FACTS ABOUT WATER
Why is water so very essential?
Every part of the human body depends on adequate hydration. Skin becomes dry and cracked in the absence of enough water. Blood thickens when the body lacks water, thus making it difficult for the heart to pump and distribute blood to the rest of the body. Without water, kidneys would be unable to remove toxins, wastes and salts from the blood. Organs of the digestive system work harder than normal and become strained in case of inadequate hydration, which results in constipation and abdominal cramps. Similarly, the brain also needs adequate supply of water.
Since all the functions of the body require water to function properly, it is more so important to drink pure water otherwise the functioning of these vital parts would get affected. In fact, approximately 70% of the human body is water (Blood - 92%, Brain - 75% , Lungs - 86%, Kidney - 83%, Bones - 40%, Muscles - 75%, Heart - 75%, Liver - 86%). The only thing more important than pure water to the human body is oxygen. Average human body requires eight to ten glasses of water a day. Pure water is a human necessity.
What causes water borne diseases?
Apart from chemical pollutants the major culprits are Bacteria and Viruses which cause most of the commonly found water borne diseases.
Bacterial diseases : Gastro-enteritis, Typhoid, Cholera, Paratyphoid, Dysentery and Diarrhea.
Viral diseases : Polio, Dysentery, Gastro-enteritis, Diarrhea and Jaundice (Hepatitis)
How is drinking water treated?
Most surface waters are first treated with chemicals that combine with dirt particles. The dirt is then filtered out of the water, making it clear. Then the water is disinfected. Occasionally, additional treatment is needed to solve special problems. Treatment, as described above, does not remove dissolved toxic chemicals.
A chemical disinfectant is added to the drinking water at the treatment plant. Chlorine is the most common disinfectant.
Which is better, purified water or bottled water?
Bottled water is "purified & packaged drinking water". The machines used by the manufacturers are mostly the same as that of point-of-use treatment devices, though of a much larger scale. The TDS of the bottled water varies with the brand and is generally kept at the most acceptable and likeable level. Basic aim is to provide you with 100% safe water with no hassles and involvement. Bottled water is not purified at point-of-use (i.e. your home or office). Therefore, there can be a chance of recontamination if stringent quality control measures are not followed. With proliferation of brands and local manufacturers, chances of spurious and inferior water being made available to you are high. Moreover, there is always the hassle of collecting and replacing the bottle on a daily basis. Also, in the long run this could prove to be quite expensive. Compared to this is your reliable water purifier, which purifies the water right at the point-of-use in your home or office, leaving behind any scope of spurious / re-contaminated water and giving you absolutely pure, safe and hassle free water.
Water related diseases are a major cause of morbidity and mortality worldwide. In 2001, infectious diseases accounted for an estimated 26% of deaths worldwide. Most of these are caused by 'classical' water related pathogens, such as typhoid and cholera but newly recognized pathogens and new strains of established pathogens are being discovered that present important additional challenges to both Water Treatment and public health sector. Between 1972 & 1999, 35 new agents of disease were discovered and many more have re-emerged after long periods of inactivity.
In 2001, a WHO review identified 1415 species of infectious organisms pathogenic to humans. This implies that existing water treatment technologies need to be continuously verified, upgraded and incorporated with fail-safe mechanisms.
What problems can one associate with the presence of Iron and Heavy Metals in water?
Excess iron is also an inherent water quality problem in ground water and is prevalent mostly in hilly regions and in the North Eastern part of our country. Excess iron in drinking water beyond the permissible limit of 0.3 ppm causes digestive disorders. A total of 138,670 habitations spread across 16 states in the country are found to be affected with iron contamination.
CGWA report warns, "Ground water in most of Delhi contains harmful heavy metals such as lead, chromium and cadmium". Heavy metals do not dissolve in blood; instead they get deposited in the bones, teeth and soft tissues including those of brain. Over 100 micrograms of lead in the blood can irreversibly damage a child's growth. It can also decrease his/her IQ. In adults, it causes miscarriages and irritability. Children are more susceptible to lead poisoning.
AIIMS results show unacceptably high lead levels in the blood samples, over 20 units in 41% of the children surveyed and over 10 units in the rest.
