Abstract - Rapid population growth, urbanization, and
the vehicles used. Door-to-door collection was implemented in 57 wards using rickshaw trolleys and hand carts. In 53 wards, residents disposed of waste directly into nearby dhalaos (waste storage points) or road bins. Total Waste Generated: Approximately 1600-1700 metric tons per day (MTD). MSW is transported by vehicles owned by Lucknow Nagar Nigam (LNN), with no use of private vehicles. LNN operates a fleet consisting of 22-23 dumpers, 6-10 tractors, 48-54 trucks, and around 100 Chhota haathi vehicles to transfer waste from primary and secondary collection points to landfill sites (Rawat et al., 2022).
industrial expansion, many countries are experiencing increased environmental pollution, which negatively impacts both quality of life and ecological systems. These pollutants often enter the soil through various channels, such as improper waste disposal, industrial and urban wastewater discharge, sewage sludge, pesticides, fertilizers, and unauthorized dumping of household waste. The use of untreated solid waste and sewage effluent in agriculture is a significant source of toxic metal and organic pollutant contamination in soils. This issue is particularly pressing in developing countries, where the disposal of untreated municipal solid waste (MSW) poses a major threat. The presence of hazardous pollutants in this waste can have serious consequences for both human health and the environment. This study focuses on assessing the impact of leaching pollutants from municipal solid waste on the quality of sub-soil.
Groundwater, a primary source of drinking water, accounts for over 90% of the world's fresh water and is a critical reservoir of clean water. Compared to surface water, groundwater is generally less polluted and its suitability for various uses depends on its quality (Singh, et al., (2011). Monitoring water quality is essential for maintaining human health and the stability of aquatic ecosystems. In India, MSW is frequently disposed of in low-lying areas without proper precautions, resulting in open dumps that are called landfill sites. This unregulated disposal negatively impacts the environment and human health, particularly through groundwater contamination. The waste decomposes and produces leachate a toxic liquid with various harmful chemicals that can seep into groundwater if no protective measures are in place (Archana et al., 2014; Singh and Uchimura, 2023; Kumar and Kumar Rana, 2024). MSW is complex refuse consisting of various materials with different properties. Some of the components are stable while others degrade because of biological and chemical processes (Gupta et al., 2013; Amano et al., 2021).
Key Words: MSW, Leaching Pollutants, Water Quality and Toxic Metals, soil.
1.INTRODUCTION Development often significantly impacts the environment, affecting ecology, water resources, and plant life. Rapid urbanization and population growth have further stressed groundwater resources and increased municipal solid waste (MSW) production. Leachate, a liquid produced from decomposing MSW, poses a major threat to water resources, human health, and sanitation. This highly concentrated mixture of organic matter, inorganic compounds, and heavy metals forms during the acidic phase of waste decomposition, with its composition varying based on waste type, depth, moisture, and age (Kjeldsen et al., 2002). MSW is also known as garbage. MSW is the combination of commercial waste, construction waste, demolition waste, agricultural waste. It includes trash, grass cutting, food scraps, disposable, appliances, kitchen waste, common household waste, synthetic waste, leather, waste from destruction of building, road, bridges, or other structure (Archana et al., 2014). In 2022, the MSW collection system in Lucknow city followed a structured process with the use of various vehicles to collect and transport waste across the city’s 110 wards. Here is an outline of the data related to waste collection and
