Groundwater: Freshwater or Salty water?
Groundwater is typically considered fresh water because it originates from precipitation that infiltrates the soil and percolates down to the groundwater table. This water is usually free from salts and other contaminants, making it safe for human consumption and agricultural use.
However, during cyclones or storms, seawater from the ocean can be pushed inland, causing flooding in coastal areas. When this salty water mixes with the freshwater in the ground, it can contaminate the groundwater with salt. This process is known as saltwater intrusion.

Why is Groundwater still considered Freshwater?
Despite the potential for saltwater intrusion during cyclones or storms, groundwater is still generally referred to as fresh water. This is because the natural movement of freshwater through the ground helps to dilute and flush out the saltwater intrusion over time.
Additionally, in regions where saltwater intrusion is a concern, steps can be taken to prevent or mitigate the effects. For example, barriers can be installed to prevent saltwater from infiltrating groundwater sources, or alternative freshwater sources can be developed to meet the community's needs.
Overall, while groundwater may temporarily become contaminated with salt during extreme weather events, it is still classified as fresh water due to its natural composition and the ability to manage and mitigate saltwater intrusion.
