孟加拉国沿海地区一直面临着地表水和地下水含盐量不断增加的问题。这项研究提供了孟加拉国东南部沿海地区问题的大致范围，使用不太准确，但成本较低的盐度测量设备，使当地人民能够评估情况。2016年旱季期间，从2月中旬到5月中旬，雇用了10名当地妇女每周监测10口管井，每口管井监测10口威尔斯。利用地理信息系统和时间序列聚类分析方法，对研究区盐度的空间分布和季节变化进行了可视化研究。此外，还询问了管井使用者日常饮食中的盐摄入量。三分之一的受监测的管威尔斯被发现含有超过世界卫生组织建议的味道可容忍水平的钠。然而，所有受监测管井威尔斯的平均盐度水平要低得多。含盐量的高低取决于威尔斯的深度，而不是管井的位置或海拔高度，而那些深度超过200米的管井可能是无盐的。饮食调查的结果显示，较富裕的家庭在日常饮食中倾向于使用更多的盐，但与此同时，他们倾向于使用更深的威尔斯井，这些井不太可能含有高水平的钠。
Coastal areas of Bangladesh have been facing increasing salinity of surface water and groundwater. This study provides the approximate scope of the problem in a coastal area of southeastern Bangladesh by using less-accurate, but lower-cost salinity measuring devices that enable local people to assess the situation. Ten local women were employed to monitor 10 tube wells each on a weekly basis, from mid-February to mid-May, during the 2016 dry season. Geographical Information System and time series clustering were used to visualize the spatial distribution and seasonal change of the salinity levels. In addition, the tube well users were asked about the salt consumption in their daily diet. One-third of the monitored tube wells were found to contain more sodium than the tolerable level in terms of taste suggested by the World Health Organization. However, the mean salinity level across all monitored tube wells was much lower. The salinity level varied depending on the depth of the tube wells rather than their locations or altitudes, and those deeper than 200 m were likely to be salt free. The results of the diet survey showed that wealthier households tended to use more salt in their daily diets, but at the same time they tended to have deeper tube wells that are less likely to contain high levels of sodium.
