A new Insurance Bureau of Canada (IBC; Toronto, Ontario) report urges communities to consider green infrastructure to limit flood risk. IBC is the national industry association representing Canada’s private home, auto, and business insurers. Its member companies make up 90% of the property and casualty insurance market in Canada. The report, Combatting Canada’s Rising Flood […]
When Hurricane Harvey inundated eastern Texas late last August, the eye of the storm loitered over land for nearly a week rather than dispersing as it moved farther from the ocean, as most hurricanes do. The result was a stronger, more destructive storm, which dropped a record-breaking 127 cm (50 in.) of rain and directly […]
In the watershed of the Big Sioux River, a 675-km-long (420-mi-long) tributary of the Mississippi, the South Dakota Department of Environment and Natural Resources reports that nearly all streams exceed regulatory limits for Escherichia coli bacteria. After a summer storm, runoff drives E. coli levels in some streams to reach as high as 2000 colony-forming […]
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 […]
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 […]
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.) […]
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 […]
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 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 […]
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 […]
