The prime aim of this study was to assess the physicochemical properties of water reservoirs from magnesite mine surrounding four sites (each direction) on three seasons such as summer, winter, and rainy season. The results attained from the physicochemical analysis states that all the surrounding water reservoir samples have been severely polluted by both essential and non-essential elements. Predominantly the water sample taken from the site I of three seasons has been severely affected by the metal pollutants. The site I water sample unacceptable (mg L-1) physicochemical properties such as turbidity (16.20±1.3; 15.23±1.8; 18.29±1.5), conductivity (2742.30±2.7; 2652.24±2.1; 2785.25±2.1), TDS (2085.13±4.3; 2024.15±2.1; 2113.10±1.2), TSS (712.21±2.1; 692.31±1.12; 711.12±1.5), hardness (765.38±2.4; 738.65±2.1; 781.23±2.9), BOD (208.12±1.7; 201.31±1.2; 212.31±1.5), COD (312.74±0.98; 301.54±1.21; 307.721±1.51), DO (1.12±.39; 1.01±.28; 1.02±0.23), Ca (265.28±1.21; 252.14±1.34; 275.34±1.17), Mg (124.56±1.54; 117.32±1.28; 135.28±1.62), Cl (1248.64±2.69; 1203.17±2.18; 1351.21±1.34), Zn (75.61±1.85; 71.52±1.02; 78.32±1.21), Cd (24.54±0.84; 21.28±0.61; 26.25±0.71), Pb (11.52±0.95; 8.2±0.52; 12.35±0.52), and Cr (3.1±0.054; 2.9±0.063; 3.5±0.21) contents of summer, winter, and the rainy season correspondingly. Among these three seasons, the water sample collected during rainy season possesses more quantity metals than other seasons. These results confirmed that the metal contamination has been spreading from the abandoned magnesite mine tailing. These unacceptable physicochemical properties could cause severe ecological damage to the water ecosystem.
