“Don’t ever take a fence down until you know why it was put up.” Robert Frost.
This planet is mainly a mass of water and only a small portion of it is land. Despite all that only a minute share of water in the planet (2.5%) is potable. Most of the latter is locked up as ice while only one per cent is available in lakes, rivers and underground water tables for human consumption. Human body is 65-70% water. Therefore, human health and life on this planet depend on water to a very great extent. If one understands this one could easily comprehend how important it is to keep the water balance adequate to remain healthy all through one’s life.
Water makes up more than two thirds of the weight of the human body. Human brain is made up of 95% water; blood is 62% and lungs 90%. Even as little as 2% drop in body water could trigger dehydration. This is not easily made out as thirst is a rather late symptom of dehydration. Early signs include day time fatigue, fuzzy short-term memory, trouble with mathematics, difficulty in focusing on small print and the computer screen, and muscle pains.
Water is very essential for many of the body functions just as oil and petrol are needed for a car to run. Every cell function needs water. Water serves as a lubricant, it forms the base for saliva, makes up the fluids that bathe the joint capsule, controls the body temperature, regulates metabolism and helps maintain the normal healthy bowel motion. In addition, adequate water intake is essential to keep diseases at bay. Even common cold, sore throat, and ‘flu like illnesses could be prevented to a great extent with adequate hydration to keep the mucus membranes healthy to resist the onslaught of viruses. The minor illness syndromes, mentioned above, are the ones that cause the largest sick-absenteeism in the world every day causing billions of dollars loss to the industry.

Tens of millions of people in Bangladesh have been exposed to toxic levels of arsenic from drinking contaminated groundwater, putting them at risk of an early death, US researchers say.
 Arsenic causes cancer and is toxic to the liver, skin, kidney and the cardiovascular system. They said more than 20% of deaths in a 10-year study of 12000 Bangladeshis were caused by arsenic exposure from contaminated drinking water.
“Tens of millions of people there are at high risk of dying early. Something needs to be done urgently to reduce the exposure to arsenic for this population and find alternative, safe drinking water sources,” said Dr. Habibul Ahsan of the University of Chicago Medical Center, whose study appears in the Lancet.
Arsenic causes cancer and is toxic to the liver, skin, kidney and the cardiovascular system.
Ahsan said the West Bengal region of India, Argentina, Chile and parts of Mexico and the US states of Nevada, New Mexico and New Hampshire have areas where people drink groundwater from arsenic-contaminated wells.
Ahsan’s team estimates as many as 77 million people, or half the population of Bangladesh, have been exposed to toxic levels of the poisonous element since the installation of hand-pumped wells to tap groundwater in the South Asian country in the 1970s.
The World Health Organization said in a statement the exposure was “the largest mass poisoning of a population in history.” Continue reading Contaminated groundwater threatens millions

Mining companies operating in South Africa are lagging behind countries like Australia in terms of waste management, science-based services group DuPont said on Wednesday.
 Mine drainage activities “Mining houses in Australia are taking a more proactive approach and are currently adopting best practices aimed at preventing environmental damage, rather than repairing damage already done,” Carlman Moyo, managing director for DuPont Sub-Saharan Africa said in a statement.
South African mining houses were spending millions of rands combating the growing problem of poor quality water flowing into the environment and causing pollution.
However, the reactive nature of the methods being used was having limited effect on repairing the damage caused.
“It is vital that new waste management strategies are integrated into the core activities of all South African mining organisations in order to prevent future damage,” Moyo said.
Until waste control was integrated deep into the culture of mining organisations, it would not be effective.
“Pollution can be caused by something as uncontrollable as heavy rainfall, flooding or earth tremors.
“In these cases, emergency plans are not enough. and preventative measures need to be in place before things go wrong.” Continue reading SA mining spends millions to combat water pollution

A fight breaks out as student Vikas Dagar jostles with dozens of men, women and children to fill buckets from a truck that brings water twice a week to the village of Jharoda Kalan on the outskirts of New Delhi.
 Wei River Several thousand kilometres away, in central China, power-plant worker Zhou Jie stands on the mostly dry bed of the Wei River, remembering when he used to fish there before pollution made the catch inedible. Dagar and Zhou show the daily struggle with tainted or inadequate water in India and China, a growing shortage that the World Bank says will hamper growth in the world’s fastest-growing economies.
It also pits water-intensive businesses such as Intel’s China unit and the bottling plants of Coca-Cola against growing urban use and the 1.6 billion Chinese and Indians who rely on farming for a living.
“Water will become the next big power, not only in China but the whole world,” said Li Haifeng, the vice-president at sewage-treatment company Beijing Enterprises Water. “Wars may start over the scarcity of water.”
Water demand in the next two decades will double in India to 1.5 trillion cubic metres and rise 32 percent in China to 818 billion cubic metres, according to the 2030 Water Resources Group, a research collaboration between the World Bank, management consulting firm McKinsey & Company and industrial water users such as Coca-Cola.
