What is Water
Water is not found in its purest form in nature. It is always contaminated with physical, chemical & biological impurities. Proper filtration is of much importance to prevent low pressure diffuser like emitters from clogging. It is important to understand that all water is not created equally. On a strictly scientific level, water can be described as H2O. This symbolizes the two elements that water is comprised of, two hydrogen atoms and one oxygen atom. But going beyond the scientific definition there are many different types of water that are consumed.
But going beyond the scientific definition there are many different types of water that are consumed. While all the water will share the common makeup of elements, some will contain other "ingredients" that can either make the water you consume better or in some cases worse for you. While tap water can contain all kinds of nasty little additives, such as lead and chlorine, alkaline water. Such as in the form of ionized water, is on the opposite side of the spectrum and will actually help you to improve your health. Just because you are drinking water doesn't mean you are drinking healthy water. Healthy drinking water is PH balanced water.
Source of Water Water is generally classified into Two group's Surface water & ground water.
Surface WaterIt is just what the name implies; it is water found in a river, lake or other surface impoundment. This water is usually not very high in mineral content, and many times is called "soft water" even though it usually is not. Surface water is exposed to many different contaminants, such as animal wastes, pesticides, insecticides industrial wastes, algae and many other organic materials. Even surface water found in a pristine mountain stream possibly contains Giardia or Coli form Bacteria, from the faces of wild animals and should be boiled or disinfected by some means prior to drinking.
Ground WaterIt is that which is trapped beneath the ground. Rain that soaks into the ground, rivers that disappear beneath the earth, melting snow are but a few of the sources that recharge the supply of underground water. Because of the many sources of recharge, ground water may contain any or all of the contaminants found in surface water as well as the dissolved minerals it picks up during its long stay underground. Water that contains dissolved minerals, such as calcium & magnesium above certain levels are considered "hard water." Because water is considered a "solvent" i.e. over time it can break down the ionic bonds that hold must substance together, it tends to dissolve and "gather up" small amount of whatever it comes in contact with. For instance, in areas of the world where rock such as limestone, gypsum, fluorspar, pyrite & magnetite are common, well water is usually very high in calcium content, and therefore considered "hard".
Due to the different characteristics of these two types of water, it is important that you know the sources of water-Surface or Ground. Of the 326 million cubic miles on earth, only about 3% of it is fresh water, and 3/4 of that is frozen. Only 1/2 of 1% of all water is underground; about 1/50th of 1% of all water is found in lakes and streams. The average human is about 70% water. You can only survive 5 or fewer days without water.
Water Is Absolutely Vital To Our BodiesJust like the surface of the earth, our bodies are mostly made up of water. The average adult contains 40 to 50 quarts of water! The water in your body must be renewed every 10-15 days. With the intake of foods such as fruits and vegetables, you are receiving water, but you still must drink at least 8 glasses of water daily to enable your body to function properly. Water is the base for all bodily function. Water is essential to sustain life, and a satisfactory supply must be made available to consumers. Every effort should be made to achieve a drinking water quality as high as practicable. Protection of water supplies from contamination is the first line of defense; Source protection is almost invariably the best method of ensuring safe drinking water and is to be preferred to treating a contaminated water supply to render it suitable for consumption.
Once a potentially hazardous situation has been recognized, however the risk to health the arability of alternative sources, and the arability of suitable remedial measures must be considered so that a decision can be made about the acceptability of the supply. As far as possible, water sources must be protected from contamination by human & animal waste, which can contain a variety of bacterial, viral and protozoan pathogens and helminthes parasites .Failure to provide adequate protection and effective treatment will expose the community to the risk of outbreaks of intestinal and other infectious diseases. Those at greatest risk of waterborne diseases are infant and young children, people who are debilitated or living under unsanitary condition, the sick and the elderly. For these people, infective doses are significantly lower than for the general adult population.
Water for lifeLife is originated in water and it is water that makes life possible. Water makes up 70 percent of body weight, blood plasma contains more than 90 percent of water, cell cytoplasm contains about 70 percent of the water. Even bone is 20 percent water. Water is needed for Transporting nutrients and oxygen to all parts of the body via blood, Marinating blood volume, removing body waste materials, helping maintain body temperature. Plants which use water to convert the nutrients in the soil into food, which keeps them alive and helps them to grow.
Your Tap Water is really that Bad or Are We Just Being Paranoid? Read OnClean water is one of the most important needs of our bodies. It is a sad fact that something as essential to life as clean drinking water can no longer be granted to us. Unsafe water is not just a third world problem. In fact, safe drinking water is even harder to find especially in industrially developed countries such as U.S. According to research articles and news, most tap & well water in the U.S. now are not safe for drinking due to heavy industrial and environmental pollution. We have reached a point that, all sources of our drinking water, including municipal water systems, wells, lakes, river, and even glaciers, contain some levels of contamination.
Contaminants range from naturally-occurring minerals to manmade chemicals and by products. While many contaminants are found at levels not enough not to cause immediate discomforts or sicknesses, it is proven that even low-level exposure to many common contaminants will, over time, cause severe illness including liver damage, cancer and other serious ailments. Even the chemicals commonly used to treat municipal water supplies such as chlorine and fluoride are toxic and are known to have significant adverse effect on the human body.
Watering your growing childTeach your children to acquire a taste for water, the most vital drink of all! Water is essential to good nutrition! Since our bodies are more than 50 percent water, we need to continually replenish our fluids. Hidden sources of water include milk or fruit juice, soups and stews, fruits and vegetables. Have cool water readily available for your child throughout the day. Keeping it in a pitcher in the refrigerator makes it seem more special, as does an attractive cup or glass and maybe some ice cubes or a twist of lemon peel. Don't forget to offer water often during the day, especially in warmer temperatures. If a child is well hydrated, he or she is more likely to have a good appetite.
