Status of Arsenic Test and Exposure to Arsenic-contaminated Tubewell Water: A Population-based Study in Southern Bangladesh

This study explores the status of arsenic test of tubewell and exposures to arsenic-contaminated tubewell water in the arsenic prone southern Bangladesh. Through a survey of 6,593 households, a total of 3,812 tubewells were sampled at baseline (2006/07) and 3,591 at midline (2009). Households were selected through multi-stage sampling procedure where each sub-district was considered as a cluster. Findings reveal that proportion of unmarked (to identify presence of arsenic) tubewells increased from 80% at baseline to 90% at midline (p<0.001). Proportion of tested tubewells was significantly decreased from 75% at baseline to 69% at midline (p<0.001).

According to the Climate Change Vulnerability Index 2015, Bangladesh is the first and most at risk country to the impacts of climate change. Aggravating climate conditions threaten crop production and now barely allow for small farmers living in the districts along the coast to live decently from their agricultural activities, which represent the main livelihoods in the area.
