What are water springs and how they form

The springs are Natural surge of groundwater that emerge on the earth’s surface at specific points, where water flows in a way Continuous or intermittent. Its flow and discharge speed depends on various factors, such as the topography of the land, the height of the water table and the characteristics of the soil, the rock or the sediment, especially with regard to its permeability and impermeability. Generally, springs are found on hillside slopes, at the bottom of valleys or in other natural depressions, although they can also emerge under the sea, providing fresh water to coastal ecosystems.

Manantiales are formed When an aquiferfresh water reservoir, reaches its maximum capacityit overflows and Water goes to the surface. This process occurs more easily in land with geological heterogeneities that facilitate the channeling of underground flow, such as limestone or dolomite rock formations, which are more prone to fracture and allow the passage of water. The recharge of the aquifer comes mainly from rainwater and the permanence of a spring depends on factors such as the amount of rainfall and the ability of the subsoil to retain water.

Some springs only appear after intense and prolonged rainfall, while others maintain a constant flow and can release large volumes of water daily. Also, the water that crosses different types of rock can drag dissolved mineralswhich influences its chemical properties and its appearance. Thus, some springs contain sodium, carbon dioxide or iron, which gives them particular flavors and colors that can vary from bluish tones to yellow or brown.

• Biodiversity shelters constitute: Manantiales are unique ecosystems that provide stable and favorable conditions for a wide variety of aquatic species. The constant temperature and water purity create an environment conducive to the reproduction and development of various life forms. Many species of fish and amphibians have developed specific adaptations to survive exclusively in these habitats, which makes them endemic to these environments. In addition, the symbiotic relationship between aquatic and different animals is fundamental in these ecosystems; Plants offer refuge, spawning and food areas, while animals contribute to the dispersion of seeds and nutrients.
• They function as fresh water reservoirs: Manantiales represent a vital source of fresh water. Its importance is that in many regions they constitute the main source of water for human consumption and other activities such as agriculture, livestock and sanitation. When fed by rainwater infiltration, springs are part of the hydrological cycle and contribute to the recharge of rivers, lakes and wetlands. In arid or semi -arid areas, where rainfall is scarce, they can be the only available water source, which makes them essential ecosystems for the survival of various species, including human communities that depend on them.
• Regulate the hydrological cycle: The springs play a key role in the regulation of the water cycle, since they make up natural discharge points of the aquifers, helping to maintain the flow of different bodies of water such as rivers, lakes and lagoons especially in times of drought. This contributes to the stability of aquatic ecosystems and the availability of water for the realization of various anthropic activities.

Manantiales suffer from various threats due to anthropic activities and global climate change.

• Changes in temperature and rainfall patterns: They affect the recharge of aquifers, putting the continuity of the flow of water in these ecosystems at risk.
• Intensive agricultural practices: such as the excessive and excessive use of fertilizers and pesticides can contaminate aquifers and alter the quality of water that emerges in springs.
• Overexploitation of aquifers: either because of the massive extraction of water for human consumption, irrigation or industrial activities. This can reduce the flow of springs or even make them dry completely.
• Urbanization and deforestation: They alter the soil water infiltration capacity, affecting the natural recharge of aquifers and decreasing water availability in springs.
• Pollution: The discharge of industrial, domestic and agricultural waste in the vicinity of springs can compromise their purity and put the biodiversity that depends on them at risk.
• Introduction of invasive species: It has altered the stable state of these ecosystems, competing with native species, moving them and affecting the ecological dynamics of the spring.

• Villavicencio Manantial: It is a source of natural mineral water located within the Villavicencio Nature Reserve, in the province of Mendoza, Argentina.
• Wakulla Springs: It is one of the largest and most deep freshwater natural springs in the world, located in Florida, United States.
• Sant Aniol: It forms a spring with water of high purity and properties, located in the Girona region of La Garrotxa in Spain.
• White Aguas Manantial: Water outcrop located in Antofagasta, Chile.
