I want to know is there any study conducted for the impact of quantity nd quality of deep aquifers due to various deep borewells. in our area there are many aquifers at various depths. Farmers are drilling deep borewells by slotted pipes interconnecting the various aquifers. They tap water from the deep borewells as shallow wells may not yeild during lean season. The density of borewells are about 400/sq.km. My question is by these borewells will there be Any recharge to the deep aquifers from shallow aquifers during monsoon period. If there is any recharge will it help to recover the depletion of ground water. Thanks in advance
