yes and no...the total amount of water is constant this is completely true...but the amount of clean and available ground water is not...
the more you pump the more you "plug" the ground...lets take herbicides completely out of the picture and just focus on the effect of pumping mineral rich water, the minerals sediment in the ground and form a layer or plug...this never goes away ever...
when hanibal invaded the roman empire, the romans went to tunis (where hanibal is from) and pumped sea water all over their fertile fields and to this day, 2000 years later, the ground is still infertile...
ok sea water has tons more minerals than normal ground water but they pumped for just a few days, you get a good picture of what constant watering does to the ground...
now lets put herbicides in to the picture and fertilizers, lets take in to account that plants do not want to grow on desert sand but need nutrients...
in short: you guys will be fine for the next 50 years...but dont plan on having a golf course or anything green growing there for the next 1000 years after that...I guess you can play golf on astroturf
I own commercial greenhouses I know a bit about this ect...
