The National Aquatic Resource Surveys (NARS) program, a collaboration among United States Environmental Protection Agency (US EPA) Office of Water, Office of Research and Development (ORD), and states and tribes, assesses progress towards the objective of the Clean Water Act thro...

EPA-ORD-CPHEA's Michael Pennino and Jana Compton were invited to present on groundwater nitrate at SSWR’s Quarterly Research Area Coordination Team (RACT) meeting for the Nutrients topic SSWR.4 on June 5,  2024.  This meeting brings together the research coordinat...

Diatoms and soft algae have been collected by state monitoring programs across the United States to assess the biological condition of lotic and lentic water bodies. Some of the state programs have long-term records (i.e., decades) of algal taxonomic data. Over time, changes in l...

Taxonomic data are the foundation of bioassessment and much basic and applied research. Difficulty in morphological species identification, evolving and varying taxon concepts, and nomenclatural changes can lead to significant inconsistencies in taxonomic datasets across analysts...

These slides introduce EPA ORD's Living Shorelines public education session for the community of Crisfield, MD, as part of co-development of research on nature-based strategies for coastal resilience. The goal is to help build knowledge capacity around living shoreline functional...

Analytical methods, specifically those focused on the identification of chemicals by liquid and gas chromatography mass spectrometry (LC/MS and GC/MS), are key approaches supporting targeted and non-targeted environmental analysis. Different chemicals and chemical classes are ame...

Introduction (120/120): The US EPA is developing new approach methodologies (NAMS) to rapidly evaluate thousands of data-poor chemicals for human health hazards. These NAMs include in vitro exposures to investigate chemical metabolism in novel cell systems to inform hazard a...

Aquatic ecosystem resilience to wildfire can vary widely depending on the characteristics of fire and the spatial context of where a fire takes place. Researchers at EPA’s Office of Research and Development are collaborating with the US Forest Service, and Oregon State Univ...

Presentation about research using trail cameras as input data to a neural network machine learning model to inform on streamflow.

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...

Presentation for the Clean Water Act 303(d) training workshop that discusses lessons from data collection at stream and lake Regional Monitoring Network sites. The presentation also covers novel monitoring approaches using trail cameras.

The effect of wildfire on aquatic habitat over time is not well understood, especially in the Pacific Northwest, and relies on the collection of ongoing data over long time periods. In Western Washington, Oregon, and Northern California, the Aquatic and Riparian Effectiveness Mon...

Drinking water nitrate contamination is a significant economic and public health concern in The Great Plains, with few tested best practices for improving source water quality. This project seeks to establish a monitoring framework for quantifying the benefits of soil health prac...

Legionella pneumophila (Lp) is an opportunistic pathogen that causes respiratory infections primarily through inhalation of contaminated aerosols. Lp can colonize premise plumbing systems due to favorable growth conditions found within those environments (e.g. lower disinfectant ...

In this LifeNet Health webinar, Dr. Deisenroth introduces an advanced human in vitro 3D thyroid microtissue model designed to evaluate thyroid hormone disruption, addressing current challenges with existing models. He will discuss the US EPA Endocrine Disruptor Screening Program’...

Background and Purpose Organophosphorus flame retardants (OPFRs) are abundant and persistent in the environment due to their extensive use in industrial processes and products. In vivo and in vitro studies suggest that OPFRs may cause adverse health effects. Additionally, their s...

Analytical methods can vary in nature from detailed regulatory methods to more summary in nature. Regulatory method documents can include details of analytes which can be studied, supported matrices, reagents, methodological details, statistical performance, interlaboratory valid...

The Equitable Resilience Builder (ERB) is a downloadable application that for enhancing community engagement and equity in resilience planning. The tool provides guidance and activities for assessing community resilience needs and identifying actions. Activities include network m...

Introduction The Integrated Risk Information System (IRIS) assessment for trichloroethylene (TCE) found that human data were sufficient to support dose-response modeling and to develop an inhalation unit risk (IUR) for renal cell carcinoma (RCC). However, human and rodent data su...

Many aqueous film forming foam (AFFF) delivery systems in aircraft hangars and firefighting vehicles may require thorough cleaning to avoid ongoing environmental impacts from residual per- and polyfluoroalkyl substances (PFAS) within those systems. Though replacement AFFF formula...

Large-scale disasters have the potential to generate a significant amount of waste. For example, Hurricane Katrina and the Joplin Missouri tornado resulted in 100 million and 1.5 million cubic yards of waste, respectively. Man-made chemical, biological, radiological, or nuclear (...

SAAOP Invited presentation to highlight interoperability of EPA Adverse Outcome Pathway Database (AOP-DB) with the AOP-wiki.

Argonne is building an intelligent computer application, the Radiological Recovery Logistics Tool (RRLT), to assist the understanding and allocation of resources for a mitigation and recovery effort. RRLT output will be a list of recommended methods and tools to accomplish the sp...
