The importance of a clean water supply is evident everywhere. People, plants and animals all need it to survive. Water is essential to all living creatures. When the water supply is not clean, it is not healthy. When contaminated it cannot sustain life. Once it is contaminated, it must be cleaned to be healthy once again.
People and animals need clean water. A human body is over 70% water. Every mammal body function and part needs water to survive and work effectively. Contaminated water can harm every system in the body. Not enough clean water can also do irreversible damage to the brain or other vital organs.
Humans use it in many ways. Cooking, bathing, washing and drinking. Taking a bath or shower in dirt, would just not get a person clean. We do not cook with dirt, nor do we drink water that we can see is dirty.
Animals have the same need for clean streams, lakes, and rivers. Mammals, birds, fish and reptiles depend on a clean supply for their survival. Many animals have perished due to lack of clean, healthy supply.
Contamination happens in a variety of ways. Man made disasters like a large oil spill. Pollution from man made manufacturing releases pollution into the air, which will contaminate the supply. Throwing trash randomly into a stream or lake is another way to contaminate the supply.
Mother Nature also contributes to an unhealthy supply. Drought, earthquakes, tsunami, tidal waves, and any number of other natural disasters can contaminate the supply. Nature also has its own way of cleaning up the mess she delivers, but it can take hundreds of years to once again become a healthy resource
Humans are careless and do not think that there will ever be a time when all water is unsafe to use. We get used to having clean water readily available. When there comes a time that clean, healthy water is unavailable, what will happen to the human race?
The effect of unhealthy water is evident in countries that have suffered from earthquakes and other natural and manmade disasters. Cholera, dysentery, and dehydration is prevalent in any place on earth that has had a major disaster.
Water is used by every bodily function. Without clean healthy water, the body cannot function. Clean drinking water should be abundant. Studies have shown biological or chemicals in some form contaminate most of the drinking water supply. As a result, we are studying ways to clean drinking water for consumption.
Some water is cleaned by a filtration system. On a large scale, city water is cleaned at a central location and travels through a pipe system to households, seemingly clean and healthy. Some rural homes have a private well system that pumps water from the land the home is on into the home. Farm and lawn care chemicals can contaminate a private water supply and not be detected by the homeowner until residents become ill.
We have a personal stake in insuring clean healthy water. Many home and business owners filter their own water to be sure it is clean and healthy. Filtering water before consuming is one way to be sure to have a clean water supply.
Locating places to 샌즈카지노 find clean drinking water requires nothing more than some knowledge of hydrogeology and some simple observation and inquiry. Groundwater sources often provide safe water. Finding them is something anyone can learn to do.
Many places in the world suffer from a shortage of clean drinking water. A number of governmental, non-governmental, and private organizations are dedicated to finding and developing sources of clean water.
In the quest to find and provide clean drinking water for the people of the world, these organizations often look to underground sources of water (groundwater) as the solution.
So, if you were in need of a water well and a reliable source of water, where would you most likely find groundwater? What would be the most likely places to find clean drinking water?
Locating groundwater does not require extreme expertise or education. Finding sources of water underground is both a science and an art.
One thing you do need is a basic knowledge of hydrogeology, which is not really difficult to obtain. In addition, finding groundwater requires some basic skills in observation and inquiry.
Groundwater is subject to the forces of gravity. It tends to flow downhill just like water on the surface does. Groundwater usually originates as surface water. Rain collects in depressions, lakes, rivers, and streams and then percolates into the ground at a location called a "recharge area". It is called this because it is the point where the groundwater source is replenished or "recharged".
One basic principle of groundwater dynamics is that it always flows from a recharge area to a discharge point. The discharge point is where the groundwater finds its way back to the surface.
The discharge point is usually at a lower elevation than the recharge area. Since groundwater is influenced by gravity, it is safe to say that it flows downhill, or from a higher elevation to a lower elevation.
Discharge points can occur in many places, like springs, rivers, or streams or along a lake shore or even beneath the ocean.
Therefore one place to find clean water is beneath the surface of the ground along the banks of streams, rivers, and lakes. In fact, this is often where wells are drilled or subsurface water collection systems are placed.
Another basic principle of groundwater movement is that water underground basically follows the contours found on the surface of the ground.
If you are looking for clean water, try to visualize the groundwater beneath your feet. The hills and depressions you see around you are clues as to where the water may be found underground.
Intuitively, we understand that, since water flows downhill, we are more likely to find water in a low depression than on the top of a hill. So we will have better luck finding water if we drill a well at a lower point of the landscape than at a higher point.
So the best places to find clean drinking water are at lower elevations like valleys and basins and ravines.
Asking questions and making observations will go a long way toward finding water in areas that may, at first, appear dry and barren.
Try to find out where people in the area presently get their water? Ask the residents and have them show you the location of their water source.
If you look at surrounding wells, you can see the depth to the groundwater in the area. You may also be able to observe into what kind of sediment those wells are drilled or dug.
If there are drilled wells close by, the village or responsible government agency may have information on the well. They may know its depth and the sediment or rock types they found when the well was drilled.
If you are looking in the bottom of a valley or depression, keep in mind that groundwater is most likely found in a gravel or sand layer. These water-bearing layers are referred to as "aquifers", and may be covered by vegetation and layers of silt or clay.
Groundwater may also be found near springs in the area. You can determine a lot about the aquifer by finding out if the spring flows all year or if it is seasonal. A spring that flows all year most likely comes from a good, productive aquifer. If the spring dries up periodically, then you can assume that the aquifer from which it comes dries up also.
The flow characteristics of a stream can also be a clue to the location of groundwater. If the flow of a stream is greater in one area, this may be an indication that groundwater is discharging into the stream. This may be a good area to drill for water. Sometimes, the ground directly beneath a dry stream bed can hold groundwater.
Observe the plants and animals in the area. If there is a place where vegetation remains green during the dry season, it may be drawing shallow water from the ground. Animals are good at finding water, so observe where they drink or where they dig for water.
Evaporation of groundwater can often leave behind a crust of white salts on the surface of the ground. If you observe an area of salt on the surface, it may be an indication that there remains water underground.
Outcroppings of rock, tilted layers of rock, and layers of sandstone or limestone may also be clues to places to find clean drinking water. Groundwater will flow down a tilted rock layer along the direction of the tilt. Limestone and sandstone may have cracks that will yield water.
Keep your eyes open and cover a broad area in your observations. Even though it is best to have a well close to where people live, it is more important to have a productive source of water, as long as it is not too far away.
There are other ways to find clean drinking water. Methods such as electrical resistivity and seismic refraction are high tech and expensive ways to locate groundwater.
But, with a little knowledge, observation, inquiry, and common sense, you can locate places to find clean drinking water.
