According to experts in the failure of oil and gas pipelines, there are a handful of factors that can contribute to a pipeline rupture, like the one in Mayflower, Arkansas. A new report finds all were in play on the Pegasus pipeline.

More than six months since tar sands oil spilled into a Mayflower, Arkansas neighborhood, two homes have just been leveled by Exxon in order to clean up oil that was found under their foundations.

After two years of pressing pipeline regulators to release inspection photos and videos of the 60-year-old Enbridge pipeline that carries tar sands oil through the Straits of Mackinac, NWF took it upon themselves to inspect the pipeline.

The UK government has approved a new scheme for desalination of water from the Thames, for use in London. The £200 million plant will be built in Beckton, east London. It's not a popular plan, though, among environmental campaigners. We've written before

We´ve noted in the past plans for new desalination plants in Australia and low-grade energy desalination technology from New Mexico.

Record droughts, falling water tables and the rapid depletion of aquifers have helped make desalination, a process once considered impractical and too expensive, a viable technology -- at least in some places. As such, there has been a rash of stories --
