Re: the Nov. 17 article "Groundwater levels falling amid strong suburb growth."
My parents' 20-acre property just east of the Tucson National golf course had a private well. It ran dry shortly before we moved there in 1981 so we had it drilled 150 deeper. In 1996 it ran dry again. The math is simple: 150 feet in 15 years averages ten feet per year.
