What is the maximum permissible limit of Nitrate (as NO3), as per IS;10500? In some copies of the standard provided to us during training programmes it is 45 PPM and in some it is 100PPM. The source of contradicting information is the copy of IS:10500, provided to us during different training programmes, kindly clarify?
