Saline groundwater in the Canary Islands (Spain) resulting from aridity

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. -from Author
