Imagine you have a layer of limestone with high porosity but low permeability.What can you do to increase its permeability to allow water to be pumped from the layer and used as a source of drinking water?
A)Add acid to the layer to dissolve the rock and create connections between the pores.
B)Drill down to the layer and set off explosives in the hole to fracture the rock.
C)Remove the overburden so that there will be less pressure trapping the water.
D)Increase the hydraulic conductivity by adding metals to the water.

Question

The best choice to increase permeability in this situation is to fracture the rock using explosives, which will create interconnected pathways for water to flow through the porous rock. Adding acid or metals to the water may cause contamination and is not a suitable solution. Removing the overburden might reduce pressure but will not necessarily increase permeability.
