Biodiesel production from soybean has been growing in the United States and although its amount is small by comparison with corn ethanol, its addition to existing demands on land can have nonlinear effects on land use, due to an upward sloping and increasingly inelastic supply of...

A laboratory-scale study simulating a full-scale hazardous waste incinerator was intended for the destruction of selected per- and poly-fluoroalkyl substances, PFAS. This study aimed to determine if incineration is a potentially effective way of destroying PFAS. Ten PFAS compound...

This presentation presents an overview of select SSWR research from StRAP3 addressing nutrients, HABs, and hypoxia. Research includes presentation of national watershed nutrient inventories, freshwater phytoplankton qPCR, legacy nutrients, estuarine nutrient resilience and recove...

Under this effort we will develop a validation plan for TEMPO Level 2 geophysical products in collaboration with Smithsonian Astrophysical Observatory, NASA, and NOAA. The validation plan will include a focus on better addressing the air quality management needs of EPA and state ...

This presentation will cover EPA ORD's work to use human mobility data derived from cellular device locations to estimate visitation to natural areas, including beaches and parks. We will cover our process, results and published results. We will discuss the current and future pla...

The data are a subset of the EPA Dynamically Downscaled Ensemble (EDDE), Version 1. EDDE is a collection of physics-based modeled data that represent 3D atmospheric conditions for historical and future periods under different scenarios. The EDDE Version 1 datasets cover the conti...

An important piece of building resilience in a community involves access to amenities and information. In coastal communities, flood waters can impact connectivity and leave many areas vulnerable in both the short and long term. The information presented will cover how the model ...

Describes health effects of PFOA and provides values for region and state use.

EPA is peer reviewing the Agency’s report modeling the relationship between lead in drinking water and blood lead levels in children utilizing the Integrated Exposure Uptake Biokinetic (IEUBK) model. The report being peer reviewed may be used to inform the derivation of a concent...

The area covered by the Pensacola and Perdido Bay Estuary Program is extenive, including two states, four counties, and numerous smaller communities. Vulnerability of each community is assessed either through social characteristics or physical exposures. Social vulnerability repr...

EPA has finalized the IRIS Toxicological Review of Perfluorodecanoic Acid (PFDA) and Related Salts. This assessment addresses the potential cancer and noncancer human health effects from exposure to PFDA and related salts. EPA’s program and regional offices may use this assessmen...

In July 2024, EPA finalized the IRIS Toxicological Review of Perfluorodecanoic Acid (PFDA) and Related Salts. The Toxicological Review was reviewed internally by EPA and by other federal agencies and White House Offices after public release in April 2023. Consistent with the May ...

The City of Pensacola is in the planning phases of a new stormwater park that it hopes will serve as a community hub between two neighborhoods that were separated by construction of an interstate. There is interest in both the social and environmental impacts of this park to both...

Many benthic indices have been created in the last two decades for monitoring coastal ecosystems, however direct comparisons between indices are often difficult. To address this, M-AMBIUS has replaced regional indices used by the US Environmental Protection Agency. Objectives of ...

Landfills manage materials containing per- and polyfluoroalkyl substances (PFAS) from municipal solid waste (MSW) and other waste streams. This manuscript critically reviews state and federal initiatives and peer-reviewed literature to define best practices for managing these was...

Jane Bare has been invited to speak at Fenwick High School’s Spring Career Expo on March 14th. The Career Expo is offered during the Fall and Spring semesters to all Fenwick students. These mini career conferences give students a chance to listen to a wide range of speakers to be...

It is postulated that below a transcriptomic-based point of departure, adverse effects are unlikely to occur, thereby providing a chemical concentration to use in screening level hazard assessment. The present study extends previous work describing a high-throughput fathead minno...

Maui’s water basins are an engineering tool to facilitate precipitation of sediment during weather events. Unfortunately, these basins only facilitate the precipitation of coarse sediment grain sizes, leaving the finer sediment to overflow into the ocean. As fine sediment h...

Establishing ecological protection goals for environmental contamination is rife with challenges and uncertainties. Spatial inhomogeneity, differential intra- and inter- species sensitivities, limited data on exposure and effects profiles, and an enormous diversity of ecological ...

Context: The number of publications that evaluate or use landscape connectivity has grown dramatically in recent years. But the biological realism of common connectivity assessments remains limited. To address this shortcoming, I introduce a flexible methodology for evaluating fu...

Classification systems can be an important tool for identifying and quantifying the importance of relationships, assessing spatial patterns in a standardized way, and forecasting alternative decision scenarios to characterize the potential benefits (e.g., ecosystem services) from...
