Using the data in Table ?, calculate what percentage of the world’s potable

water (freshwater that is fit to drink) is directly accessible in surface
reservoirs such as freshwater lakes and rivers. What will be an ideal response?


Reservoir Water volume
km3
Percent of total water
Groundwater 8,340,000 0.62
Freshwater lakes 125,000 0.0093
Inland seas 104,000 0.0078
Soil moisture 67,000 0.0050
