US EPA has previously published a decision support tool (River Basin Export Reduction Optimization Support Tool, RBEROST) populated with data for the Upper Connecticut River Basin to allow stakeholders to determine the least-cost management strategies to meet nitrogen and phospho...

Plastic pollution is ubiquitous worldwide. Smaller pieces of plastic (<5 mm) denominated as microplastics (MPs) are of particular concern because they can be easily transported throughout the environment. As they travel, MPs can adsorb chemicals or nutrients, and develop a biofil...

The analysis of contaminants of emerging concern (CECs) has been an ongoing priority due to their potential for adverse effects on environmental and human health. Wastewater is a source for many CECs, and surface waters that receive wastewater discharge often serve as source wate...

The Pawcatuck River flows through Westerly, Rhode Island before discharging into Little Narragansett Bay. The Pawcatuck River has a long history of pollution associated with textile and dye manufacturing due to historic mill operations along the riverbank. Operations at the Bradf...

The extent to which chemicals bioaccumulate in aquatic and terrestrial organisms represents a fundamental consideration for chemicals management efforts intended to protect public health and the environment from pollution and waste. Many chemicals, including most pharmaceuticals ...

Per- and Polyfluoroalkyl substances (PFAS), also known as &ldquo;forever chemical&rdquo; are a complex group of over 4800 manufactured chemicals that are ingredients in various everyday products. The wide-spread use of PFAS in different applications ranging from non-stick surface...

This is a requested presentation for the Association of Clean Water Administrators (ACWA) that discusses how ORD is the research arm of the EPA and provides the scientific foundation for EPA to execute its mandate to protect human health and the environment. An overview of the 6 ...

This presentation will review the latest research on inputs, budgets, effects, legacies and management related to non-point source nutrient pollution.&nbsp; Using examples of phosphorus budgets at the national, regional and local scales, Jana Compton from EPA&rsquo;s Pacific Ecol...

These workshops will be platform to present recent research at EPA as it relates to best practices in site characterization, sample analysis, and suitable treatment technologies for mining, persistent organic pollutants, and microplastics. The first presentation will be expanding...

Elevated temperature landfills (ETLFs) are municipal solid waste (MSW) landfills that have been impacted by subsurface exothermic reactions (SERs) and display unusual gas and leachate composition. Leachate quantity and quality data were analyzed to identify indicators of a SER. A...

Climate change has created the need for innovate methods for the management of groundwater and the augmentation of groundwater supplies in areas that are susceptible to drought as well as other climate related problems such as saltwater intrusion. This will create an enhanced dep...

This work investigated the suitability of three non-hazardous food dyes as PFAS simulants during wastewater treatment with powdered activated carbon (PAC). Data from batch experiments with PAC revealed equilibrium constants (Log Kd) and pseudo first-order adsorption rate constant...

Background and Purpose Biosolids are treated sewage sludge produced as a byproduct of the wastewater treatment process, often applied to land or disposed of in landfills. Under the Clean Water Act, the US EPA Office of Water (OW) has the responsibility to protect human health and...

Presentation to Southwest Ohio Water Environment Association Industrial Waste Seminar.&nbsp; Overview of the Renewable Fuel Standard and its relation to wastewater utility biogas production.

Whole Effluent Toxicity (WET) test methods for measuring the toxicity of effluents and receiving waters are found in 40 CFR Part 136. Short-term chronic freshwater toxicity test methods include the use of three species &ndash; a cladoceran (Ceriodaphnia. dubia), the fathead minno...

Presentation that outlines the process for developing a research plan for a BILS funded research project that is designed to develop validatable methods for detection and quanitation of emerging and historically important pathogens in raw and treated wastewater.

Presentation outlining prospective dissertation research on the Fate and Transport of wastewater linked contaminants. Research investigates the environmental, spatial, temporal, and laboratory methodological trends in monitoring wastewater impacts to surface water.

The purpose of this lecture is to provide a summary of the EPA's research activities with regards to waterborne protozoa with specific emphasis on methods development to detect Cryptosporidium Giardia, and Toxoplasma gondii.

Chemicals of concern may pose an unreasonable risk to human health and the environment across their life cycle stages. Risk assessment at the end-of-life (EoL) stage is of critical importance due to differing chemical management methods that result in possible exposure scenarios....

Wastewater is a source for many contaminants of emerging concern (CECs) and surface waters receiving wastewater discharge often serve as source water for downstream drinking water treatment plants. Non-targeted analysis and suspect screening methods were used to characterize chem...

An analysis was conducted of the Chicago metropolitan region using the following integrated metrics: Fisher Information, Green Net Metropolitan Product, Net Energy, Ecological Footprint, Human Well Being Index, and Emergy. Data were aggregated as they were available, over a multi...

US EPA has previously published a decision support tool (River Basin Export Reduction Optimization Support Tool, RBEROST) populated with data for the Upper Connecticut River Basin to allow stakeholders to determine the least-cost management strategies to meet nitrogen and phospho...

The lack of standardized methods and large differences in virus concentration and extraction workflows have hampered Severe Acute Respiratory Syndrome (SARS-CoV-2) wastewater surveillance and data reporting practices. Numerous studies have shown that adsorption-extraction (AE) me...

It is becoming a necessity to provide resource constrained small public water utilities with diverse, cost-effective, low-technology and sustainable alternatives for removing arsenic and other contaminant clusters in order to provide safe drinking water.Chitosan-coated Diatomaceo...
