From Construction to Contamination: Examining Soil Quality Degradation Associated with Construction and Demolition Waste in an Indian Urban Area

In light of India's accelerated urban expansion, the present research delves into an emergent environmental predicament precipitated by the unregulated disposal of construction and demolition (C&D) waste, with a critical focus on its deleterious effects on urban soil integrity.The rampant urbanization pervasive across India has catalysed an unprecedented surge in C&D waste, much of which finds its way into unauthorized dumpsites, engendering ecological perils.This investigation is centered around a residential locale in Visakhapatnam, Andhra Pradesh, besieged by the uncontrolled proliferation of illicit dumping.Employing a methodical soil quality assessment, the study juxtaposes conditions at two strategically selected sites: S1, in proximity to a C&D dump, and S2, situated 1000 meters distant, devoid of direct waste exposure.The analysis uncovers disturbing trends, including disrupted moisture profiles, a propensity for neutral to alkaline pH spectra, and a spike in electrical conductivity, signaling heightened salinity.The nutrient composition was found lacking requisite standards, coupled with an anomalous spike in organic carbona collective aftermath of C&D waste mismanagement.These revelations unearth a spectrum of ecological consequences, manifesting as deteriorated vegetative vitality, infrastructural compromise owing to hastened corrosive processes, potential aquifer contamination, and a decline in urban biological diversity.The research emphatically calls for immediate, multifaceted reforms in waste governance, augmented community consciousness, and decisive policy shifts, all converging towards the ideals of ecological conservation and the sustainable evolution of urban landscapes.
