The Pawcatuck River Estuary (PRE), composed of the Pawcatuck River and Little Narragansett Bay (CT/RI, USA), is a coastal plain estuary subject to environmental stress. Anthropogenic nutrient loading, watershed land-use changes, and urbanization have contributed to eutrophication...

If a water body in the United States is not as healthy as we&rsquo;ve decided it should be, the most likely cause is nutrient pollution &lt;span style='mso-element:field-begin'&gt;&lt;span style='mso-spacerun:yes'&gt;&nbsp;ADDIN EN.CITE &lt;EndNote&gt;&lt;Cite&gt;&lt;Author&gt;US...

Although nitrogen (N) deposition has decreased in Europe and the United States for decades, &nbsp;considerable areas of the world &nbsp;will likely continue to receive high levels of N deposition in the future. Some soil chemical variables can respond quickly to declining N depos...

Peer review of nutrient assessment approach used in NRSA and other NARS.

In urban systems, a wide variety of processes, including increasing impervious surface cover, road salt application, sewage leaks, and weathering of the built environment, contribute to novel chemical cocktails that are comprised of metals, salts, nutrients, and organic matter. D...

This overview is designed for a general audience without expertise in satellite remote sensing and forecasting. It is meant to highlight how the Cyanobacteria Assessment Network, CyAN , might provide useful real-time data, software, training, annual summary metrics, and 1-week fo...

Data and analysis of water chemistry and lower food web for collaborative report

Data and analysis of water chemistry and lower food web for collaborative report. This dataset was an important part of the manuscript &quot;A modeling study to determine the contribution of interbasin versus intrabasin phosphorus loads on the southwestern nearshore of Lake Ontar...

Anthropogenic pollution of hydrological systems affects diverse communities and ecosystems around the world. Data analytics and modeling tools play a key role in fighting this challenge, as they can help identify key sources as well as trace transport and quantify impact within c...

In the Pacific Northwest, the dominant seagrass, Zostera marina occurs primarily in the intertidal portion of bays and estuaries and in many areas overlaps with commercial aquaculture.&nbsp; With continued climate change, both seagrass and aquaculture species are subjected to str...

Targeted conservation approaches seek to focus resources on areas where they can deliver the greatest benefits and are recognized as key to reducing nonpoint source nutrients from agricultural landscapes into sensitive receiving waters. Moreover, there is growing recognition of t...

Overview of published EPA wildfire research related to water quality impacts, modeling support for land management and the potential for smoke to serve as a disease vector.&nbsp;&nbsp;

In urban systems, a wide variety of processes, including increasing impervious surface cover, road salt application, sewage leaks, and weathering of the built environment, contribute to novel chemical cocktails that are made up of metals, salts, nutrients, and organic matter. Due...

Before the era of fossil fuel use, water provided power for industrial processes in the USA through a ubiquitous network of dams and mills. This infrastructure was constructed concurrently with widespread deforestation and sedimentation during the 18th through 20th centuries caus...

Seagrass beds&nbsp;play a critical role in biodiversity maintenance, serving as nursery habitats for fisheries, and aiding in carbon and sediment sequestration in the ecosystem. These habitats receive dissolved and particulate material inputs, like nutrients and heavy metals, aff...

The U.S. EPA Office of Research and Development, Regions 5, 7 and 8 and EPA Office of Water hosted a multi-regional harmful algal bloom (HABs) workshop on February 4 - 6, 2020 at the University of Kansas Edwards Campus in Overland Park, Kansas. The workshop brought together State...

This is a requested presentation from the Upper Mississippi River Basin Water Quality Task force on EPA ORD's nutrients and harmful algal bloom research in the Mississippi River Basin and Region 7. The presentation covers several research projects related to predicting harmful al...

Update on SSWR Nutrients and HABs research for Region 5 States meeting. This presentation covers research that addresses nutrient pollution and&nbsp; HABs forecasting. Where possible, we have highlighted nutrient reduction related to nonpoint sources including agriculture and sep...

Wildfire is a characteristic disturbance process affecting ecosystems of the Pacific Northwest (PNW). However, 150 years of intensive management and resource extraction across diverse PNW ecosystems complicates our understanding of how fire interacts with various ecological proce...

Targeted conservation approaches seek to focus resources on areas where they can deliver the greatest benefits and are recognized as key to reducing nonpoint source nutrients from agricultural landscapes into sensitive receiving waters. Moreover, there is growing recognition of t...

Our presentation to EPA's Region 5 Water Quality Monitoring Managers Meeting describes how we made statewide predictions of total phosphorus concentrations in Indiana rivers and streams. We outline the three datasets needed to make such predictions. The first being the Indiana De...

Wildland fires in the United States (U.S.) have increased in frequency and area burned since the mid-1980s. This trend is most pronounced in the western United States, and to a lesser extent in the nation&rsquo;s southeastern region. Historic fire suppression policies have result...

To provide recommendations for establishment of plants on a low pH mine tailings, we conducted greenhouse studies on the effects of gasified conifer softwood waste biochar (BC) plus other amendments to improve the survival and growth of plants. Experiment 1 indicated that 1% lime...

Anthropogenic impacts on lake and stream water quality are well established but have been much less studied in wetlands.&nbsp; Here we use data from the 2016 National Wetland Condition Assessment to characterize water quality and its relationship to anthropogenic pressure for inl...

Coastal eutrophication is a prevalent and increasing threat to the healthy functioning of ecosystems globally. While degraded water quality can be detected by monitoring oxygen, dissolved nutrient concentrations, chlorophyll, and algal abundance, establishing regulatory guideline...
