摘要：The present study aims at the assessment of groundwater quality in and around Tumkurdistrict and in an erstwhile freshwater stream carrying huge quantities of domestic,agricultural and industrial effluents. Groundwater samples have been collected frombore wells and open wells and subjected to a comprehensive physicochemical andbacteriological analysis. The study reveals that 52.13% of the samples were non-potabledue to the presence in excess of several water quality parameters as per the standardslaid out by the Bureau of Indian standards (BIS). Nitrate, total hardness and iron werefound to be the chief culprits. Nitrates account for 50%, and total hardness and iron for33.3% of the non-potability of samples. 50% of the samples examined indicated bacterialcontamination of the groundwater.
