Roadway runoff causes long-term sensory damage in Pacific Northwest salmon

Toxic roadway pollutants captured and conveyed by stormwater pose a serious threat to coho salmon and other fish in the Pacific Northwest’s urban watersheds. New research from Washington State University (WSU; Vancouver) shows that green infrastructure can help reduce mortality rates, but that pollutants can still potentially make fish more susceptible to predators.   Salmon’s […]

Study: To combat toxic algal blooms, focus on phosphorus

The results of an experiment spanning nearly a half-century at the International Institute for Sustainable Development (IISD; Winnipeg, Manitoba, Canada) claim that if water stewards want to stem the growth of harmful algal blooms, they should focus on phosphorus rather than nitrogen. The discovery, made by the same research organization credited with identifying phosphorus as […]

High school student wins U.S. EPA award for Portland flood mitigation study

After taking home the U.S. Environmental Protection Agency (EPA) Patrick H. Hurd Sustainability Award from the annual Intel International Science and Engineering Fair (IISEF) in May, a high school junior from Oregon will present his research at next year’s EPA National Sustainable Design Expo in Washington, D.C. Adam Nayak of Cleveland High School (Portland, Ore.) […]

WE&RF seeks research to recognize green infrastructure co-benefits

The Water Environment & Reuse Foundation (WE&RF; Alexandria, Va.) is seeking competitive proposals for research to quantify the multiple benefits of implementing green infrastructure (GI) and to evaluate its economic, environmental/ecological, and social merits at the community scale. This call for submissions is open until June 19, 2017. This project, the Framework and Tools for […]

MIT experiment reveals pathogen-spreading mechanism of rainfall

Each time a drop of rain hits the ground, small pockets of air at the surface are forced up, emitting a mist of smaller droplets in many directions as air breaks through the raindrop. Exhibiting behavior like an aerosol spray, the phenomenon could explain why freshly fallen rain leaves behind a familiar ‘earthy’ scent. After […]

Researchers seek to unlock stormwater to alleviate Texas drought

Researchers at the University of Texas at San Antonio (UTSA) received a $42,800 grant from the Greater Edwards Aquifer Alliance (San Antonio, Texas) and San Antonio River Authority to support research that would treat stormwater so that it can be used by San Antonio. According to a USTA press release, San Antonio deals with both […]

Bringing life back to dead zones

University of Illinois scientist tests bioreactors that filter nutrient runoff, reduce hypoxic zones Dead zones — those regions that can be found in the Great Lakes, Chesapeake Bay, and even the Gulf of Mexico — are a serious problem for U.S. waterways. These hypoxic zones, the result of excess nitrogen and phosphorus run off, can […]

High school students to study stormwater management at annual UMaine institute

One university has found a way to engage tomorrow’s stormwater practitioners today. More than 20 teachers and just under 100 high school students gathered at the University of Maine’s campus in Orono to try their hands at stormwater management during the final week of June. For its third consecutive year, the UMaine Stormwater Management Research […]

Hope for saving salmon lies in reducing stormwater pollution

Salmon exposed to toxic stormwater can die in a matter of hours. But preliminary new findings by Washington State University (WSU; Seattle) researchers suggest that bioretention systems, such as rain gardens, that filter out contaminants from stormwater runoff are key for preventing lethal impacts on fish, according to a WSU press release. Effective bioretention systems […]

New report predicts extreme precipitation in global dry and wet areas

A new study warns that extreme precipitation over land will increase in the world’s wettest and driest areas, with the hydrological cycle intensifying as a result of global warming. Released by Nature Climate Change, a monthly journal dedicated to publishing the most significant and cutting-edge research on the science of climate change including its impacts […]
