The drinking water quality in certain parts of the city has reached dangerously low levels.

How’s it measured? When talking about the water quality here, it’s the Total Dissolved Solids (TDS). It’s the amount of organic and inorganic material like metals, salts, and minerals, dissolved in a given volume of water. Drinking water below or above the TDS permissible levels can be hazardous and cause health issues.

  • In some parts of the city, the TDS levels were above the maximum rate of 250-300 parts per million (PPM) litre. For example, in Electronic City, the TDS level was as high as 1,236. The samples were taken between January and May this year.
  • The areas chosen also looked at the hardness levels. Hardness is determined by the milligrams of calcium carbonate per litre. In Electronic City, the hardness level ranged from 8-580PPM. The numbers show hardness levels range from soft to hard.

Who did it? The study was done by DrinkPrime, a subscription-based service for water purifiers. They collected samples in designated bottles and sent them to a private lab in the city.
