Sites on opposite sides of a groundwater divide are locations between which the groundwater table separates. Based on the given figure, the groundwater table appears to flow from left to right. Therefore, sites on the left side of the figure will drain towards the left and sites on the right side will drain towards the right. Sites 1-4 appear to be on the left of the groundwater divide, while sites 5 and 6 appear to be on the right. Therefore, the only pair of sites that are on opposite sides of the groundwater divide are 4 and 5.
