Abstract

The disposals of municipal solid waste (MSW) in open dumps are a widespread activity around the vicinity of urban area. When rainwater interacts with dumping yards, generate a leachate and percolates through the soil strata and after particular time they pollute the groundwater and soil in the vicinity. In view of this, assessment of soil fertility around MSW disposal site near sangamner city, Maharashtra was carried out. Soil samples (n=16) close to dumping yard and away from considerable distance (controlled samples) were collected and analyzed for parameters like pH, EC, organic carbon, available NPK and boron by using standard methods. The pH, EC, organic carbon, available NPK and boron of soil samples were found to be higher near the dumping site as compared to control samples. The pH of samples was found to be alkaline ranges from 8.1 to 8.8 while EC increases from 0.2 to 8.3 dS/m which is toxic to plants and crops in the nearby area. The percentage organic carbon lies between 0.8 and 12.2. The available NPK was varying from low to medium and boron ranges from 0.5 to 9.7 ppm in the study area. The minimum dispersion was found in pH (0.23) and higher in N (71.61) from standard deviation (SD) value. It was observed that, since the waste was disposed, a number of contaminants readily penetrate and deteriorate the soil in the area. Thus, the disposal of waste should be discouraged and waste management and treatment should be put in place for protection of soil fertility around dumping site near the Sangamner city.

Highlights

The increasing urbanization and industrialization with changing consumer habits and standards of living have been contributed to the augmentation in MSW1.The threat of environmental pollution from municipal solid waste (MSW) has been haunting the human being world since early times and is still increasing due to excessive growth in developing countries
The highest pH 8.8 was recorded at S11, which is close to MSW while the lowest pH 8.1 was recorded at S4, S5 and S15 which are the controlled soil samples away from MSW
The higher values of pH are recorded at S8, S10, S12, S13 and S14 samples which are near the vicinity of dumping yard (Table 1)

Summary

Introduction

The increasing urbanization and industrialization with changing consumer habits and standards of living have been contributed to the augmentation in MSW1.The threat of environmental pollution from MSW has been haunting the human being world since early times and is still increasing due to excessive growth in developing countries. The major cause of the pollution in the urban society is the solid wastes which are the organic and inorganic wastes generated by fast increasing production, consumption and other human activities. It is usually unwanted and which are not useful to the first user[5]. The disposal of solid waste requires large area and proper drainage of the land disposal of MSW. It causes an impact on groundwater contamination and quality of soil[9]. These heavy metals lead to severe problems since they cannot be biodegraded[13]
