We aim to create a collaborative environment in which progress towards understanding and addressing the increasing demands and scarcity of freshwater can be made in the 21st century. To help visualize and gain a more in-depth look at what we are working on, Columbia Water Center has released an updated research projects section of its website.]]></description>

		<description><![CDATA[Hydraulic fracturing is a technique used by the oil and gas industry to facilitate natural gas recovery in underground low permeability coalbed methane wells. This operation improves the extraction efficiency of methane by creating fissions or fractures in underground rock formations, generally 5,000 – 20,000 feet below the ground surface. Highly pressurized hydraulic fracturing fluids, [<a href="http://blogs.ei.columbia.edu/2010/05/03/hydraulic-fracturing-potential-for-contamination-of-drinking-water-sources/">...</a>]]]></description>

There may be no bigger an issue when taking into account the three aspects of sustainable development than the issue of global water scarcity and the growing gap between water supply and demand.
