Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrations of Cl-, NO3-, SO42-, NH4+ were found to be in considerable levels in the groundwater samples particularly near to the landfill sites, likely indicating that groundwater quality is being significantly affected by leachate percolation. Further they were proved to be the tracers for groundwater contamination near Semur and Vendipalayam dumpyards. The presence of contaminants in groundwater particularly near the landfill sites warns its quality and thus renders the associated aquifer unreliable for domestic water supply and other uses. Although some remedial measures are suggested to reduce further groundwater contamination via leachate percolation, the present study demands for the proper management of waste in Erode city.
Higher education plays an important part in every country existence as it provides highly trained experts for future growth and prosperity for this country. Today, almost all institutions of higher education deliver programs that incorporate digital media into an online environment to provide versatile learning opportunities, regardless of time and location. Thus, the internationalization of higher education tends to be a double-edged trend, which causes growing cooperation and rivalry between countries and institutional providers. Internationalization takes many forms, including co-learning courses and degrees, online classes, professorship exchanges, recruitment of students and joint research, collaborative research projects and student exchanges.
