    4:55 not sure if i understood you there correctly, but if we have an aquifer with low transmissivity, the cone of depression should be steep and narrow and not broad and shallow? since the water cannot move through the aquifer easily, the pumps will drain out the water close to the well with more drawdown rather than create a large cone

    Not sure if you will see this but we have a carbon capture sequestration planned for the confined Mahomet Aquifer here in illinois. Wouldn't storing co2 under an aquifer potentially cause harm to the water source??

    Is recharge rate fixed or is it dependent on the draw down? I would think that with greater draw down youd have a steeper gradient in the cone which would lead to faster recharge. With a small draw the pressure difference isnt that great and it wouldnt draw as much water in.

    It means to say find the opening of Aquifers to pull water efficiently and utilize in a Moderate Way. And, make use of Water Conservation projects to recharge Aquifers.
