As humans, we have a few basic needs. Some of these being security, shelter, food, clothing, and arguably most important, water. When living in a desert though, water may not be quite so readily accessible. With recent droughts in the southwest and the already relatively scarce amount of water and rainfall in Arizona, now is the time when Arizona should begin to make itself more efficient and conservative with its water consumption, because of our reliance on the Colorado River and rapidly depleting groundwater sources and the rapidly growing population and its water demands. Arizona has an incredibly large dependence on the Colorado River and groundwater. In fact, 39% of all water usage in Arizona is comprised of Colorado River water. Any dependence of that scale on any resource that originates in another area is always a major risk, as any major disaster or drastic change to the source of the river can cripple the state’s water supply. Furthermore, while Arizona does house the majority of the Lower Basin of the Colorado, the Colorado’s Upper Basin is shared between 4 other states, all with their own water needs and all with a susceptibility to drought. On the other hand, another 40% of all water Arizona uses is from groundwater sources. However, the Colorado River and these groundwater sources in the Colorado River basins have lost over 65 cubic kilometers of water over the last 9 years, with nearly 2/3 of it from groundwater loss due to over-pumping. This is because
