Since the recharge area is on the left side of the fault, the water is not coming from the right side. Therefore, rock unit A on the right side must have low permeability, meaning that water cannot easily flow through it. This is supported by the fact that springs are located along the surface trace of the fault, indicating that the fault is acting as a pathway for water to flow through the low permeability rock.
