The aim of the study was to evaluate the water
quality impact caused due to the operations of common hazardous
waste landfill facility (CHWLF) in Gummidipoondi industrial
estate, Tiruvallur district, Tamilnadu, India. The watershed area
of the hazardous waste landfill facility was delineated using
Arc-GIS tools and prediction of ground water flow direction was
carried out using three-dimensional ground water flow model
using VISUAL MODFLOW software. The water quality analysis
was performed in the upstream and downstream directions of the
project site and the results showed that all the tested parameters
were within the BIS 10500:2012 drinking water limits, except pH
which showed slightly acidic characteristics in certain locations.
The tested water samples mostly belonged to the Ca + Mg-HCO3’
type as classified using the multivariate analysis method using
piper diagram. Co-relation between the water quality parameters
were determined using statistical analysis of Pearson's correlation
coefficient (r) values.
