Study and Assessment of Impact of Heavy Metals From Leachate On Environment.
Areas near landfills have a higher probability of groundwater contamination due to the generating potential pollution source of leachate from nearby dumping site. Such contamination of groundwater leads to substantial risk of local groundwater users and to the environment. Leachate, soil, ground water and surface water sample were collected from Bellahalli landfill site, Karnataka, India. To study the possibility impact of leachate on Soil, Ground water, Surface water quality. Testing of leachate was done for the parameters including potassium, chromium, nickel, Cobalt, copper, zinc, magnesium, iron, ammonia, sodium, lead, COD, cadmium, Manganese and organic matters were determined and reported. Concentration of COD, chromium, ammonia, sodium, iron, potassium and magnesium exceeded the ISO standards of water quality for sewer water. Further testing of soil, surface water and groundwater were done for the parameters including potassium, Cobalt, magnesium, sodium, cadmium, arsenic, colour, chromium, Copper, iron, lead, manganese, odour, pH value, nickel, zinc, ammonia, COD, organic matter, chloride, TSS and TDS were determined and reported. Reports show that concentration of sodium in groundwater was slightly high according to the EPA standards of groundwater, this indicate that the Groundwater quality was less. Concentration of TDS and sodium were slightly high compared to the standards of EPA in the surface water and concentration of copper and zinc were high in soil. Near the landfill site, the presence of contamination in sample shows the quality and thus renders the use of domestic purpose. This study requires proper management of waste in the city.
