Take a safe sip
As the mercury soars, so does the prevalence of waterborne infections like typhoid, cholera, hepatitis and diarrhoea. The World Health Organisation attributes 88 per cent of the four billion cases of diarrhea that occur annuallyto unsafe water, inadequate sanitation and hygiene.
The water we use at homes comes primarily from underground bore well tanks or municipality supply. Most of the tap, underground and well water is not safe for drinking due to heavy industrial and environmental pollution, and has impurities of microbial (bacteria, viruses etc.) and chemical (lead, nitrate, arsenic, chromium and fluoride) nature. Toxic bacteria, chemicals and heavy metals pollute our natural water sources.
Whether we receive water from a bore well or a community water system, it must be treated at the point of use. A good water filtration system installed in our home is the only way to ensure the safety of drinking water. Water from community water system is commonly treated/purified at home level by boiling, filtration, purification or reverse osmosis. The aim for safe drinking water should be to minimise the count of microbes, chemical toxins and pesticides, and retain useful minerals like calcium and magnesium.
