MONITORING OF WATER QUALITY PARAMETERS IN THE VIDUR RESERVOIR (VILLUPURAM DISTRICT, TAMIL NADU,

Some physical and chemical water quality characteristics of Vidur reservoir were investigated in this study. Vidur is a village panchayat in Tamil Nadu's Villupuram district. Vidur is located between Chennai and Villupuram in Tamil Nadu's northeast. Water quality metrics are an important factor for determining whether or not water is suitable for various uses. A one-year investigation of several water quality indicators in Vidur reservoir was conducted (October 2015 to September 2016). The samples were taken in the morning and evaluated for physical and chemical parameters on a monthly basis. Temperatures of air (atmospheric), water, pH, free carbon dioxide, dissolved oxygen, turbidity, electrical conductivity, total dissolved solids, total alkalinity, biological oxygen demand, chemical oxygen demand, chloride, and nutrients were all taken into account. Summer had greater values than the other seasons, according to the findings. The reservoir is hypereutrophic and contaminated, according to phosphorus concentrations.
