  • Will the Fortune 100 Save Us?

    Environmentalists have long criticized our corporate behemoths for environmental violations and unsustainable business practices. Walmart, GE, Coca-Cola were once considered toxic to the environment and not the names that came to mind for a green future. However, environmentally-friendly announcements over the past few years have challenged this perception.

  • Fix a Leak Week, March 16-20, 2009

    New York’s Department of Environmental Protection is sponsoring Fix a Leak Week this week throughout the city. In addition to the free water-saving kits (mentioned below in Samantha’s post), the city seems to be actively tackling the issue of water preservation.

  • IBM’s Water Membrane

    Scientists at IBM Research, together with collaborators from Central Glass, KACST and the University of Texas, Austin have created a new membrane that filters out salts as well as potentially harmful toxins in water such as arsenic while using less energy than other forms of water purification. According to the press release, this materials in…

  • Water for Profit?

    I’ve long been fascinated by the concept of privatization of water.  I can think of few topics related to natural resources that are so controversial.  I tend to reject the claim, espoused by many including former Water Center speaker Maude Barlow, that water is a basic human right and therefore should never be private.  While water…

  • Water Usage Per Person

    Seeing Samantha’s post on water conservation kits reminded me how much water we use in the US compared to others in the world. The above data is from UNDP Human Development Report 2006. For your reference, 1 liter = 0.264172052 US gallons. I hope there are a lot of related posts that come from this…

  • Free water saving kits from NYC DEP

    If you go to the New York City Department of Environmental Protection website, you’ll see that nearly half the items on the homepage are about water. There’s the large scale, like protecting and maintaining the sewer systems and watersheds, and also the smaller scale, such as their rain barrel and residential water conservation programs. As…

  • Sand Filtration

    Via ScienceDaily, Dr. James Amburgey, from the University of North Carolina at Charlotte, has developed an inexpensive and low-tech way to treat water using sand.  According to Dr. Amburgey, all that is needed to create safe drinking water is PVC pipe, sand and inexpensive treatment chemicals. Previous technologies have used sand filtration, however, this current…

  • LifeStraw®

    According to the World Health Organization, 3.575 million people die each year from water-related disease, and 84% of water-related deaths are in children ages 0 – 14. Access to safe and clean water is an option many people in developing countries don’t have. I think the picture above says all that is needed about the LifeStraw®,…
