Fluid Pressure: Saltwater Well

CLMECH-J9ZZYX

You are digging a well in the ground when it fills with saltwater (density $\rho = 1030\space kg/m^3$). You decide to use a vacuum pump to pump the water out of the hole.

To what maximum depth of well (in meters) will your pump be effective if the atmospheric pressure is $1.01\times 10^5\space Pa$?
