Total Dissolved Solid (TDS) and Our Drinking Water

As per World Health Organisation, the Total dissolved solids (TDS) is the term used to describe the inorganic salts and small amounts of organic matter present in solution in water. The principal constituents are usually calcium, magnesium, sodium, and potassium cations and carbonate, hydrogencarbonate, chloride, sulfate, and nitrate anions. (WHO).

EFFECTS ON HUMANS;

In early studies, inverse relationships were reported between TDS concentrations in drinking water and the incidence of cancer, coronary heart disease, arteriosclerotic heart disease , and cardiovascular disease.

Total mortality rates were reported to be inversely correlated with TDS levels in drinking-water. It was reported in a summary of a study in Australia that mortality from all categories of ischaemic heart disease and acute myocardial infarction was increased in a community with high levels of soluble solids, calcium, magnesium, sulfate, chloride, fluoride, alkalinity, total hardness, and pH when compared with one in which levels were lower.

Therefore, a balanced level of the TDS should be present in drinking water to lead the healthy life. WHO recommends that for fair taste it is good to have 300 ppm to 600 ppm TDS in water. Normally tap water possess TDS between 200 ppm to 400 ppm is also good for heath.

Lower the TDS have the good taste of water. Because of this reason probably most of the bottled water have the less amount of TDS which varies usually from 90 ppm to 130 ppm.

But be reminded that so called bottled mineral water do not have sufficient minerals but in fact they contain less amount of TDS.

Therefore, it is advisable to put tap water in MATKA / GHADA / SURAHI and they it should be used for drinking.

Water is life so be careful what you drink.

Watch out the video on below link to see the experiment of different types of water.
