| 概要 |
This article analyzes how arsenic mitigation activities are effective in matters of acquisition of safe drinking water. A survey was conducted concerning drinking water sources and arsenic contaminati...on in a total of 2006 households in two arsenic contaminated villages in Bangladesh. The first village (1199 households) had a high percentage (67%) of safe drinking water usage, and the second (807 households) had a low percentage (15%). This result arises from the difference in the type of safe water sources in the respective villages. Two types of drinking water sources, such as safe water devices and deep tubewell, were used in the first village (high usage of safe drinking water); in contrast, these alternative water sources were not generally used in the second village, and arsenic-free shallow tubewells were mainly used for safe drinking water. The high percentage use of safe drinking water in the first village was related to newly constructed alternative water sources. Residents in this village are relatively wealthy and the village is located at the intersection of important national and county roads. Furthermore, private funding and residents' social connections have led to the construction of more safe water sources and their maintenance.続きを見る
