EPA-ORD-CPHEA's Michael Pennino and Jana Compton were invited to present on groundwater nitrate at the EPA Region 5 State Water Directors Meeting on May 15, 2024.&nbsp; This meeting brings together EPA Region 5 state clean water and drinking water directors to discuss topics of c...

This Subproduct is a slide deck for an invited presentation at the Georgetown University Center for PFAS and Cancer (CPAC) Joint Virtual Symposium.&nbsp; Slide deck presents the results of our group's PFAS developmental toxicity mixture studies.&nbsp; This work demonstrates the d...

Identifying reliable positive and negative control compounds is integral to determining the sensitivity and specificity of chemical assays. Our laboratory screens chemicals for developmental neurotoxicity potential using assays that assess larval zebrafish locomotor behavior in r...

Combustion of mixed materials during open air burning of refuse and housefires produces emissions that worsen air and water quality and cause adverse health effects. The purpose of this study was to assess the irritant potential of extractable organic material of smoke condensate...

This study characterized Bacillus globigii (BG) as a Bacillus anthracis Sterne (BAS) surrogate for wastewater treatment-related studies of UV inactivation, adsorption onto powdered activated carbon (PAC), and bioaerosol emission. The inactivation of BG was faster than that of BAS...

Protein processing operations utilize large volumes of water for hair/hide/feather removal, carcass washing, chilling, trimming and cutting, cooking, cleaning and sanitation, etc. The generated wastewater is typically treated onsite and discharged to municipal wastewater treatmen...

Medical professionals are interested in using remote monitoring to identify at-risk populations, reduce outcome disparities, and provide timely interventions to vulnerable patients. We examined the effect of warm season weather conditions on the risk of ventricular tachycardia/ve...

Presentation for PIC 2024 meeting 74% of U.S. firefighters are reproductive age (20 &ndash; 49 y.o.; 2019) &bull; 92% of U.S. firefighters are male (2019) &bull; A decrease from 99% in the 1980s (Perroni et al. 2021, PLoS One) &bull; Male reproductive tract may be particularly se...

Invited presentation to SKIG AOP interest group to the SAAOP. Brief introduction to AOP-DB v.2 updates. Full presentation invited to follow at June meeting.

Distribution system nitrification is an important issue for water utilities that use chloramines as a secondary disinfectant. This presentation reviews the causes of nitrification and how to monitor, prevent, and react to nitrification events. Furthermore, an update on research n...

The Final ecosystem goods and services (FEGS) concept has become increasingly valuable for identifying and evaluating important trade-offs in estuarine management, yet the translation of FEGS science into policy is limited by a need for meaningful reference points that facilitate...

Due to some Per and Polyfluoroalkyl substances (PFAS) having both hydrophilic and hydrophobic components on the same structure, they are often found at the interface between air and water. This behavior results in PFAS concentrating in the surface microlayer. When surface water i...

The RESES team worked, with extensive input from the community, to identify the ecosystem services that the Ouachita River provide and how that contributes to the community&rsquo;s well-being. The work began by identifying the community&rsquo;s values and goals and how they contr...

Evaluating long-term contaminant effects on wildlife populations depends on spatial information about habitat quality, heterogeneity in contaminant exposure, and sensitivities and distributions of species integrated into a systems modeling approach. Rarely is this information rea...

Understanding saltwater intrusion into freshwater coastal wetlands requires long-term historical salinity data, which are often not available in most tidal river systems. This study developed an artificial neural network (ANN) modelling tool to elucidate the relationship between ...

Gulf Ecology Division research ecologist Dr. Deborah Santavy, along with Susan Jackson from the Office of Water&rsquo;s Office of Science and Technology (OW-OST), presented a webinar on July 16, 2019 to update our NOAA partners in the Coral Reef Conservation Program on the fish a...

oral presentation based off of multiple abstracts already cleared on this topic describing the chemistry and toxicology of combustion emissions from various sources.&nbsp; Conceptual Approach.&nbsp; Compare the relative cardiopulmonary toxicity and mutagenicity of smoke either fr...

Background: Extreme heat events from climate change are classified as the leading cause of weather-related death in the United States and are associated with cardiovascular morbidity and mortality. Potential synergistic effects of housing (ie. psychosocial stress) with extreme he...

EPA&rsquo;s Endocrine Disruptor Screening Program (EDSP) was established in 1998 to identify chemicals that disrupt human endocrine system signaling. EDSP has the potential to support the regulation of pesticides under FIFRA, the Federal Insecticide, Fungicide, and Rodenticide Ac...

In 2014 a new Chesapeake Bay Watershed Agreement was adopted that included headwater states for the first time and outlined goals for implementation of several BMPs focused on restoration and conservation of vital habitats. At the watershed scale, however, implementation goals as...

This presentation contributes to the SoCal Pb symposium which seeks to raise awareness, share knowledge, and discuss actionable next steps towards solutions to reduce lead risk in LA.

Overview presentation on ORD&rsquo;s Technical Assistance Program for Emerging Contaminants

This presentation provides a critical review of state and federal initiatives and peer-reviewed literature to define best practices for managing PFAS-containing solid wastes and identify data gaps to guide future research. The objective is to inform stakeholders about waste-deriv...

To present EPA PFAS research to the primacy agency and small drinking water utilities in Idaho.&nbsp;

PFAS are ubiquitous, persistent, and bioaccumulate in the environment. Thermal treatment methods are currently applied to a variety of PFAS-containing materials, including sewage sludge and granular activated carbon (GAC), but may not be sufficient to fully mineralize organic flu...
