New technologies in public water fountains let people refill bottles with clean, commercially filtered H20. The touchless fountains are also healthier, since they are hands-free. Whether you’re traveling or just on the go, the free app WeTap (available for iPhones) helps you find public water fountains wherever you are. Enter where you are, and the app will point out refill stations near you. You can update the app, too, to help others find hydration stations in parks, stadiums, schools and more.

Many beverages like milk, soy milk, wine and even water come packaged in paperboard containers called Tetra Paks. These paper containers are made of several layers of paperboard, aluminum and other recyclables, and they used to be hard to recycle. Now, many communities accept them for recycling, which is great news. When recycling Tetra Paks, you can leave the plastic caps on; they are recyclable. And don’t flatten them too much since recycling sorting machines recognize these materials by their 3-D shape.

If you run or go for long-distance walks, you can turn your workout into a fundraiser for the charity of your choice. The app CharityMiles tracks how many miles you run or walk in a workout. Corporate sponsors give money to charities based on the number of miles you (and other members) worked out. Over 40 million miles have been logged and more than $2 million has been given to charities like the World Wildlife Fund and Habitat for Humanity. Learn more at charitymiles.org.
