US EPA initiated a study in the Tillamook estuary and watershed focused on the impact of changes in watershed land use, ocean conditions, and weather on estuarine water quality and ecosystem goods and services production within the estuary. This project is a collaboration betwee...

A novel method using a micro-ion-selective electrode (micro-ISE) technique was developed for in situ lead monitoring at water-metal interface of a brass-leaded solder galvanic joint in a prepared chlorinated drinking water environment. The developed lead micro-ISE (100 µm tip di...

Arsenic (As) is the most frequently occurring contaminant on the priority list of hazardous substances, which lists substances of greatest public health concern to people living at or near U.S. National Priorities List site. Accurate assessment of human health risks from exposure...

Corrosion in water-distribution systems is a costly problem and controlling corrosion is a primary focus of efforts to reduce lead (Pb) and copper (Cu) in tap water. High chloride concentrations can increase the tendency of water to cause corrosion in distribution systems. The ...

Roughly eight million people live on Long Island, including Brooklyn and Queens, and despite improvements in wastewater treatment, nearly all its coastal waterbodies are impaired by excessive nitrogen. We used nutrient stoichiometry and stable isotope ratios in estuarine biota an...

Diadromous fish populations in the Pacific Northwest face challenges along their migratory routes from declining habitat quality, harvest, and barriers to longitudinal connectivity. Changes in river temperature regimes are producing an additional challenge for upstream migrating ...

Forest disturbance regimes are beginning to show evidence of climate-mediated shifts associated with global climate change, and these patterns will likely continue due to continuing changes in environmental conditions. Tree growth is largely controlled by the physiological const...

Version 3 of EPA&rsquo;s Watershed Management Optimization Support Tool (WMOST) will be released in early 2018 (https://www.epa.gov/exposure-assessment-models/wmost). WMOST is designed to facilitate integrated water management among communities, utilities, watershed organization...

All people are exposed to complex and dynamic mixtures of chemicals and nonchemical stressors throughout their lives. Understanding how these combined exposures impact human health is an active area of research spanning exposure science, toxicology, epidemiology, statistics, and ...

Permeable pavement is a stormwater control measure commonly selected in both new and retrofit applications. However, there is limited information about the clogging mechanism of these systems that effects the infiltration. A permeable pavement site located at the Seitz Elementary...

This paper addresses United States Environmental Protection Agency (EPA) operational and research challenges for the next decade in the utilization of space-based observations for the assessment of terrestrial properties affecting land, water, and air resources, and human health....

Water quality is essential for the survival of life, population health and well-being. No current or planned earth orbiting mission is optimized for water quality measures of inland waters (lakes and reservoirs) or estuaries. A combined science- and application- driven, long-term...

Undertaking large-scale aquatic habitat restoration projects in prominent waterfront locations, such as city parks, provides an opportunity to both improve ecological integrity and enhance community well-being. However, to consider both opportunities simultaneously, a community-b...

Geographically isolated wetlands, those entirely surrounded by uplands, provide numerous landscape-scale ecological functions, many of which are dependent on the degree to which they are hydrologically connected to nearby waters. There is a growing need for field-validated, lands...

Mosquito-borne diseases are an increasingly important health concern, which pose great challenges for safe and sustainable control and eradication. This reality calls for management approaches that consider multiple aspects of the transmission cycle from a landscape and vector ec...

Climate-change driven increases in water temperature pose multiple challenges for aquatic organisms. Predictions of climate change impacts to biota typically do not account for fine-grained spatiotemporal patterns of stream networks; yet patches of cooler water within rivers c...

Sustainable efforts in greener assembly of nanoparticles and their diverse applications as nano-catalysts are gaining importance in catalysis arena [1]. Vitamins B1, B2, B12, C, beet juice, and phenolic antioxidants from a variety of sources assist in ready access to bulk quantit...

The U.S. Environmental Protection Agency National Stormwater Calculator (NSWC) simplifies the task of estimating runoff through a straightforward simulation process based on the EPA Stormwater Management Model. The NSWC accesses localized climate and soil hydrology data, and opti...

Watershed integrity is the capacity of a watershed to support and maintain the full range of ecological processes and functions essential to sustainability. We evaluated and mapped an Index of Watershed Integrity (IWI) for 2.6 million watersheds in the conterminous US using firs...

The spatial arrangement of urban vegetation depends on urban morphology and socio-economic settings. Urban vegetation changes over time because of human management. Urban trees are removed due to hazard prevention or aesthetic preferences. Previous research attributed tree loss t...

Both Minnesota and Wisconsin have posted fish consumption advisories within the St. Louis River Area of Concern (SLR AOC), in part because fish have elevated mercury concentrations. To assess mercury concentrations in fish tissue within the SLR AOC relative to reference condition...

Freshwater fish are ecologically important in stream ecosystems, and they provide significant value to humans. Historically, the streams and rivers of southern New England supported moderately diverse and abundant assemblages of native fishes. Currently, these habitats are impact...

The importance/longevity of galvanic corrosion as a mechanism of toxic lead release into drinking water has been under scientific debate in the U.S. for over 30 years. Visual and mineralogical analysis of 28 lead pipe joints, excavated after 60+ years from 8 U.S. water utilities,...
