Abstract Open dumping is the prevailing municipal solid waste (MSW) disposal technique in India. Unsanitary landfill system results release of leachate, a substance that has potential to contaminate nearby environment, including groundwater. Hence, present study was carried out vicinity Saduperi open dumpsite, Vellore, Tamil Nadu, India, explore key factors influence groundwater contamination. 18 sample wells were identified near dumpsite and total 216 samples collected between May 2021 April 2022. These categorized into four different seasons such as summer, southwest monsoon (SWM), northeast (NEM), winter. The contamination assessed using hydrogeochemical methods Piper Gibbs diagrams. leachate pollution index (LPI) Heavy metal (HPI) used evaluate potential. calculated LPI > 35 all indicates poor environmental condition. It observed about 56% sampling site affected by heavy concentrations Cd, Cr, Ni. HPI value found be more than critical 100 10 for seasons. Partial least squares-structural equation modelling (PLS-SEM) offers novel approach assessing intricate link several influencing elements quality, contrast conventional multivariate statistical technique. PLS-SEM creates Latent variables “IOT Parameters”, “Leachate “Heavy Metal” “Groundwater Quality” which quantified yield R 2 value. well ahead along direction flow values ranging from 24.7–86.5% located behind are prone get due migration leachate. Hence this shows various affect quality.
