Groundwater constitutes an important source of water for drinking, agriculture and industrial production. The use of groundwater has increased significantly in the last decades due to its widespread occurrence and overall good quality. Water quality index exhibits the overall water quality at a specific location and specific time based on several water quality parameters. The objective of an index is to turn complex quality data in to information that is understandable and usable by the public. The water quality of the Kadapa town varied from excellent to good. The high value of WQI at these stations has been found to be mainly from values of fluoride, Electrical conductivity. In some of the collected samples, the concentrations of these parameters exceed the permissible limits of WHO and ISI standards. After evaluating the data of this study it is concluded that there is an instant need to take ameliorative steps in Kadapa, Badvel, Kalasapadu, Porumamilla mandals, Vemula, Vempalli of Y.S.R District to prevent the population from groundwater pollution. Measures on a groundwater-quality monitoring program are suggested for the sustainable development of this area.

The book describes the role of Geographical Information System and Remote Sensing in modeling the groundwater distribution pattern and quality in the state of Rajasthan in India. Groundwater table map of various time series (pre and post monsoon), rainfall maps and fluctuating patterns have been generated using the groundwater level data of pre and post monsoon seasons and daily rainfall datasets of Rajasthan. Further, the OCEANSAT - 2 OCM satellite data has been used for generating the Normalized Difference Vegetation Index maps. Groundwater quality maps (WQI maps) of Rajasthan have been generated using groundwater chemical data of the state. The WQI maps indicated that the groundwater quality decreases from the South-East to the North-West of the state. The safest zone is in the South-Eastern part of the study area. Various Geo-statistical techniques have been applied in generating all these maps.

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 sensitivity maps using GIS. The book delves in understanding water quality assessment and should be useful for anyone interested in groundwater quality issues from general public and students to policy makers.

Waste Water Irrigation

The Book 'Waste Water Irrigation' is an out-come of researches of about 5 years. Waste water is a great problem in developing countries like India. The waste water in India is generated through a variety of sources and its proper disposal is not an easy task. On the other hand lots of groundwater is wasted for irrigation, particularly for vegetables, which are mostly grown in the sub-urban area. Due to enormous pumping of water by the urban population in addition to the run off loss through vegetable irrigation, the water table occasionally falls abruptly in urban area, particularly during summers. In addition solanaceous vegetables are the most prominent food stuff, which is used round the year. Therefore, series of experiments were conducted through irrigating solanaceous vegetables by sewage. WQI of the sewage water and its suitability was also studied. The yield and nutrient analysis of the harvest was explored and compared to that of the crop irrigated by normal water. Satisfactory results were obtained. The book is supposed to be useful to all, involved in the researches of environment, may be from the discipline of Botany, Zoology, Geography, Biochemistry, Engineering etc.

An integrated survey based on satellite image interpretation corroborated with limited field checks were carried out with a view to delineate the ground water potential in parts of Y.S.R District district, Andhra Pradesh, South India. The interpretation of Remote Sensing data & GIS in conjunction with conventional data and sufficient ground truth information makes it possible to identify and outline various ground features such as geological structures, geomorphic features and their hydrologic characters that may serve as direct or indirect indicators of the presence of ground and surface water. In the present study, a detailed investigation was carried out with an objective of identifying the index of groundwater by using Water Quality Index (WQI) method. Prominent water quality parameters controlling the hydrochemical evolution of aquifer system was studied.
