This paper presents Groundwater quality assessment of villages affected by industrialization in Ranebennurtaluk, Haveri district, Karnataka, India. For the present study, five villages affected by industrialization were selected to measure the quality of groundwater for determining its fitness for domestic use. Bore well samples from each village were analysed for Physico - chemical variations and quality of groundwater. Comparison of Physico - chemical analysis results with Indian Standard drinking water limits shows that all groundwater samples except few are fit for drinking and irrigation purposes. The average value of pH of five villages is 7.5-8.0 which is within desired limit. However, the pH value is increasing so it may be unfit for the future use. About 75% of EC and TDS values are more than 1000 but it is acceptable. About 50% of Water samples containing chloride in excess of 250mg/l are considered undesirable for drinking purposes which may lead to cardiovascular diseases. The concentration of sulphate for each sample of villages is within desirable limit. Also it is found that 25% of samples containing total hardness more than 300 mg/l which is undesirable. In future there may be threat of decrease in groundwater quality. |
