Open-Access WER Article Examines Effectiveness of Man-Made Wetlands

The April 2015 issue of Water Environment Research (WER) includes an open-access article investigating the effectiveness of a man-made wetland system, consisting of linked basins, in local flood control and contaminant filtration. According to WER Editor-in-Chief Tim Ellis, “the authors used a combination of field and lab experiments to characterize the retention and removal of iron, phosphate, and […]

USGS Releases Studies on Hydrologic Characteristics of LID and Coal-Tar Sealants

Earlier this year, the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency’s (EPA) Office of Research and Development released a report examining the hydrologic characteristics of low impact development (LID) stormwater control measures at two sites in northeastern Ohio. Limited long-term performance data exist for LID systems as stormwater controls. The purpose of […]

WERF Requests Research Proposals on Reclaimed Water and Stormwater Harvesting

The Water Environment Research Foundation (WERF) is seeking proposals for research to overcome pricing and economic barriers to using alternative water sources. Proposals for this project, Economic Pathways and Partners for Use of Reclaimed Water and Harvesting Stormwater, are due no later than May 13. The proposals should take research to the next level of […]

Reduced Narcotics Possession Found Near Philadelphia Green Infrastructure

The benefits of replacing outdated and overwhelmed urban sanitary and storm sewer systems with green stormwater infrastructure may extend far beyond water quality. New research by U.S. Forest Service scientists and partners found reduced narcotics possession occurring within a half-mile of Philadelphia’s new green stormwater infrastructure projects. The article, “The impact of green stormwater infrastructure […]

Isolated Wetlands Essential for Clean Water, Study Says

Geographically isolated wetlands play a large role in providing clean water and other environmental benefits even though they may lack the regulatory protections of other wetlands, according to an article by Indiana University (IU) researchers and colleagues. Citing research literature, the article, “Geographically Isolated Wetlands Are Important Biogeochemical Reactors on the Landscape,” says geographically isolated […]

Rainwater Harvesting Provides Clean Water Access in Ghana

Researchers from SINTEF, Scandinavia’s largest independent research group, are using rainwater harvesting to provide sustainable access to clean water in Ghana. While the country has both surface water and groundwater resources, infrastructure for treating and distributing that water is underdeveloped. The country faces many infrastructure challenges, including climate change, and while total rainfall in Ghana […]

University Releases Great Lakes Coastal Wetlands Map

The Michigan Tech Research Institute has developed a comprehensive map of the Great Lakes coastal wetlands. This map is available publicly and is the first of its kind on such a broad scale. It shows more than 16,000 km of shoreline across the entire basin in both Canada and the U.S. The map can help […]

New Reports Highlight Opportunities During Green Infrastructure Implementation

Although green infrastructure is a critical tool for solving stormwater management challenges, it includes a set of evolving technologies “with inconsistent performance and uncertain costs,” according to a new report, released in March, by the UC-Berkeley School of Law Center for Law, Energy & the Environment. Uncertainty about the performance or life-cycle costs of green […]

Soil Media Protects Salmon from Runoff Toxics

Soil media can reverse the toxic effects of urban runoff that otherwise quickly kills young coho salmon and their insect prey, according to new research by Washington State University, NOAA Fisheries, and the U.S. Fish and Wildlife Service. Polluted stormwater has been identified as a risk factor for many threatened and endangered salmon and steelhead […]

New Study Quantifies Amount of Plastic in World Oceans

On Dec. 10, 5 Gyres Institute published a new report in the journal PLOS ONE that is the first global estimate of plastic pollution — both micro- and macroplastic. The study culminates over six years and 50,000 nautical miles of pelagic plastics research, the most comprehensive study of its kind to date, according to the […]
