Perfluorooctanoic acid (PFOA) is a chemical that most people have probably never heard of. However, it is more common than we realize and can be potentially harmful to humans, animals, and the environment. The EPA categorizes it as an “emerging contaminant,” meaning it is a chemical that poses a potential or real threat to human health or the environment.
Solving the problems of water pollution and water shortage is an urgent need for the sustainable development of modern society. Different approaches, including distillation, filtration, and photocatalytic degradation, have been developed for the purification of contaminated water and the generation of clean water. This study explored a new approach that uses solar light for both water purification and clean water generation.
The method sounds like a salad dressing recipe: take water, sprinkle in nanomaterials, add oil and shake.
The Minnesota Pollution Control Agency (MPCA) will test petroleum cleanup technologies at the former Town & Country Oil site in Mora in an effort to continue preventing contaminants from migrating to nearby city water wells. Gasoline and diesel fuel leaked into the ground at the site, located at the southwest corner of Maple Avenue and Highway 65, some 15 years ago.
Rather than seeing the world’s water problem as one global crisis, author and journalist Marq de Villiers prefers to break it down and suggests there are solutions best taken up locally. His view is outlined in a new book called “Back to the Well: Rethinking the Future of Water.”
What makes Ron Manuel’s driveway so special? It’s made out of permeable concrete. When it rains, the water drains right through it and into the soil below.
CORPUS CHRISTI – City crews are making progress installing backflow preventers in Flour Bluff. Those devices are being installed in homes with wells to prevent an E-Coli scare like the one we had a couple of months ago.
Water technology and monitoring company Modern Water has launched a range of oil in water monitoring products in the US and has supplied a Multisensor 1200 volatile organic compound (VOC) monitor to Glendive Water Treatment Plant in Montana to ensure safe drinking water for around 6,000 people.
California’s coastal border with Baja region is particularly vulnerable to rains. Storms send muck and sewage down canyons, into channels, and finally gets discharged into the Tijuana River and the Pacific Ocean, prompting pollution warnings and beach closures in both countries. Contamination and cross-border pollution has been a fraught topic for years, but never more so than now, ahead of a rainy season in which a historically powerful El Niño appears imminent.
A group of students from the Technical University of Denmark have created a sensor that they say can detect bacteria in water instantly, on the spot. Developed through spin-off company SBT Aqua, the sensor utilizes a technique known as impedance flow cytometry.
Swim areas in Lake Isabella do not have high levels of E. coli, but village officials are working to find the source of the bacteria that is found in many water sources in mid-Michigan. Village officials have been working for two years with the Central Michigan District Health Department to monitor E. coli in the man-made lake that was a section of the Chippewa River before a dam was built.
