There is always a challenge of obtaining the &ldquo;best&rdquo; data to inform environmental models. Here we present different types of available precipitation datasets while detailing temporal and spatial resolution, potential errors in the dataset, and optimal performance scena...

Despite its importance to transportation safety and ecosystem health related to pollutant and nutrient deposition, the simulation of fog lags the simulation of other meteorological phenomena due in large part to its complexity and limitations of model resolution. Accordingly, th...

Environmental surface waters often contain a variety of chemical contaminants from different sources including wastewater treatment plants, concentrated animal feeding operations, agricultural runoff and other human-related activities. Exposure to these contaminants may pose a th...

Green infrastructure (GI) represents a broad set of stormwater control measures practices that can be flexibly implemented to increase sewershed retention capacity, and can thereby improve on the management of water quantity and quality. Although much GI presents as formal engine...

High-resolution mass spectrometry (HRMS) data has revolutionized the identification of environmental contaminants through non-targeted analysis (NTA). However, chemical identification remains challenging due to the vast number of unknown molecular features typically observed in ...

Trenbolone acetate is widely used in some parts of the world for its desirable anabolic effects on livestock. Several metabolites of the acetate, including 17β‐trenbolone, have been detected at low nanograms per liter concentrations in surface waters associated with animal feedlo...

Video documentation was obtained of the invasive benthic fish, Neogobius melanostomus, the round goby, feeding on crushed dreissenid mussels at a depth of 12 m in Georgian Bay of Lake Huron, Canada. Gobies used rotational or twist feeding to tear away particles from crushed musse...

We developed and then used a flowchart to identify example specific conductivity (SC) hazardous concentration (HC05) values for 63 of the 85 Level III ecoregions in the conterminous United States. Using the flowchart, we compared SC HC05 values estimated at the mean regression l...

The Adverse Outcome Pathway (AOP) framework represents an ideal tool for integrating diverse data relating chemical exposures to adverse outcomes. Glucocorticoid signaling is tightly controlled and numerous adverse health outcomes have been associated with either elevation or sup...

Cyanobacterial harmful algal blooms are the most common form of harmful algal blooms in freshwater systems throughout the world. However, in situ sampling of cyanobacteria in inland lakes is limited both spatially and temporally. Satellite data has proven to be an effective tool ...

The Nooksack-Fraser transboundary area is home to communities with a strong base in farming, fisheries and outdoor recreation. A goal of the Nooksack-Fraser Transboundary Nitrogen (NFT-N) project is to determine the sources and fates of N in the watershed using data on energy us...

Indicators of a stream&rsquo;s ability to remove nutrients provide insights on watershed integrity and stream habitat characteristics that are needed to help managers to restore stream ecosystem services. We used the Tracer Additon Spiraling Characterization Curve (TASCC) to mea...

Indicators of a stream&rsquo;s ability to remove nutrients provide insights on watershed integrity and managers&rsquo; ability to restore ecosystem services based on specific characteristics of stream habitat. We used the Tracer Additon Spiraling Characterization Curve (TASCC) t...

Life cycle assessment (LCA) is a tool that aids in sustainable decision-making among product and process alternatives. When implementing LCA, the efficient and accurate modeling of chemical processes for life cycle inventory (LCI) generation is still challenging. Challenges inclu...

This paper reports on the pilot testing of a new bioassay platform that monitors expression of 1600 genes in zebrafish embryos exposed to either single chemicals or complex water samples. The method provides a more cost effective, high throughput means to broadly evaluate the pot...

Water quality degradation is a chronic problem which influences the resilience of a social-ecological system differently than acute disturbances, such as disease or storms. Recognizing this, we developed a tailored resilience framework that applies ecosystem service concepts to c...

The deleterious effects of microplastic ingestion by marine organisms and the impacts across trophic levels are widely unknown. Due to the extensive ecological and socioeconomic benefits provided by coral reefs, investigating the impacts of microplastics on reef ecosystems is of ...

WNTR integrates hydraulic and water quality simulation, a wide range of damage and response options, and resilience metrics into a single software framework, allowing for end-to-end evaluation of water network resilience. WNTR includes capabilities to 1) generate and modify water...

To date, most research focused on developing more efficient and cost effective methods to predict toxicity have focused on human biology. However, there is also a need for effective high throughput tools to predict toxicity to other species that perform critical ecosystem functio...

This presentation discusses &quot;accountability&quot;; e.g., do emission-control regulations really reduce exposure to pollutants and improve human health? In this presentation, we provide examples of how to examine this and related questions.

This fact sheet provides information about EPA's Ada, OK facility, Robert S. Kerr Environmental Research Center, and will be available to the public.

The multivariate AMBI (M-AMBI) is an extension of the AZTI Marine Biotic Index (AMBI) that has been used extensively in Europe, but not in the United States. In a previous study, we adapted AMBI for use in US coastal waters (US AMBI), but saw biases in salinity and score distribu...

The Model for Prediction Across Scales &ndash; Atmosphere (MPAS-A) has been modified to allow four-dimensional data assimilation (FDDA) by the nudging of temperature, humidity, and wind toward target values predefined on the MPAS-A computational mesh. The addition of nudging allo...

In estuaries, land-surface and tidal elevation conspire to influence the amount of salt-water inundation in a specific location, ultimately affecting the distribution of estuary vegetation. Plants vary in their tolerances to salinity and inundation. Understanding even small chang...

Atmospheric models that accurately describe the fate and transport of trace species for the right reasons aid in the development of effective air-quality management strategies that safeguard human health. Controllable emissions facilitate the formation of biogenic secondary organ...
