Water quality indices (WQI) were introduced aiming at giving a single value to the water quality of a source, thus reducing great amount of parameters into a simpler expression . In this book, an attempt has been made to devise a methodology to analyse various water quality parameters and then integrate them with WQI and Geographic Information System (GIS) for an effective interpretation of the quality status of groundwater by taking Delhi as a case study. Physical and chemical analysis of groundwater of Delhi was conducted and results interpreted using WQI and finally translated in...

Various IT enable services have emerged over last decades and today are commonly known as call centers, the BPOs, the KPOs, the LPOs and so on. The Carbon footprinting methodology has played a crucial role in encouraging companies to take the steps in Carbon Emissions measurement and management path. The GHG Protocol and ISO 14064 are the most widely used international accounting tool for measuring and managing carbon footprints. The Project details a case study of an IT company where carbon footprinting was undertaken to provide a safer and healthier work environment to all the stake...

Road-side dust originates from interaction of solid, liquid and gaseous materials produced from different sources. Street dusts often contain elevated concentrations of a range of toxic elements. The present study area lies in the coal mining dominated regions of Dhanbad district in eastern part of the Jharkhand state. Sampling of the road-side dusts was carried out along the roads of Jharia Coalfield. The physico-chemical parameters: particle size distribution, texture analysis, bulk density, particle density, total porosity, maximum water holding capacity, moisture content, volume...
