This book is a compilation of the articles covered in the Training Course on “Facing the Challenges of Climate Change: Issues, Impacts and Adaptation Strategies for Bangladesh with focus on Water and Waste Management” for the people concerned about the threats and challenges posed by Climate Change.

Contamination of groundwater with arsenic is considered as a major challenge in the water supply sector of Bangladesh. ITN-BUET has conducted a number of researches on arsenic issue. In continuation of ITN-BUET initiatives, a research on “Leaching of Arsenic from Wastes of Arsenic Removal Systems” was conducted by ITN-BUET during 2001 to 2002. This publication is the outcome of this initiative.

ITN-BUET has developed a Quality Assurance System for the training programs by which a balanced evaluation of a training program can be carried out. This document is the manual of that QA System model.

This publication aims to update the knowledge base concerning all aspects of arsenic contamination, with a particular focus on Bangladesh. Major issues, including hydrogeology, water and soil contamination, food safety, health implications, social consequences, as well as analytical aspects including the chemistry and fate of arsenic in the environment, are discussed extensively within the context of Bangladesh.

This textbook has been developed with proper balance of ‘software’ i.e., socio-cultural and economic aspects and ‘hardware’ i.e., technical aspects, and with special attention to gender issue, including experiences in Bangladesh.

This publication includes a compilation of selected papers presented at International Symposium on Environmental Sustainability (ISES) 2006 along with invited keynote papers. The papers cover a wide range of issues including environmental sustainability, water supply and sanitation, transportation…

The purpose of the risk assessment was to quantify the health risks associated with different arsenic mitigation options. In providing alternative water supplies, it is important to be aware that users may be exposed to other hazards such as pathogens. Risk substitution in arsenic mitigation should always… … …

The research focused on development of a community based Arsenic-Iron Removal Unit (AIRU) adopting the technique of adsorption and co-precipitation of arsenic onto the flocs of ferric hydroxide, making use of the naturally occurring iron of groundwater. The operation and maintenance of the developed AIRU are simpler and more users friendly in comparison to the previously developed community based water treatment units. Number of beneficiaries and water consumption was increased by about 10 folds after the installation of the AIRU.

This book is a compilation of articles on contemporary environmental issues and challenges selected from papers presented at the International Symposium on Environmental Management, ISEM 2004.
