The Minnesota Department of Transportation (MnDOT) is exploring innovative ways to filter pollutants from stormwater runoff and meet permit requirements for construction projects. In a recent study, U of M researchers documented the performance of an iron-enhanced ditch check filter to remove phosphates from stormwater. They found that the filter was effective, though its performance decreased over time.
DENVER — A multibillion-dollar reservoir and pipeline project may one day pull more than 50,000 acre-feet of water per year from the South Platte River before it reaches Nebraska. That’s more than 16 billion gallons of water, enough to fill 25,000 Olympic-sized swimming pools.
The safety and health of all those who work in construction remains the top priority for the National Association of Home Builders (NAHB). The industry continues to adhere to all public health guidelines set forth by OSHA and the CDC. Work on a new unfinished home site occurs primarily outdoors and does not involve going onto a location occupied by residents or a public location, and there is minimal (if any) physical or transactional contact with customers.
In southern Italy, the pristinely preserved remains of the ancient Roman city of Pompeii have mystified historians and archaeologists since they were rediscovered nearly 300 years ago. Ongoing expeditions continue to reveal new details about the city and its people, believed to have been decimated by the sudden eruption of nearby Mount Vesuvius around 79 CE.
MARBLE — The U.S. Army Corps of Engineers has determined that the operators of a local marble quarry violated the Clean Water Act when they diverted a tributary of the Crystal River to make way for a mining road.
Researchers at Colorado State University, Kent State University, and UCLA are working on a joint project to study stormwater and green infrastructure decision-making in Denver and Cleveland. We are seeking stakeholders who work in stormwater management and green infrastructure in the Denver region (in private industry, government, and nonprofits) that would be interested in taking a brief (15 min) online survey about their experiences in stormwater planning and compliance.
Mile High Flood District is ready to start their new bioretention study. They are looking for bioretention basins throughout the District that have been in place at least a year. It can be one you think is a good example or one with which you are struggling. Please use the link below and fill out what you can. MHFD can help sort through design documents and look at the site to fill in the blanks.
The U.S. National Oceanic and Atmospheric Administration (NOAA) predicts the Gulf of Mexico’s annual summer dead zone – a low-oxygen area which can cause mass death of marine life – will grow over 40% this year compared to last summer, approaching the size of Massachusetts.
The effects of this year’s dead zone on the local economy already are becoming apparent. According to Nancy Rabalais, a Louisiana State University (Baton Rouge) marine ecologist and expert on the Gulf dead zone, fishing has slowed to a crawl in the region.
