What our poop is telling researchers: Wastewater studied to learn if drug manufacturers are a major source for contamination of waterways

You have probably heard about researchers investigating sewer water to find out all sorts of things about the health and drug habits of the people in that town or municipality. But it appears that a lot of the pharmaceutical drugs found in wastewater are directly coming from the drug manufacturers themselves, an article on Inside […]

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 […]

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 […]

Chemists finally identify the molecule responsible for a carcinogen in recycled wastewater

Thanks to a recent study by California-based chemists, recycled water may become much safer for consumption. The researchers announced that they have tracked down the specific chemical molecule responsible for the creation of a highly potent carcinogen in treated wastewater, according to a ScienceDaily article. Formally known as N-nitrosodimethyalmine, NDMA is a cancer-causing byproduct of […]

New polymer mat able to fish biologically harmful contaminants from water

There’s a new water treatment mat that acts like a miniaturized fishing net for water pollutants. Devised by Texan researchers, it can bait, hook, and destroy toxic chemicals in water supplies, according to a ScienceDaily article. Developed by the Nanotechnology-Enabled Water Treatment (NEWT) Center, the mat uses titanium dioxide to break down pollutants. It can be made as big or […]

Tap water in Fayetteville, North Carolina tainted with carcinogen, new analysis reveals

The good news for Fayetteville, North Carolina is that there is no GenX in their public drinking water supply despite the nearby presence of the Chemours chemical plant. The bad news is that their tap water showed high levels of another cancer-causing chemical called 1,4-dioxane, an article in The Fayetteville Observer stated. The Public Works […]

Make your laundry cleaner for the environment: Researchers designing ways to treat wastewater from washing machines

You can’t see silver nanoparticles in your clothes – not even with a microscope – but rest assured these tiny particles are present in many of your underwear, towels, socks, and other garments. Ranging in diameter from 1 to 100 nanometers, they are added to give clothes anti-odor and anti-bacterial properties. In fact, a quarter […]
