Clean Water

“What have I got in my pocket?" he said aloud. He was talking to himself, but Gollum thought it was a riddle, and he was frightfully upset.
"Not fair! not fair!" he hissed. "It isn't fair, my precious, is it, to ask us what it's got in its nassty little pocketsess?” - The Hobbit by J.R.R. Tolkien On the subject of The Ripple Effect, the second point seems most important to us, as a country, right now: that we can pollute water beyond our ability to clean it. One way that we do this, which has been in the news lately, is with the process known as “fracking,” which is used to obtain natural gas from the earth. In order to perform hydraulic fracturing, vast amounts of water are injected into the ground, along with some potent chemicals. The chemicals seem to pollute not only the injected water, but, more importantly, the groundwater in the area. We have not yet come up with a satisfactory way to filter out most of these chemicals and make the water safe for use again. Another way, related to the energy industry, that we pollute water is, of course, with all the oil spills that we have. It’s true that we constantly hear about terrible oil spills in the ocean, but there are also leaks in the pipelines that stretch across groundwater throughout the country. The Keystone Pipeline -- the several thousand miles of pipes that will bring oil from its source in the oil sands of Alberta,Canada down to the Gulf of Mexico -- is yet another concern: will that be properly maintained and protected, or will it spill out and threaten the groundwater of the entire midsection of the country? We cannot destroy water with our chemicals. But we can ruin vast quantities of it so that it cannot be re-used -- at least not until we come up with a good way to clean it. Many chemicals can be removed from water by our current methods. Different types of filtration and water softening techniques can remove much in the way of bacteria, some viruses, and even some chemicals like magnesium and phosphorus. There are even some recently-devised “natural” ways of removing chemicals, such as an algae system invented by a high school kid, which, among other contaminants, has the ability to remove silver particles and collect them. But the key word is particles. The bigger the molecules are - and bacteria are pretty huge compared to dissolved chemicals - the easier they are to remove. Environmental engineering companies like the Blacksmith Institute have shown some promise, but we need to develop a comprehensive water purification system that would remove all contaminating chemicals, no matter what they are. That would actually change the current trajectory of our environment.
