Phoenix Is Slowly Sinking

Phoenix Is Slowly Sinking (Source newser.com) Researchers say that while there’s no need for residents of Phoenix to panic, parts of their city are slowly and unstoppably sinking into the ground. Land subsidence caused by the extraction of huge quantities of groundwater over the decades is to blame, and the Arizona State University researchers say it’s causing some parts of the metropolitan area to sink by roughly 0.75 inches a year, Sonoran News reports. Residents may not notice much change year to year, the researchers say, but over time, the problem will affect things like canals, utility lines, and sewers and, eventually, the foundations of buildings. The depletion of groundwater has changed the sediment under the area, so the drop is irreversible.
