Saltwater springs are often found where saltwater interacts with geological formations and groundwater streams. In these areas, groundwater dissolves and absorbs salts as it passes through salt water sources. This process is among the factors that determine the salinity level of the waters. For example, the greater the contact time and density of water with saltwater sources, the higher the water may contain salt.

The salinity level of salt water resources may vary depending on environmental factors and geological conditions. In addition, saltwater springs may contain various minerals and trace elements, which can add a characteristic taste and composition to the water.
