This presentation will cover recent research on nutrient inputs, agricultural management and nitrate concentrations in soil solution and groundwater in the southern Willamette Basin’s Groundwater Management Area (GWMA). Non-point sources are the predominant inputs of n...

A substantial fraction of nitrogen (N) fertilizer applied in agricultural systems is notincorporated into crops and moves below the rooting zone as nitrate (NO3−). Under-standing mechanisms for soil N retention below the rooting zone and leaching togroundwater is essential ...

Conventional mining-influenced water (MIW) treatment technologies are expensive to operate and maintain, require frequent labor, materials input, and sampling, and produce large quantities of treatment-generated solids that must be managed. In 2019, EPA’s Office of Superfun...

As climate change progresses in the Great Lakes, the region is increasingly vulnerable to invasion by mosquito species and increased viral transmission. Restoration activities that address degradation of benthos, degraded fish and wildlife populations, loss of fish and wildlife ...

Along urban streams and rivers, various processes, including road salt application, sewage leaks, and weathering of the built environment, contribute to novel chemical cocktails made up of metals, salts, nutrients, and organic matter. Due to heterogeneous land use and a myriad of...

The Society of Environmental Toxicology and Chemistry (SETAC) convened a Pellston workshop in 2022 to examine how information on climate change could be better incorporated into the ecological risk assessment (ERA) process for chemicals as well as other environmental stressors. A...

“Ecosystem services” are the benefits ecosystems provide to people. These benefits include providing food, clean air, clean water, recreation, and many other services that provide explicit or intrinsic values to people and communities. Investments in Chesapeake Bay re...

Presentation will be delivered at EPA webinar (Innovations in Environmental Science) and at ACS Fall Meeting. Overview of ongoing F3 research. Investigating the impacts of novel PFAS-free AFFF on environmental and human health is necessary to ensure they are safer, sustainable, a...

This presentation was previously cleared and presented to ECOS and ASTHO. Overview on planned experiments on assessment of PFAS alternatives.  Overview of ongoing F3 research. Investigating the impacts of novel PFAS-free AFFF on environmental and human health is necessary to...

This is the presentation based on the abstract, ORD.0.0.0.382.   What does it take for a good scientific idea to survive the political lawmaking process? How can scientists and engineers contribute to this effort from inside the legislative branch? For the year 2022, th...

Edge-of-field management practices designed to reduce nutrient pollution in waterways may support or alter critical habitat and ecosystem services in and around agricultural systems. Information on both target and non-target effects is needed to support management decisions as la...

Following Executive Order 14072 issued in April 2022, the Office of Science and Technology Policy, Office of Management and Budget, and Department of Commerce published the final National Strategy to Develop Statistics for Environmental-Economic Decisions (National Strategy) in J...

This presentation will examine how serious games are being used to enhance the US Environmental Protection Agency’s (US EPA’s) emergency response mission, by improving the ability of the emergency response community to quickly and effectively respond to a range of env...

Should biosolids be contaminated with an intentional malicious release or natural outbreak of Bacillus anthracis spores, a water resource recovery facility (WRRF) may need to consider if their treatment processes can sufficiently inactivate this pathogen. Three methods commonly e...

Source control of mine drainage and leachate from mining wastes is ideal, but there is limited use of control methods aside from removal of wastes to repositories or capping wastes in situ. In some locations, neither removal nor capping is possible; thus, there is renewed interes...

Disaster debris removal is essential for community recovery and resilience. However, it is a lengthy, costly, and logistically challenging part of response and recovery operations. Managing waste in a disaster situation requires the coordination of multiple entities at ...

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.

For many coastal areas around the Puget Sound, the interplay between weather, surface water, soils, evapotranspiration and groundwater flows is critical to modeling stream flow and predicting quantity and timing of flows under climate change. In this presentation, we introduce an...

Human activity has significantly increased the deposition of nitrogen (N) on terrestrial ecosystems over pre-industrial levels leading to a multitude of effects including losses of biodiversity, changes in ecosystem functioning, and impacts on human well-being. It is challenging ...

Background: Co-exposure to air pollution and neighborhood disadvantage may influence cognitive decline. We tested these associations in the context of dementia risk. Methods: We leveraged a cohort of community dwelling adults ≥65 years (n=5,112) enrolled from 2011 to 2018 in ...

Combustion of mixed materials during open air burning of refuse or structural fires in the wildland urban interface produces emissions that worsen air quality, contaminate rivers and streams, and cause poor health outcomes including developmental effects. The zebrafish, a freshwa...

In 2018, the U.S. Environmental Protection Agency (EPA) established the EPA Environmental and Human Health Indicators Community of Practice (EHHI CoP) with members from across the agency. The purpose of the community has been to advance environmental and human health indicator[1]...

We reviewed the available social-ecological, hydrological, and geochemical literature for the ecological systems of the San Juan Bay Estuary (SJBE), a site in the Environmental Protection Agency’s National Estuarine Program. The objective of the review is to gather in one place a...

Evaluating biomarkers of stress in amphibians is critical to conservation, yet current techniques are often destructive and/or time-consuming, which limits ease of use. In the present study, we validate the use of dermal swabs in spotted salamanders (Ambystoma maculatum) for bioc...

Ricin is a highly toxic protein, capable of inhibiting protein synthesis within cells, and is produced from the beans of the Ricinus communis (castor bean) plant. Numerous recent incidents involving ricin have occurred, many in the form of mailed letters resulting in both buildin...
