Highly Efficient Heavy Metal Ions Filter

Brazil experienced an unparalleled environmental disaster. When two dams broke at an iron ore mine, a poisonous cocktail of heavy metals was sent pouring into the Rio Doce, reaching the Atlantic some days later. The consequences were devastating for nature and humans alike: countless fish, birds and animals died, and a quarter of a million people were left without drinking water.

Commentary: Pavement that Protects Water

Permeable pavements allow water to filter and flow through them. They are constructed with added holes (or pores) that water seeps through to a storage area below, where pollutants are removed.

Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values.

Comparison of Bacterial Communities in Sands and Water at Beaches with Bacterial Water Quality Violations

This study supports the growing evidence that community-based molecular tools can be leveraged to identify the sources and potential impact of fecal pollution in the environment, and furthermore suggests that a more diverse bacterial community in beach sand and water may reflect a less contaminated site and better water quality.

Fire Fighting Foam may be Contaminating Water Supply

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.

Bioinspired Bifunctional Membrane for Efficient Clean Water Generation

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.

Seabin is the Innovative Water Pollution Solution for Marinas, Docks and Yacht Clubs

A pair of Australians have launched an Indiegogo campaign for an automated marina rubbish collector dubbed Seabin. The device, which addresses the issue of ocean pollution on an introductory scale, is so deceptively simple yet ingenious that it makes you wonder why it hasn’t been created until now.

Shaking the Nanomaterials Out: New Method to Purify Water

The method sounds like a salad dressing recipe: take water, sprinkle in nanomaterials, add oil and shake.

Old Gasoline Leak Puts Mora City Water at Risk; MPCA Rests Cleanup Technology

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.

Water Problems Need Local Solutions: New Book

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.”

Bottled, Boiled or Filtered Water: How to Get Pure Drinking Water in India?

In many places, you can’t drink tap water in India directly and safe or pure drinking water is a big concern for most of us. Every year 37.7 million people in India are affected by waterborne diseases due to contamination of water by bacteria (E coli, Shigella, Vibrio cholerae), viruses (Hepatitis A, polio virus, rota virus) and parasites (E. histolytica, Giardia, hook worm). Luckily, antibiotics and other medicine can treat most water-borne diseases. What is more worrying is the presence of arsenic and other heavy metals such as cadmium, zinc and mercury.
