"From 2009 to 2012, water production from one well on his ranch fell by two-thirds, a problem Mr. Fitzsimons linked to nearby wells pumping water for fracking operations. A study commissioned by his groundwater district found that in a five-county area that includes Dimmit, fracking reduces the amount of water in the Carrizo-Wilcox Aquifer by the equivalent of one-third of the aquifer’s recharge. Recharge means the amount of water an aquifer regains from precipitation and other factors." (Quoted from article)
