Studienarbeit aus dem Jahr 2020 im Fachbereich VWL - Umweltökonomie, , Sprache: Deutsch, Abstract: Poor solid waste management systems from urban municipal dumpsites into surface and sub-surface water 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 Rivers are drain through the town and inter into water supply dam. This study was conducted from December 2020 to April 2021, per day Solid waste generated 66% was degradable and 34% non-degradable solid waste.
Water samples were collected from wells and the surface water during both at dry and rainy seasons. Electrical conductivity, total hardness, TDS, fluoride, Zinc, manganese, dissolved nitrate iron, phosphate all were determined using flame atomic absorption spectrometry. Faecal coliforms, total coliforms were determined by the membrane filtration method. The Physic-chemical parameters and biological parameters are measured from streams, wells and at water tap which shows other than the pH, temperature, Electrical conductivity, total hardness, TDS, iron, fluoride odor, and taste, all other concentration values are exceeded the Ethiopia minister of water and irrigation for drinking water and WHO guideline at wet season this was due to runoff at rain season and causes the water body was to polluted.
