method of evaluating the impact of landfill leachate on underground water quality
Introduction
Landfills have been discovered to be the greatest dangers to the quality of water in underground water resources, not just in India but also in other parts of the world(Fatta et al.,1999). Over 90 percent of the Municipal Solid Wastes created in India are carelessly dumped in bare land. The amount of waste that is put in landfills or any other open place is subject to either underflow of groundwater or infiltration facilitated by precipitation or different ways that cause infiltration of water(Chatterjee,2010). During the rainy season, dumped solid and liquid wastes receive rainwater, and the decomposed by-products flow to the water sources. The liquid which is made up of many inorganic and organic compound known as leachate. This compound gathers at the bottommost of the landfill. Then it infiltrates via soil and finally reaches the groundwater hence affecting the quality of the water taken for domestic and commercial purposes(Mor et al., 2006).
Areas close to landfills have a high likelihood of having contaminated groundwater since the possible leachate source of pollution from the neighboring dumping site. This contamination of the underground water source leads to a significant risk to the resources of the groundwaters of the local people in those areas. It also affects the natural environment of the surrounding areas. Several studies have been contacted in recent years to investigate the impact of landfills on ground and surface water, and it has been much famous due to the increased world population, which depends on both surface and ground waters for survival(Saarela,2003). There exist several methods that can be used to evaluate the contamination of surface and ground waters. It can be assessed by either carrying out experiments to determine the level of impurities in the water samples collected from the nearby water sources or through the use of mathematical modeling techniques.
In the current study, we are going to establish the impact of landfills on underground water quality around Seelampur, Bhalswa, Okhla, and Ghazipur. Various chemical impurities will be tested, including heavy metals, water hardness, PH, calcium carbonate levels, etc. The research question in this study will be; Do the landfills affect the water quality of underground sources in Seelampur, Bhalswa, Okhla, and Ghazipur?
Hypothesis: landfills lead to a negative impact on underground water quality in Seelampur, Bhalswa, Okhla, and Ghazipur.
