Impact on Ground and Surface Water by Open Dumping of Solid Waste
Impact On Ground And Surface Water By Open Dumping Of Solid Waste Deteriorating soil quality and decreasing vegetation abundance is a serious consequence of open dumping of waste that has led to growing public concern. Vegetation diversity was studied at both sampling sites. Significant modifications were observed in the dumping sites ‘ soil properties.
In comparison to control sites, soils at the disposal sites showed high pH, TDS and EC regime. Various concentrations of heavy metal, i.e. Lead (Pb), copper (Cu), nickel (Ni), chromium (Cr) and zinc (Zn) were also found to be higher at the dumping sites except for cadmium (Cd), which had a higher value at the control site. Similar trend in plant diversity was observed.
Municipal solid waste management services are the third priority in municipal commitments after water supply and sanitation in most countries. They are, however, under pressure from their own legislation to move away from the current disposal practices of open dumping to filling sanitary land. The main environmental problem associated with the disposal sites is the potential risk to the soil.
Since the beginning of civilization, solid waste has been produced. During the early period, solid waste was conveniently and unobtrusively disposed of as the population density was low with large open space. Markets of commercial establishments from households. The nature varies from region to region.
Even though most of the Physico chemical parameters were within the permissible limits of BIS standards, some of them are above the maximum allowable limits of WHO guidelines. The collected solid waste must be segregated, treated and disposed in an environmentally acceptable manner. So, safe disposal of solid waste leads to safe human health and healthy environment. Moreover, segregated solid waste can be used to recover precious metals, generate electricity and produces nutrient rich soil. For better disposal of solid waste, a Landfill was designed.
