Abstract
Groundwater recharge in arid lands is only a very small fraction of rainfall, its salinity is high due to the concentration of rain-contributed and airborne salts by evapotranspiration in the upper layer of the ground. This is enhanced in windy coastal areas and islands due to the important contribution of airborne marine salts. There brackish to salty groundwater is commonly found. Examples from the Canary Islands are presented and discussed, and possible explanations are outlined. Local solutions for water supply are briefly presented.
