This study documents the response of 6500 rural households in a 25 km(2) area of Bangladesh to interventions intended to reduce their exposure to arsenic contained in well water. The interventions included public education, posting test results for arsenic on the wells, and installing 50 community wells. Sixty-five percent of respondents from the subset of 3410 unsafe wells changed their source of drinking water, often to new and untested wells. Only 15% of respondents from the subset of safe wells changed their source, indicating that health concerns motivated the changes. The geo-referenced data indicate that distance to the nearest safe well also influenced household responses.
本研究记录了孟加拉国一个25平方公里区域内6500户农村家庭对旨在减少其接触井水中砷的干预措施的反应。这些干预措施包括公共教育、在井口张贴砷检测结果以及安装50口社区水井。在3410口不安全水井子集中，65%的受访者改变了饮用水源，通常是改用新的且未经检测的水井。在安全水井子集中，只有15%的受访者改变了水源，这表明健康担忧促使了这些改变。地理参考数据表明，到最近安全水井的距离也影响了家庭的反应。
