摘要：The hydro chemical quality of groundwater in Walajah block in Palar river basin at Vellore District has been studied. Totally 48 water samples were collected, out of four sampling location during the month of January, April, July and October for three years of 2009, 2010 and 2011. The samples were analysed for various parameters such as turbidity, pH, electrical conductivity, alkalinity, hardness, iron, manganese, nitrate, chloride, fluoride, sulphate and chromium. Based on the analysis, water quality Index (WQI) was calculated. According to the WQI, the water quality rating is done and it reveals that 60.42% are excellent, 25% are good, 6.25% are moderately polluted, 2.08% are severely polluted and 6.25% are unfit for drinking use. This study reveals that the groundwater in Walajah block, situated at Palar basin in Vellore district is deteriorated by the parameters such as total dissolved solids, total alkalinity, total hardness, nitrate and chromium.
