In fact, there is a over a thousand times more water in the ground than is in all the world's rivers and lakes. Here we introduce you to the basics about groundwater. • Water Science School HOME • Groundwater topics •between aquifers so it might be more precisely termed “aquifer-system” or “saturated-zone” recharge. This def-inition avoids double-accounting in large-scale studies. Recharge is commonly expressed as a volume [L3], typ-ical units being m3 or acre-ft. Recharge rate expresses either a flux [L3T−1] into a specified portion of aquifer,
