Wild pigs are an invasive species found globally that pose significant economic impact and a serious risk to local ecosystems, agriculture, and public health. Fecal contamination of water is one of these public health concerns as wild pigs have been shown to carry pathogenic ente...

Particulate Matter is one of the six major air pollutants for which EPA has issued air quality criteria and established national ambient air quality standards (NAAQS) based on those criteria. The Clean Air Act (CAA) requires EPA to periodically review and revise, as appropriate, ...

Numerous qPCR-based methods are available to estimate the concentration of fecal pollution sources in surface waters. However, qPCR fecal source identification data sets often include a high proportion of non-detections (reactions failing to attain a prespecified minimal signal i...

The relative role of natural and anthropogenic drivers on freshwater biodiversity across different aquatic ecosystem types is not well understood. The U.S. Environmental Protection Agency&rsquo;s National Aquatic Surveys (NARS) offers a unique opportunity to compare lentic and lo...

Wildland fire smoke impacts millions of people in the United States every year. The EPA&rsquo;s Office of Research and Development is addressing our increasingly smokey future with state-of-the-art instrumentation in a mobile air quality laboratory based at the PESD lab in Corval...

INTRODUCTION: Coccidioidomycosis is an emerging fungal infection caused by inhalation of airborne spores of the Coccidioides genus. While Coccidioides immitis has been detected in soils across California, successful recovery of C. immitis from air samples has so far been limited ...

Quantifying the influence of environmental factors on species distributions can elucidate their ecological requirements and potential response to anthropogenic disturbance. Single species distribution models are commonly used to quantify taxon-environment relationships but do not...

This research builds upon successful StRAP 3 (Appendix B) and RARE project tests of ORD's VELMA ecohydrology model to identify urban GI solutions for reducing stormwater contaminant loads impacting ESA-listed salmonids in the Puget Sound National Estuary. For example, recent resu...

Long-term monitoring datasets provide valuable opportunities to identify aquatic ecosystem responses to disturbance at broad spatial extents. The Aquatic and Riparian Effectiveness Monitoring Program (AREMP) is unique in this regard because the program re-surveys the same 1411 st...

EPA-ORD-CPHEA's Michael Pennino, Jana Compton and Robert Sabo were invited to present on groundwater nitrate at joint meeting with USDA-NRCS on May 22, 2024.&nbsp; This meeting brings together the USDA Agricultural Water Quality National Team together with US EPA scientists and s...

As the world's reservoirs experience drawdowns from reduced precipitation and increased water demand, expanses of sediment are being exposed and colonized by both native and non-native vegetation. Within Lake Powell, the second largest reservoir in the U.S., drought in the Colora...

The U.S. Environmental Protection Agency (EPA) is conducting a review of the air quality criteria and the secondary (welfare-based) national ambient air quality standards (NAAQS) for nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM). The major phases of the ...

Ozone is one of the six major air pollutants for which EPA has issued air quality criteria and established national ambient air quality standards (NAAQS) based on those criteria. The Clean Air Act (CAA) requires EPA to periodically review and revise, as appropriate, existing air ...

The Clean Air Act establishes a two-stage regulatory process for addressing emissions of hazardous air pollutants (HAPs) from stationary sources. In the first stage, the Act requires the EPA to develop technology-based standards for categories of industrial sources. We have lar...

Sulfur oxides are one of the six major air pollutants for which EPA has issued air quality criteria and established national ambient air quality standards (NAAQS) based on those criteria. The Clear Air Act (CAA) requires EPA to periodically review and revise, as appropriate, exis...

NO2 is one of the six major air pollutants for which EPA has issued air quality criteria and established national ambient air quality standards (NAAQS) based on those criteria. The Clean Air Act (CAA) requires EPA to periodically review and revise, as appropriate, existing air qu...

Platform presentation at the 41st Veterinary Comparative Respiratory Society meeting on Lung Damage and Repair, Providence RI Oct. 23-25, 2023 October is Children&rsquo;s Health Month. As a vulnerable population, children are often more susceptible to the damaging effects of poll...

This presentation gives a brief overview of key research findings related to extreme heat and health, suitable for an 8-10 minute presentation. We highlight key findings related to urban heat islands, cardiovascular outcomes, and respiratory outcomes, and provide context for the ...

Neurodevelopment is a period vulnerable to various insults, including those produced by environmental compounds, and an understanding of these effects continues to be needed. Although in vitro New Approach Methodologies (NAMs) are being developed to foster efficient assessment of...

The six PFAS we have studied (PFOA, GenX, PFMOAA, PFOS, NBP2, PFHxS) produced multiple common effects across all compounds, however the compounds were not toxicologically identical.&nbsp; Effects common across all compounds included reduced pup and maternal bodyweights, reduced p...

Webinar for CALFIRE Prescribed fire is a forest management strategy for reducing risk of wildfires. This study examined the change in cardiorespiratory health impacts (emergency department visits) that could result from an expected increase in the use of prescribed fire in Califo...

We hypothesized that stress caused by high-temperature housing and episodic subchronic wildfire-related eucalyptus smoke exposure (WFES) would interact to disrupt pulmonary, cardiovascular, and metabolic health. Male Wistar-Kyoto rats (4 weeks of age) were exposed to thermal stre...

Burn pits are a method of open-air waste management that was common during military operations in Iraq, Afghanistan, and other regions in Southwest Asia. Veterans returning from deployment have reported respiratory symptoms, potentially from exposure to burn pit smoke, yet compre...

Altered lake hydrology is an emerging, widespread threat as changing climate conditions and increasing human water use place greater pressure on water resources. Dam and land use management can significantly alter lake water-level regimes and flow characteristics, which in turn c...

This presentation describes the development of a decision support tool, the Priority Response Environmental Screening Tool (PRESTO), that was designed to provide a framework for analyzing geospatial information. The objective of a PRESTO analysis is to assist the U.S. Environment...
