IBM has unveiled a new nanotechnology that can both rid our water supply of toxins and desalinate salt water. IBM calls the filtering membrane a "water superhighway" because it removes toxins like arsenic from contaminated water at a greater rate as the pH level increases.
As water flows through the membrane, salts and toxins are removed so that only pure water remains when it makes it through. The membrane is also resistant to chlorine damage. This technology isn't new to IBM, just new in this application. The same chemistry and nanotech has been used in their PC semiconductor chips.
Beyond this water-scrubbing membrane, IBM also introduced a whole series of water management services to help in the measurement, monitoring and metering of water levels, contamination and usage for businesses and governments. Water quality and availability is often overlooked as we focus on other environmental issues, but it's becoming clearer that water issues need to be a priority as well. You can read about the various things IBM is doing to help here.
