Many of the rapidly growing Phoenix suburbs are projected to find themselves in trouble with regards to water resources in the future. These suburbs have met their 100+ years of water requirement using the Central Arizona Groundwater Replenishment District (CAGRD), an entity created in the 1990s tasked with replacing pumped groundwater by finding renewable water supplies and injecting that water back into the aquifer.

However, the current drought and temperature projections going forward show that it will be increasingly difficult for CAGRD to find water to inject back into the aquifer to meet its obligations. In the end these suburbs will either need to pay super high rates for water to inject into aquifers or will need to slow growth.

Thanks for this -- it's critical to recognize that the supply for the groundwater replenishment upon which much of the "100+ year" assured water contingency rests is provided in part by the Colorado River.
