Groundwater flows from areas of higher elevation to lower elevation. In this figure, the direction of groundwater flow is from locations with higher numbers to locations with lower numbers. Therefore, groundwater would flow towards the right side of the figure. The only location where groundwater would flow to the left is location 4, as it is the only location with a higher number to the left of a lower number.
