Scientists believe that offshore freshened groundwater below the seafloor off the Maltese islands could provide potable water for 75 years. Offshore freshened groundwater is groundwater with salinity below that of seawater that is stored in sediments and rocks below the seafloor. However, most of this groundwater appears to be hosted in low permeability layers, making its extraction complicated and expensive.
