What is one of the consequences of the intrusion of seawater into groundwater basins?

• A. Reduced water clarity
• B. Overpumping
• C. Increased mineral content
• D. Enhanced water taste

Answer: (B)

One of the primary consequences of seawater intrusion into groundwater basins is the increased mineral content of the groundwater. When seawater mixes with freshwater in aquifers, the saline water introduces a higher concentration of dissolved salts and minerals, dramatically altering the water quality. This increase in mineral content can lead to various problems, such as making the water unsuitable for drinking and agricultural purposes due to the high salinity levels. In contrast, while overpumping groundwater can indeed result in various issues such as the lowering of the water table and the potential for seawater intrusion, it is not the direct consequence of seawater intrusion itself. Instead, the intrusion is predominantly characterized by the changes in water composition, particularly an increase in mineral content, which directly impacts usability and sustainability of the water resource.
