Description

<p>Submarine groundwater discharge (SGD) is thought to be distributed all over the world, especially in volcanic regions and limestone areas. The volume of discharged groundwater amounts to 40 % of total river discharge, recent studies indicate, and its quality is like that of pure groundwater. Lack of drinking and industrial water is a worldwide (including Japan) serious problem, and it is necessary to initiate studies concerning the development of new water resources, like SGD, which prevents a problem such as saline groundwater and subsidence by excess of groundwater use from arising. As the result of choices based on the consideration of cost, technology and performance, it is proposed that we use deep groundwater as a new way of opening up water resources, but research is needed because SGD is located at the end of the continental groundwater flow system and gives us reliable data of waste rate of groundwater.</p>
