CHAPTER 1 INTRODUCTION Main Report Chapter 1 Introduction Main Report CHAPTER 1 INTRODUCTION 1.1 Background of the Study The Peoples Republic of Bangladesh has a population of 123 million (as of June 1996) and a per capita GDP (Fiscal Year 1994/1995) of US$ 235.00. Of the 48 nations categorized as LLDC, Bangladesh is the most heavily populated. Even after gaining independence, the nation repeatedly suffers from floods, cyclones, etc.; 1/3 of the nation is inundated every year. Shortage in almost all sectors (e.g. development funds, infrastructure, human resources, natural resources, etc.) also leaves both urban and rural regions very underdeveloped. The supply of safe drinking water is an issue of significant importance to Bangladesh. Since its independence, the majority of the population use surface water (rivers, ponds, etc.) leading to rampancy in water-borne diseases. The combined efforts of UNICEF, WHO, donor countries and the government resulted in the construction of wells. At present, 95% of the national population depend on groundwater for their drinking water supply, consequently leading to the decline in the mortality rate caused by contagious diseases. This condition, however, was reversed in 1990 by problems concerning contamination brought about by high levels of arsenic detected in groundwater resources. Groundwater contamination by high arsenic levels was officially announced in 1993. In 1994, this was confirmed in the northwestern province of Nawabganji where arsenic poisoning was detected. In the province of Bengal, in the western region of the neighboring nation, India, groundwater contamination due to high arsenic levels has been a problem since the 1980s.
