Toxics Webinar | Issue Cover Authors of 2023. I will only discuss published work that has been cleared and published in Toxics last year.

Climate change presents cascading and compounding threats to low-income and underrepresented communities, increasing the need for equitable resilience planning. However, many local governments face challenges incorporating community voices with resilience and vulnerability data i...

Increasing and inequitable impacts from climate change and other hazards are a growing concern for communities and a focus of planning efforts. This research, conducted through case studies with several U.S. communities, explores and develops ways to center equity in resilience p...

Members of the Puente Jobos community in Puerto Rico shared with EPA concerns they have about particulate matter in their community and whether the location of the regulatory air monitoring site represents the community's exposure. EPA developed a research study design that invol...

Members of the Puente Jobos community in Puerto Rico shared with EPA concerns they have about particulate matter in their community and whether the location of the regulatory air monitoring site represents the community's exposure. EPA developed a research study design ...

Background:  Restoration efforts have led to the return of anadromous fish, a potential source of food for the Penobscot Indian Nation, to the previously dammed Penobscot River, Maine.  Objective:  U.S. Environmental Protection Agency (EPA), in collaboration with t...

Impoverished and under-served communities are often exposed to the worst environmental and climate hazards. Identifying these communities and building their resilience capacity to withstand such hazards is a vital justice aspect of environmental management. Building community res...

Collocation of air quality sensors at existing regulatory air monitoring sites allows sensor data comparison against quality-assured reference data and is a cost-effective method for understanding the performance of lower-cost air sensors. In some cases, collocations can allow fo...

This is a two-page description of efforts undertaken from Oct 2022-Sept 2023 to scope HERA 401.3.3. It frames the issues we are addressing, the main research questions, activities of the core team and cross-EPA working group, challenges, and future activities.

Coastal areas are important places to live, work, play, and more. They are areas with high social and economic value, but also with considerable commercial and private uses which lead to conflicts, disproportionately affected communities, and complex environmental decision making...

This class lecture gives two examples of how stable isotopes can be used to better understand nutrient dynamics in coastal marine systems. I give examples from my dissertation research on Egypt's Nile Delta and from our ongoing work in the San Juan Bay Ecosystem in Puerto Rico.

In this study, proportional response addition (Prop-RA), a model for predicting response from chemical mixture exposure, is demonstrated and evaluated by statistically analyzing data on all possible binary combinations of the four regulated trihalomethanes (THMs). These THMs were...

Environmental justice seeks to affirm individual’s rights to a healthy environment within communities that are subjected to a disproportionate burden of environmental hazard. These communities often experience higher levels of chronic stress and reduced quality of life, whi...

EPA has developed a suite of targeted analytical methods for measurement of PFAS in waters, soils, sediments and biosolids for regulatory and research applications. Quantification at sub part per trillion levels is possible with capable instrumentation, by selection of an appropr...

Federal agencies are increasing efforts to provide support to local communities for climate adaptation and hazard resilience. This involves engaging communities using approaches to understand and address problems holistically, particularly where equity and environmental justice a...

As the risks of climate change impacts become more apparent and more severe, communities need ways to plan, adapt, and transform in order to increase resilience. Disasters cause widely disparate impacts on communities and populations with differential vulnerability, making necess...

Background:Atopic dermatitis (AD) is an inflammatory skin disease caused by allergen exposures and estimated to affect ∼20% of children. Children in urban areas have a higher prevalence of AD compared with those living outside of urban areas. AD is believed to lead to asthma ...

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...
