I have already posted a query and was advised by many experts to retest the water. Hence I have tested again the water sample at King Institute. Guindy, Chennai. Unfortunately the result shows the water is not suitable for drinking. Hence I would like to seek your expert advice on how to make the water potable and avoid the white cement formation.
I have attached an Excel sheet with the detailed results and summary.
Many thanks to all in advance.
