Abstract
In Ethiopia, despite the progress that has been made to advance water supply access and the health status of the population in the last one and half decades, communicable diseases account for about 60-80% of the health problems. The existing burden of diseases is preventable and a considerable proportion is directly related to using unsafe water.
Poor solid waste management systems from urban municipal dumpsites into surface and groundwater sources can be harmful to the urban population who use these water sources. Gradual accumulations of contaminants in the water sources can result in high loads of pollutants that are potentially toxic to the users. In Mizan Aman Town River Gechab, Cosakol, Shonga, Petrous, and Nimbus drain through the town and improved groundwater wells are the main sources of potable water for most residents. This study was conducted from December 2020 to April 2021, intending Assessment of Municipal Solid Waste Generation, Composition and Effects of Dumping Site on Water Quality at Mizan-Aman Town
Bench Maji zone, SNNPR, Ethiopia
A random research design was used in the study. The solid waste generation rate, composition, and disposal practices were assessed. The water quality of water resources around dumping sites was assessed. Water samples were collected from wells and the surface water during both the dry and the rainy seasons. The results that were found in the research were used as baseline information for a government institution to provide methods of managing solid waste disposal systems and to plan efficient collection and management of solid waste from the source of generation to disposal site.
The Physic-chemical parameters measured show that other than the pH, total hardness, electrical conductivity, TDS, iron, fluoride odor, and taste, all other concentration values exceeded the Ethiopia minister of water and irrigation guidelines for drinking water and WHO guideline. The presence of a high load of bacteria in both surface and groundwater samples means that leachate is altering the water quality of water in the vicinity of the dumpsite. The bacteriological concentration of water from all sampling sites exceeded the Ethiopian minister of water and irrigation standards. Hence the surface and sub-surface water in the neighborhood of the dumpsite presents a significant threat to public health.
