Study On Leachate And Its Effects On Soil Properties

Abstract

The resources of earth are supporting the man kind, but various actions of man increases the generation of waste causing a huge solid waste, presently which is a third pollution in world –wide. The gradual decomposition of solid waste, includes various bye-products and soluble materials like nutrients, pesticides, chemicals are leaching into the soil and causing a soil pollution as well as ground water pollution. The leaching liquid known as Leachate, percolates into the layers of soil and effects the Various Geo-technical properties. The study confines to identify the effects of the leachate on soil properties and also to study the variations in treating the leachate by Recirculation method to decrease the concentrations levels. By collecting the waste, an artificial dump yard is created and water is added to the waste for formation of leachate. A setup is made, the leachate is treated by one of the Leachate treatment methods the method of recirculation. Leachate is collected and parameters pH, BOD, COD, Alkalinity, Sulphates, Nitrates, Conductivity, Total hardness, Total Dissolved Solids, Total Suspended Solids, Chlorides of leachate are tested in before and after the recirculation process. The soil property at the site was observed before and after leachate formation. Also the recirculated leachate is sprinkled in the site, soil properties was tested. For soil engineering properties, geo-synthetics like geo-membranes can be used at the dumping site to reduce the effect of leachate on soil properties.
