SHOCKING study reveals that tap water contains a class of harmful, toxic insecticides
Anyone living near the Iowa River should be wary of their supposedly “safe” tap water. A study released by local researchers warned that some sources of treated water in the area have been contaminated with dangerous insecticides, an article in Natural Health 365 stated. The pesticides in question are three types of neonicotinoids, a class […]

Useful way to repurpose invasive weeds: Water hyacinth, an invasive plant to river ecosystems, may prove useful for oil sorption
Those thick clumps of water hyacinth clogging our waterways might be useful for something, after all. A Thai study suggested that the invasive floating plant can be turned into biodegradable adsorption materials that can clean up oil spills better than polypropylene-based sorbents. The findings were published in the International Organization of Scientific Research. Polypropylene is a […]

Dangerous, toxic, potentially catastrophic: Tailing ponds for copper mine quietly being planned upstream from the St. Louis River, Lake Superior
A Global Research article drew attention to the quiet plans of a foreign corporation to set up insufficiently secure toxic tailing ponds for its copper mine sited upstream of the vital St. Louis River in Minnesota. According to the article, PolyMet Mining is planning to set up an “enormously dangerous [and] potentially catastrophic” lagoon that will store […]

Engineers devise a system that recovers fresh water from power plants
What do you think of an electrical power plant that can also provide an inexpensive source of drinking water? Engineers have come up with a way to recover the water used to cool power plants and purify it for human consumption, an article in Science Direct stated. Nearly 40 percent of the water drawn from freshwater sources […]

Old biological filters work better than new water treatments, according to Swedish study
An old water treatment technology called slow sand filters could be making a comeback – and the older filters would work better than both newer ones or modern filtration methods. According to Science Daily, a Swedish study suggests that the older the filter, the better it is for treating water. Slow sand filters first appeared during […]

Sunlight triggers chemical reactions that make the Deepwater Horizon oil spill unlikely to degrade
Eight years have passed since the Deepwater Horizon disaster of 2010. But oil continues to persist in the waters of the Gulf of Mexico. A study warned that this water pollution is caused by chemical reactions in the oil due to exposure to sunlight, an article on Science News reported. The disaster was the biggest marine oil spill […]

Cities that are running out of water can now safely remove at least some pharmaceuticals from recycled water and wastewater
If cities are forced to recycle water, they’ll need to find a way to filter out pharmaceuticals – such as the widely used anxiety drug Diazepam – from wastewater. So, South African researchers have developed titanium dioxide nanofibers that can remove drugs from water, reported ScienceDaily. The fibers are the brainchild of a research team […]

Some toxic chemicals found in water can be created by the treatment process itself
Water treatment processes are supposed to make public water safe enough to wash or even drink. However, some of the newer methods that break down harmful substances apparently create new toxic chemicals that are just as bad, an article in Science Daily states. Most water treatment plants use oxidation-based processes. These treatment methods break down […]

U.K. scientists call on public to help track and map plastic pollution on local beaches
Britain’s coastlines are so polluted with plastics that researchers have turned to the public for assistance. An online interactive map of the U.K. will allow anyone to identify and map plastic garbage found on local beaches, reported The Guardian. Researchers from the British Science Association (BSA) cooperated with members of the charity The Plastic Tide […]

Engineers study self-assembling block polymer membranes as an alternative option for water treatment
As water scarcity spreads across the face of the Earth, researchers are scrambling for ways to convert non-traditional sources into potable water. In a Nano Werk article, engineering researchers from two universities reported that self-assembling block polymer membranes could be used as alternative materials in water filtration. The United Nations warned that about 1.9 billion […]
