This Subproduct will be preparing quarterly Fact Sheets, Summaries, Presentations, International updates. These quarterly meetings will be held with representatives of OITA, ORCR, and regional offices to provide updates on new development in Plastics research in terms of manageme...

International Workshop Presentations and Materials: Environmental exposures and public health.&nbsp; John will be presenting on the broad topic of Environmental priorities and intervention strategies.&nbsp; The attached presentations will be provided to the international audience...

Seagrasses are often touted for their ability to remove CO2 from the water and sequester it in the sediments as &ldquo;Blue Carbon&rdquo;. &nbsp;Further, seagrasses have been hypothesized to be refugia for calcifying organisms that are sensitive to coastal acidification. &nbsp;Ho...

Smooth cordgrass&nbsp;Spartina alterniflora&nbsp;and Atlantic ribbed mussels&nbsp;Geukensia demissa&nbsp;have a mutualism whereby&nbsp;S. alterniflora&nbsp;provides substrate and shade for&nbsp;G. demissa&nbsp;while&nbsp;G. demissa&nbsp;enhances&nbsp;S. alterniflora&nbsp;growth a...

Many coastal states throughout the USA have observed negative effects in marine and estuarine environments caused by cyanotoxins produced in inland waterbodies that were transported downstream or produced in the estuaries. Estuaries and other downstream receiving waters now face ...

Development of effective pollution mitigation strategies require an understanding of the pollution sources and factors influencing fecal pollution loading. Fecal contamination of Turkey Creek in Gulfport, Mississippi, one of the nation's most endangered creeks, was studied throug...

With increasing concerns about freshwater cyanobacteria blooms, there is a need to identify which waterbodies are at risk for developing these blooms, especially those that produce cyanotoxins. To address this concern, we developed spatial statistical models using the US National...

Supercritical Water Oxidation (SCWO) process for hazardous waste destruction uses the temperature and pressure of water above the critical point (374 oC, and 22.1 MPa) to degrade hazardous organic pollutants into CO2, water, SO2, and other benign compounds. Using SCWO technology ...

This study assessed the impact of brownfield sites, categorized by cleanup and redevelopment status, on nearby property values in Fulton County GA. &nbsp;Data on location and status of brownfield sites were obtained from EPA&rsquo;s Assessment, Cleanup and Redevelopment Exchange ...

In-situ measurements of optically active indicators of water quality are used to develop and validate spatiotemporally robust and cost-effective satellite remote sensing algorithms. Outputs from water quality algorithms routinely inform policymaker decisions that impact environme...

The first phase of a national scale Soil and Water Assessment Tool (SWAT) model calibration effort at the HUC12 (Hydrologic Unit Code 12) watershed scale was demonstrated over the Mid-Atlantic Region (R02), consisting of 3036 HUC12 subbasins. An R-programming based tool was devel...

Per- and polyfluoroalkyl substances (PFASs) have been detected in an array of environmental media due to their ubiquitous use in industrial and consumer products as well as potential release from fluorochemical manufacturing facilities. During their manufacture, many fluorotelome...

The aquatic environment has been recognized as a source of antibiotic resistance (AR) that factors into the One Health approach to combat AR. To provide much needed data on AR in the environment, a comprehensive survey of antibiotic-resistant bacteria (ARB), antibiotic resistance...

Thyroid hormones (TH) are important to numerous bodily functions such as development and homeostasis and can be useful bellwethers for identifying biologically disruptive compounds. Research into the effects of environmental pollutants such as pesticides and other endocrine disru...

Concerns about the safety of manufacturing and using engineered nanomaterials (ENMs) have been increasing as the technology continues to expand. Efforts have been underway to investigate the potentially harmful effects of ENMs without carrying out the challenging empirical studie...

Shallow continental shelves support productive pelagic and benthic communities. This study examined primary productivity at a shallow shelf region in the northeastern Gulf of Mexico focusing on the effect of light on water column and benthic productivity at water depths between 1...

This webinar was presented as part of the EPA-ORD Water Research webinar series on October 29, 2014. Dr. Tom Speth and Dr. Darren Lytle provided an overview of EPA’s small-system’s research and outreach efforts to communities, including topics like harmful algal blooms treatment,...

Our previous work has shown that the Jackson Lakes, in the Bayou Chico Watershed in NW FL, USA, are biogeochemically different and have different microbial communities, despite their proximity and common origin. All three lakes are polymictic, but the NE lake is fully freshwater,...

The ELISA assay is a potential tool to screen for dissolved or cell bound microcystins in drinking water treatment plant sludges. &nbsp;In order to evaluate this potential more thoroughly, a series of experiments were performed to: (1) evaluate the impacts of storage times and te...

A financially and technically accessible method for screening powdered activated carbons for control of HAB toxins in water treatment.

Develop genus&nbsp;level, trait based&nbsp;multimetric diatom index (MMI) to&nbsp;assess ecological condition of&nbsp;rivers/streams across U.S. Compliment NRSA Macroinvertebrate/Fish MMIs.

Introduction: Acrolein is a significant component of anthropogenic and wildfire emissions, as well as cigarette smoke. Although acrolein primarily deposits in the upper respiratory tract upon inhalation, patterns of site-specific injury in nasal versus pulmonary tissues are not w...

Background:&nbsp;Prescribed fires often have ecological benefits, but their environmental health risks have been infrequently studied. We investigated associations between residing near a prescribed fire, wildfire smoke exposure, and heart failure (HF) patients' hospital utilizat...

Benthic diatoms are highly responsive to changes in environmental conditions associated with human activities. Their changes in assemblage structure can be used to develop stressor-response relationships, metrics, and indices that can help identify effects of pollution and inform...

Identification of potential pathogens that present risks to human health in recreational waters is necessary to advance in-depth water quality assessments. Despite the application of PCR techniques for environmental pathogen detection, only limited information is usually availabl...
