Surface water and groundwater resources
The long-term average internal renewable water resources (IRWR) are estimated at about 700 million m3/year (Table 2 and Table 3).
Freshwater resources are finite and vulnerable in The Bahamas. Fresh surface water is basically non-existent. There are no true rivers or streams on the islands due to the low relief of the country and to the high permeability of the limestone surface that permits the rainwater to percolate quickly to the water table. Thus, freshwater resources in the country are limited to very fragile freshwater 'lenses' in the shallow karstic limestone aquifers (USACE, 2004).
Inland water bodies are usually places where the water table is at or near the same level as the land surface. These bodies are usually saline or brackish nature. In some cases, ponding of water can occur after a heavy rainfall where the surface rock retards infiltration.
In 2000, total desalinated water produced was estimated at 7.4 million m3.
