The Bureau of Indian Standards (BIS) has adopted the European Union norms for bottled packaged water. Issued on Monday (10th Feb) the norms stipulate that the individual pesticide residue should not be more than 0.0001 milligram per litre (mg/litre). BIS has also junked its earlier testing method and gone in for the globally used capillary column method to detect pesticide residue. The change in norms come in the wake of last week's revelation by Centre for Science and Environment (CSE) that bottled water contained residues of extremely harmful pesticides.
