Although perhaps the greatest public health achievement of the 20th century was the disinfection of water, a recent study now shows that the chemicals used to purify the water we drink and use in swimming pools react with organic material in the water yielding toxic consequences.
A study out from the American Chemical Society says you should run your water for a while before using it – which goes against everything people say about wasting water – and they blame all the reduced-flush toilets, low-flow showerheads and other water-saving green technologies that’s making our water “stale” while it sits in our pipes.
Getting access to drinking water is a daily challenge for more than one billion people in the world. Desalination may help relieve such water-stressed populations by filtering salt from abundant seawater, and there are more than 7,000 desalination plants worldwide, 250 operating in the United States alone. However, the membranes that these plants use to filter out salt tend to break down when exposed to an essential ingredient in the process: chlorine.
