Assesment of Groundwater Quality in and around RTPP, Muddanur, Kadapa District, Andhra Pradesh, India: Using Multi Analytical and Statistical Techniques

The research study is focused on groundwater quality evaluation and current hydrochemical conditions by collecting various samples from different locations around rayalaseem thermal power plant, (RTPP) Muddanur and assessed different parameters like pH, electrical conductivity, total dissolved solids, hardness, levels of Ca, Mg, Na, K, HCO3, Cl, SO4, NO3,F and SiO2 as per standard guidelines laid down in APHA and suitability of groundwater for drinking purposes is assessed as per BIS guidelines. The state of groundwater is mildly acidic to alkaline in nature with the pH range (5.76–8.01); Electrical Conductivity (380–7660 µS/cm), TDS (190– 8830), Total Hardness (395-3900 mg/L),Na (27.47–1285.73 mg/L), K (0.73– 491.21 mg/L), Ca (7.30–167.57 mg/L), Mg (2.14–144.41 mg/L),HCO3(30.5–719.8 mg/L),F (0.199–1.45 mg/L), Cl (8.76–834.75 mg/L), NO3 (0.276–434.72 mg/L), SO4 (0.29–32.237 mg/L) and SiO2 (17.90–84.42 mg/L). The data established by spatial maps for respective contaminants and graphical trilinear Piper plot diagrams. Keywords: Groundwater; Environment; Cement industries; Hardness; Total dissolved solids
