The Impact

Warangal city generates three hundred tons of garbage daily which is dropped into the Rampur dump yard by Warangal Municipal Corporation (WMC). Dumping of wastes will lead to the formation of leachate which in turn will cause environmental issues like soil and ground water contamination. Chemical analysis of leachate indicates that calcium, chloride, sodium and magnesium are the major ions, along with organic content. This leads to contamination of soil as well as ground water bodies. In this study, authors have attempted to know the behavior of soil under the influence of leachate. Contaminated specimens were prepared and tested for Atterberg limits, shear strength, swell potential and hydraulic conductivity of CH and SC which are present in the dumping yard. Index properties, hydraulic conductivity and swell potential decreased with increase in leachate concentration. Unconfined compressive strength also showed an increase. The decrease in hydraulic conductivity indicated the clogging of pores. In a nutshell, the present work deals with the impact of leachate on the index and engineering properties of CH and red soil.

Abstract Municipal solid waste (MSW) disposal is a rapidly expanding sector that caters to the rising demand for disposal facilities; as a result, MSW treatment is becoming a significant challenge in concern to environmental and public health. The by-products of solid waste dumped in landfills have negative consequences on the environment and people living near disposal sites. This research aimed to assess whether the disposal of garbage in landfills affected the people who live near them. Consequently, residents living near MSW disposal facilities are exposed to various risks. A systematic questionnaire was devised and disseminated in this research to examine the adjacent people's concerns and attitudes around the landfill of the rapidly expanding Siliguri city of West Bengal. It was accomplished by assessing the opinions of persons living within the 1000m of the landfill site and how it impacts their life. The novelty of the research includes geographical analysis of physical impressions, including odour nuisance, breathing problems, impacts of flies and mosquitoes, water contamination, issues due to illegal burning, and health-related problems, which was conducted using geographic information system methodologies. Besides, the Landfill satisfaction index (LSI) tool was used to assess the perception of the people residing near the landfill. Also, to statistically validate the perception of the people related to the impact of landfills on their life, gamma coefficient (y) test of Goodman-Kruskal was applied. The findings reveal that the majority of the respondent within 600m are more susceptible to various risks due to unscientific landfill. Subsequently, a large portion of the responding sample was aware of the detrimental effects of landfills on the health and environment, therefore, individuals living near the dump yard preferred to live farther away. The findings also reveal that geographical proximity has a clear relationship between respondent perception and distance to the landfill. The study concludes with a discussion on how the research results may be beneficial for designing landfill sites and can be utilized by urban planners, environmentalists, and engineers.

The Impact

The results of an experimental program undertaken to evaluate the impact of pore fluid salinity on the hydromechanical performance of light and dense backfill materials are presented. Light and dense backfills are engineered barrier materials that are being examined in the Canadian concept for storage of spent fuel in a deep geological repository. The current research investigates the impact of pore fluid chemistry on the swelling, compressibility, stiffness, and hydraulic conductivity parameters of light and dense backfills that are required as material parameters for analysis and design. In these tests, pore fluid chemistry was selected to represent groundwater within potential host units including granite and limestone rock. Results show that the performance of light backfill is significantly affected by changes in pore fluid chemistry. The swell potential of light backfill decreases with increasing salinity of the solution. The hydraulic conductivity decreases with increasing effective montmorillonite dry density and specimens saturated with saline solution have higher hydraulic conductivity than those saturated with distilled water. Conversely, the behaviour of dense backfill is governed mainly by the crushed granite component and therefore changes to the pore fluid chemistry have relatively little effect. Results of dense backfill tests confirm the material performance as a sealing material.
