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.

Abstract The study area (Green-Belt Project) locates in AL-Najaf Governorate in the coordinates (44o 10' 0"E & 44o 20' 0"E) and (32o 5' 0"N & 32o 15' 0"N). The study area has covering an area of about (90) km2, which contains many geological formations and represents part of Najaf-Karbala plateau. The project relies on ground water as sources of irrigation. The aim of this study is to evaluate the quality of ground water in the project area for irrigation and suitability to use in potable purposes. Directorate of agriculture in cooperation with Directorate of wells of Al-Najaf Al-Ashraf implemented five wells which is used as sources of irrigation in this project that identified as GFW1, 2, 3, 4 and 5 , respectively in this study. GFW4 and 5 are locate in semi confined Dammam formation and deeper then GFW1, 2 and 3 which located in unconfined Dibdiba. Eleven parameters as: pH, electrical conductivity, EC, total dissolved solids, TDS, sulfate ion, SO4-2, oil & grease, O&G, cadmium, Cd, lead, Pb, chromium, Cr, iron, Fe, copper, Cu, and zinc, Zn have been selected to determine water quality index (WQI) for irrigation and potable purposes according to maximum levels of standards
