Newly public predictions about potential source water contamination are casting doubt on models used to anticipate how polluted water may flow from mining operations. The problem centers in Minnesota, where a proposal for the state’s first copper-nickel mine has remained under environmental review for a decade.
Keeping contaminants out of the Dan River in North Carolina — while being ready to quickly treat any that might appear — was the goal of an exhaustive study recently completed for the Danville Utilities water plant.
Two years ago in September the Global Water Center celebrated its grand opening, and since then the facility has attracted new businesses, corporations and startups, not to mention a handful of universities too — all of them with the same focus: water technology.
The Zimba batch chlorinator, one of the inventions recently recognized in the Innovation Countdown 2030 compiled by public health and innovation nonprofit PATH, could provide developing countries with clean water in a package smaller than a bedside nightstand.
Karen and Scott Reynolds, both dog trainers, started their business in 2009 in Lansing. Scott Reynolds also worked as an environmental scientist at the time, and often was tasked with tedious, time-consuming storm water testing for bacteria such as E. coli, which is derived from human waste and can seriously sicken people when they contact or drink it at certain concentrations. It was Scott’s boss who suggested they train a dog to sniff out human waste in rivers, streams or other water, Karen Reynolds said.
In a drought that seems to have no immediate end in sight, one California municipal water agency literally rolled out a unique solution to protect the valuable commodity in its water storage facilities. Thousands of black plastic “shade balls,” released Monday, Aug. 10, by the Los Angeles Department of Water and Power (LADWP), are the only things that stand between the water in Sylmar, Calif.’s Van Norman Reservoir and damaging environmental exposures.
A book with pages that can be used to filter murky drinking water has seen success in its first field trials. The so-called “drinkable book” features treated paper which can be torn out and used to kill bacteria in water, as well as printed information on the importance of filtering drinking water.
Dry brown grass is part of the fallout from any Texas summer, but getting a lush green landscape might not take as much effort as many think, with the help of a tool which tackles water waste.
Scientists in Canada is developing a fascinating way to sense when water is contaminated. Their box, called the FRED or Field Ready Electrochemical Detector, contains “tunable” bacteria that react in the presence of unwanted substances.
The Nebraska Oil and Gas Conservation Commission has only eight employees, but this little state agency has some big responsibilities — like keeping waste water from oil wells from polluting drinking water, and evaluating whether that waste water could cause earthquakes.
How much energy do water and wastewater companies use to treat and distribute water? Thus far, the issue has been relatively undocumented, according to the American Council for an Energy-Efficient Economy (ACEEE). But the ACEEE and the National Association of Water Companies (NAWC) recently conducted a survey to find out.
Wastewater plants must invest in better treatment technology to prevent painkillers and cocaine from entering the water supply, according to a leading researcher.
