“…The pH of fly ash is alkaline in reaction and dissolution of the same can increase the pH of the surrounding ground water. The results were in line with the findings of Khan and Umar (2019) and Krechetov et al (2019). The temperatures near RTPP ranges from 22 °C and 43°C which raises the alkalinity of water because at that temperature the solubility of CO 2 reduces.…”

Ground water samples were collected from four radiant directions (north, south, east and west) and from each direction five samples were collected from four distances at 1.0, 2.0, 4.0 and 8.0 km from Rayalaseema Thermal Power Plant (RTPP). The ground water had alkaline pH and electrical conductivity was within the permissible limit. The abundance of cations in four radiant directions and at four distances are in the order of Na + > Ca +2 > Mg +2 > K + . The order of anions observed as Cl -> HCO 3 -> CO 3 -> SO 4 -2 . The Sodium Adsorption Ratio (SAR) of ground water was within the permissible limit in all directions and distances. The Residual Sodium Carbonate (RSC) is < 1.25 m eq -1 in the ground water collected at four directions and distances thus becoming suitable for irrigation. The water samples at north, south, east and west direction arecategorized as very high saline low sodium water (C 3 S 1 ) but in east direction at 8.0 km radius and at 1.0 km radius of west direction was classified as very high saline medium sodium water (C 3 S 1 )
