HOW SAFE IS YOUR TAP WATER?
You Know that our tap water is not as good as it was during our forefather's time! Due to climatic changes, draught, alarming levels of salinity, industrial wastes, sources like river, catchements and reservoir systems are under dire stress which deteriorates the water quality day by day. Further, one does not get sufficient water from a river and has to resort to underground water, which generally is contaminated with dissolved impurities.
By the time water (municipal or ground water ) reaches your tap, it may get contaminated on way which leads to common water problems. Although water treatment plants meet 'The Safe Drinking Water Standards', but still water pollutants are present in your tap water.
Increasing Dissolved Impurities
Water might be pure while leaving the treatment plants but when it travels miles through the ageing pipes, which are corroded at many places, the rust from pipes become soluble and gets released into water and is generally invisible. Shocking but true! Further at many places, when municipal drinking water does not come for more than 2 to 5 hrs. this not only leaves water pipelines empty but also makes them prone to oxidation and rusting.
Pesticides are deadly chemicals used to eliminate weeds, insects and other harmful elements in crops. But their consistent use has however produced its own harm. Surprisingly, pesticides too are entering our ground water and are contaminating our drinking water.
Arsenic is a semi metal element in the periodic table. It is odourless and tasteless. It can enter drinking water supplies from natural deposits of the earth or from agriculture or industrial practices. This problem is widely experienced in many regions across the country. Consumption of Arsenic can cause skin damage, circulatory system problems and an increased risk of lung & kidney cancers.
Fluoride is a major naturally occuring contaminant in drinking water. It is found in very high levels in most areas. Low levels might prove beneficial in preventing dental problems but its high levels can cause structural tooth damage and very high level can cause skeletal damage.
Many old homes & building have pipes & plumbing fixtures that contain lead. Lead can easily leach from pipes into drinking water. Its long term effects include stroke, kidney problem and cancer.
Metals like Mercury, Zinc, Copper and Cadmium usually enter the water supply as Industrials wastes and their excessive concentrations can cause physiological damage to humans, including damage to the central nervous system
Excessive Bacteria & Viruses
At most of the places, Municipal drinking water comes for not more than 2 to 5 hrs. Therefore the water is stored in overhead tanks that results in excessive bacteria and viruses growth and this can lead to diseases like Cholera, Dysentery, Diarrhea and Typhoid.
