Extensive research in recent years has reported higher per- and polyfluoroalkyl substance (PFAS) concentrations in municipal solid waste (MSW) landfill leachate than other municipal wastewaters, including multiple studies of leachate from MSW landfills in the United States. Becau...

Climate change could add a variety of uncertainties to hydrological processes and water resources. Very limited efforts have been devoted to applying the US-EPA (Environmental Protection Agency)’s Hydrologic and Water Quality System (HAWQS) model for predicting climate chan...

Air pollution monitoring using mobile ground-based measurement platforms can provide high-quality spatiotemporal air pollution information. As mobile air quality monitoring campaigns extend to entire fleets of vehicles and integrate smaller-scale air quality sensors, it is import...

To address our climate emergency, “we must rapidly, radically reshape society”—Johnson & Wilkinson, All We Can Save. In science, reshaping requires formidable technical (cloud, coding, reproducibility) and cultural shifts (mindsets, hybrid collaboration, inc...

Current solar panels have an average lifespan of about 25 years. Millions of solar panels installed from the early 2000s are approaching the anticipated end-of-life. There is limited interest in panel recycling, reflecting the relative value of recovered materials, primarily sili...

This is a 10-minute slide set about the tool "GIWiz" for the Oct 26, 2016 SSWR webinar presentation on the "Green Infrastructure Toolkit". GIWiz is an interactive web application that connects communities to EPA Green Infrastructure tools & resources. GIWi...

Data visualization tools that are quick and easy to use, require no coding skills, and can be used with any type of sensor are in high demand. In addition to visualizing their own data, users often wish to compare the data they collect with other data sources such as nearby instr...

Relationships between toxicity and chemical hydrophobicity have been known for nearly 100 years in mammals and fish, typically using the log of the octanol:water partition coefficient (Kow). The current study reassessed the influence of mode of action (MOA) on acute aquatic ...

Exposure to environmental pollutants or xenobiotics is often toxic to fish, reducing their ability to develop, grow, reproduce, or survive. While variation among fish species in their sensitivities to pollutant classes sometimes reflects inherent differences in biological targets...

Hypoxia, or low dissolved oxygen (DO) is a common outcome of excess nitrogen and phosphorus delivered to coastal waterbodies. Shallow and highly productive estuaries are particularly susceptible to diel-cycling hypoxia, which can exhibit DO excursions between anoxia (DO ≤1&nbs...

The Clean Air Act requires the Environmental Protection Agency to set National Ambient Air Quality Standard (NAAQS) to protect the public health and welfare against exposures to the “criteria” air pollutants. EPA has identified six criteria pollutants, including ozone...

The increasing environmental and human health concerns about lead in the environment have stimulated scientists to search for microbial processes as innovative bioremediation strategies for a suite of different contaminated media. In this paper, we provide a compressive synthesis...

Before the era of fossil fuel use, water provided power for industrial processes in the USA through a ubiquitous network of dams and mills. This infrastructure was constructed concurrently with widespread deforestation and sedimentation during the 18th through 20th centuries caus...

Rationale In stable isotope mass spectrometry, isotope delta values are normalized to internationally recognized reference scales using a combination of certified and in-house isotope reference materials. Numerous techniques exist for performing this normalization, but these meth...

Mining influenced water (MIW) emitted from mine sites poses a major environmental concern due to its impact on water contamination. This is caused by low pH and the presence of high concentrations of toxic metals in soluble and bioavailable forms. Biological activity creates redu...

Time is an important, but underappreciated component in chemical safety decisions. An estimated 15% of the chemicals in domestic commerce have traditional repeated dose toxicity testing data and even fewer have human health assessments that can be used to inform regulatory action...

•       An updated version (2) of EPA’s River Basin Export Reduction Optimization Support Tool (RBEROST) has been developed to provide nutrient management strategies for the Puget Sound Basin.  RBEROST is an R-based tool that sets up ...

The usage of multi-walled carbon nanotubes (MWCNTs) has increased exponentially in the past years, but, potential toxicity mechanisms are not clear. We studied the transcriptomic alterations induced by one multiwalled carbon nanotube (MWCNT) and its –OH and –COOH func...

Presentation to disseminate information about ongoing and past research investigating methods to value ecosystem services associated with coastal ecosystems for a fuller accounting of costs and benefits in decisions. 

Poster describing research results of geospatial analysis to assess overlap between offshore wind energy development and commercial fisheries and to examine economically relevant tradeoffs between these two uses. Poster presented at the Natural Capital Symposium at Stanford Unive...

Presentation at the MPS World Summit conference 2024, Track 2.7: Modeling diversity and population health with MPS. 

The developing brain is particularly vulnerable to neurotoxicity, and exposures to environmental neurotoxicants during this period can result in altered brain development. To investigate the effects of chemical exposures on neurodevelopment, human induced-pluripotent stem cell (i...

A goal of coral reef management is to provide habitat and nursery areas for fish populations. This requires simple and reliable methods for characterizing biological and physical reef features that contribute to fish habitat. Most attempts to establish this relationship have been...

Ball milling was used to fabricate a nanocomposite of 20% hickory-biochar (600°C) and 80% expanded vermiculite (20%-BC/VE). This novel adsorbent had much higher removal of As(V) from aqueous solution than ball-milled biochar and expanded vermiculite. Characterization of these...

An objective of federal, state, and local environmental management programs is to provide citizens with clean waters and the benefits associated with them. Communicating the importance of clean water to the public is often thought to help promote changes to behaviors and actions ...
