Nitrogen growing threat to LI waters

Due to our septic system use, Nitrogen is building up in our Island's Aquferes and is potentially beginning to harm the water supply of Long Island. Between the Long Island Sound and our water cominginto our homes, nitrogen levels over the last 20 years have grown more than 200% and while being a nessesary component to plant life, in such high levels posses a severe threat to the plants of the long island sound.

Solar-powered system used to produce clean water in rural villages

MIT researchers have invented a new system with which they plan to help combat the "undrinkable" water problem. In villages all across the country towns people are unable to afford the costs of clean water and therefore are at risk of contracting water borne diseases such as malaria and dysentery. Thanks to their hard work, small villages will now have access to clean drinking water for less than a peso a day, more than 20 times cheaper than buying bottled water from the distributor that serves the village.
