By research, hydrogeologists found that volcanic mountain springs fulfill the three conditions of groundwater quality characteristics, namely quality, quantity, and continuity. Quantity is influenced by rainfall, water cycle and hydrogeological conditions of the area around the water resources. Quality is influenced by natural factors (conditions and composition of soil and rocks) as well as human activities (agriculture, household pollution, industry, etc.). While continuity gives a balance between usage and recharging.
Groundwater starts from a hydrological cycle, where clouds are composed of millions of tiny drops of water, so light that these droplets can float in the air, then lifted up by the warm air flow from the ground and eventually turn into rainwater that falls to the earth. The water permeates and is deposited beneath the soil surface, which is then due to the effect of gravitational forces moving vertically through the soil layer until it reaches the water saturated zone and is finally deposited in a layer of water-carrying rock called an aquifer.
Based on the constituent material and its physical environment, there are several types of aquifers, namely allifial fan aquifers (located in coastal areas, sedimentary and surrounding areas), sedimentary aquifers (peat, organic), karstic aquifers (limestone mountains) and volcanic aquifers volcanoes), which is the best source of fresh water. Aquifers are layers or rock formations capable of storing and passing water in significant quantities, capable of providing supplies to wells or springs. Indonesia is a wet tropical region with relatively high rainfall and geologically located in the volcanic arc area. Indonesia has more than a hundred active and inactive volcanoes. Geologically the volcanoes form rock layers that are very conducive to acting as aquifers.
During the drainage, groundwater undergoes various processes that make the groundwater contain a variety of minerals and ultimately have different qualities in each place. As a continuation of natural processes, groundwater then appears on the surface and is called a spring. In this case, the springs in the mountains are regarded as the perfect source of water, both quantity and quality. Mountain springs in the mountains are generally large and continuous because in this area is generally a wet area with high rainfall intensity and still has a relatively good catchment area.Cyclus of water in nature (Source: http://kimlingiwill.blogspot.com/2010/11/pegunungan-vulkanik-sumber-mata-air.)
Springs conservation is needed for human survival. Because humans really need clean water to stay alive and healthy. Springs conservation must be done immediately and cannot be delayed anymore. not only humans who need water, but all living things that exist today and in the future all need it. Water is a substance or matter or element that is important to all life forms that are known to date on earth.
The Facts to remember
- The human body consists of 55% to 78% water, depending on the size of the body.
- In order to function properly, the human body needs between one and seven liters of water daily to avoid dehydration (the exact amount depends on the level of activity, temperature, humidity, and several other factors).
- Most people believe that humans need 8-10 glasses (about two liters) per day.
- But the results of research published in the University of Pennsylvania in 2008 showed that the consumption of a number of 8 glasses is not proven to help a lot in nourishing the body.
- In fact sometimes for some people, if drinking more water or excessive than recommended can cause dependence.
- Other medical literature recommends consumption of one liter of water per day, in addition to exercise or in hot weather.
No Water No Lives
- Humans are estimated to survive without consuming water or holding thirst for about three to five days.
- While without eating, while still consuming water, humans are still able to survive up to eight weeks.
- However, by drinking water from a good source of water and good physical condition, a person will be able to survive more than eight weeks.
- From the existing freshwater volume, it is not all freshwater well consumed by humans and living things. This is due to the occurrence of pollution.
- Formerly, prior to the occurrence of pollution, groundwater as it is in rivers, lakes, is worth consuming.
- Natural groundwater is still able to neutralize from a variety of cargo that is harmful when consumed, such as toxins and impurities, so it is still worth consuming.
- Right now, the water that is still feasible to consume live groundwater. And that is not all groundwater, because it has happened pollution and began to contaminate groundwater with sea water seeping deep into the soil.
- The hydrogeologists argue that the most feasible and the best source of springs to be consumed is the source of water coming from volcanic mountain springs.
