Awareness, Understanding & Action
How do we determine the quality of Water? How do I read a Water testing report and understand what it means? This and many more questions are in the minds of so many people.
This article will help you understand Water Testing standards and assist you in making better decisions to protect you and your family.
If there are multiple sources of Water at the sampling point, then Acceptable Limit is what should be considered.
Example: If there is a borewell water source and a Cauvery Water connection at home, then a sample of either Borewell or Cauvery should conform to the Acceptable Limits.
In the absence of Alternate sources of water, Permissible Limit can be considered.
Example: If you only have borewell water at home and no Cauvery connection, then the Borewell water should conform to the Permissible Limits.
Most laboratories will need a sample of at least 2 litres collected in a clean bottle.
It is recommended that you at a minimum check for parameters related to Physical, Chemical & Biological Contamination.
What are Physical parameters?
Colour & Odour
What are Chemical parameters?
Some of them are TDS (Total Dissolved Solids), Nitrate, Sulphate etc.
What are Biological parameters?
Faecal Coliform & E-Coli
What type of Water Filter should I use?
- It is important to note that not all devices can work on all contaminants
- UV filters can take care of Biological contamination.
- RO based filters can remove chemical contamination but it is recommended to test your water before you buy a RO filter. Because if your water source has low TDS then the RO purifier will further reduce it to a very low TDS level.
Awareness & Action is needed now to ensure that safe drinking water is available to everyone.
