"Don't just boil your drinking water, but get it tested," the Department of Mines and Geology has warned people living in certain areas of Mysore. The Department which began its chemical analysis of groundwater in Mysore during 1992-1993 and has been constantly monitoring its quality since then, has found a high concentration of nitrates and organic chemicals in the groundwater particularly in Mysore South, Rajendranagar, Kesae, Kyathamaranahallo, Paduvaralli and Hinkal.
