Evaluation Of Potential Level In The Municipal Solid Waste Of Dumping Yard Of Mandya By Using Leachate Pollution Index

Leachate is one of the most serious environmental hazards associated with landfills, especially those which are unlined and uncontrolled. Considering this, the present study investigates the leachate pollution index (LPI) of the open dumping site of the Mandya district of Karnataka using leachate characteristics from the sample collected from the open dumping site from the Mandya open dumping site. The physicochemical and heavy metals concentrations were also analyzed such as Lead (Pb), Zinc (Zn), Copper (Cu), Iron (Fe), Chromium (Cr), Nickel (Ni) and Mercury (Hg). The LPI value was calculated for the four leachate samples collected namely, L1 (28.85), L2 (28.86), L3 (28.76) and L4 (30.84) respectively. The LPI aggregate value is 29.32 which immensely exceeds the limits of the Indian standards of 7.378 for disposal. There should be immediate action for remediation plans to reduce the environmental risk and better treatment plans and incorporate a better solid waste management (SWM) system to reduce the pollution potential.
