Storms as destructive as Hurricane Harvey projected to happen more frequently

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 […]

Steel chips purge nearly 99% of E. coli bacteria from runoff in lab tests

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 […]

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 […]
