This atlas provides information on the salient findings of the project entitled "Ensuring Health and Food Safety from Rapidly Expanding Wastewater Irrigation in South Asia" coordinated by the International Water Management Institute (Hyderabad office). The three year project funded by the German Federal Ministry of Economic Cooperation and Development (Bundesministerium für Wirtschaftliche Zusammenarbeit und Entwicklung - BMZ) was carried out in two countries, India and Pakistan, in collaboration with a number of international and local partners. This atlas highlights the findings from India. The atlas comprises thematic maps and their corresponding descriptions highlighting the key findings of the project. The wastewater use in agriculture described here is associated with a polluted riverine system, due to all types of city discharges. As such, it can be expected that the water quality can change considerably in different stretches of the 40 km stretch of the river, with the head end being more polluted than the tail end. Therefore in order to avoid a rigid classification, the descriptions to the maps refer to the term "(Musi) river water". In the rest of text, the term "wastewater" is used in the context of the chemical and biological attributes associated with agronomic and health risks in any given stretch of the river. The atlas was prepared as a summary document of the key findings of the project, to promote a discussion on the wastewater use in agriculture, at the dissemination workshop held in October 2008.

There is a significant imbalance between the number of publications describing potential and actual environmental and health impacts from chemically contaminated wastewater, and reports outlining concrete options to minimize the related risks where conventional wastewater treatment is not available. This gap applies more to inorganic and organic contaminants than excess salts or nutrients. This chapter outlines some of the options available that could be considered in and around the farm, looking at heavy metals, salts, excess nutrients and organic contaminants. The emphasis is placed on low-cost options applicable in developing countries. While such measures can reduce negative impacts to a certain extent, it remains crucial to ensure that hazardous chemicals are replaced in production processes; industrial wastewater is treated at source and/or separated from other wastewater streams used for irrigation purposes; and fertilizer application rates and related possible subsidies adjusted to avoid over- fertilization.

Waste acid bentonite is a byproduct from vegetable oil bleaching that is both acidic (pH <3.0) and water repellent (hydrophobic). These materials are currently disposed in landfills and are an environmental hazard due to the aforementioned properties. A study was undertaken using three different sources of waste oil bentonites collected from processing plants within the Bangkok metropolitan area. These wastes included soybean oil bentonite (SB), palm oil bentonite (PB) and rice bran oil bentonite (RB), each of which was co-composted with rice husk, rice husk ash, and chicken litter in order to eliminate their acid reactivity and hydrophobic nature. The chemical and physical characteristics of acid activated bentonites before and after bleaching and the co-composted materials after addition to a degraded light textured soil were assessed and are reported herein. The organic carbon (OC) content, pH, exchangeable cations and cation exchange capacity (CEC) of the waste oil bentonites increased significantly after the co-composting phase. In addition, the hydrophobic nature of these materials as measured using the Water Drop Penetration Test (WDPT) decreased from 10,800 seconds to 16-80 seconds after composting. Furthermore, when these composted materials were incorporated into a degraded light textured sandy soil positive impacts to soil physical attributes in terms of specific surface area, total porosity and available water content for crop growth were observed. The results from this study demonstrate the positive impact of the waste products when modified through composting on the physical and chemical properties of a light textured sandy soil.
