During the process of awareness creation amongst school children, I learnt from a student that there exists a YELLOW COLORED hand-pump in their locality (in Bangalore) which is not used as a regular source of water. During the two days of water problem in Bangalore residents of that locality used that water for drinking and cooking purposes and as a result faced digestive problems.
This raised a curiosity in me to trace out the reason behind YELLOW COLOR coding of that particular hand pump.
I tried searching for the same in websites and found that RED COLORED hand pumps indicate ARSENIC contamination in the aquifer.
In this regard, I would like your guidance regarding the COLOR CODING GUIDELINES available in India and the source from which I can get the detailed information.
Also please let me know the government authority handling the same.
