I still see this type of calculations and reasonings so often, but I think this is dangerous and leads to very unsustainable #groundwater usage and different undesirable effects in many parts of the world.
In this thread, I explain why (1/4). https://twitter.com/IndHydrogeology/status/1345492722031869952

Pumping groundwater always has effects on other fluxes in the basin.
Groundwater is feeding rivers, lakes, wetlands and groundwater dependent vegetation. If you pump out an amount close to recharge, rivers, wetlands and vegetation dry out(2/4). https://doi.org/10.1016/S0022-1694(00)00263-8

Lowering groundwater levels/hydraulic head because of groundwater pumping may also result in other adverse effects: land subsidence, saline groundwater and lower groundwater quality (3/4). https://www.theguardian.com/world/2020/dec/31/land-subsidence-will-affect-almost-fifth-of-global-population
Does that mean we can't use groundwater?
No, groundwater can play an essential role in development, but in order to determine sustainable groundwater rates, we must understand all long-term effects on fluxes and groundwater levels. (4/4) https://doi.org/10.1016/j.jhydrol.2009.03.009
