Supplementary Data for "Hotspots of Dissolved Arsenic Generated from Buried Silt Layers along Fluctuating Rivers"

This is the data used to create the study that is currently under review in a peer-reviewed journal. This dataset contains groundwater chemistry data and groundwater level data across the Meghna riverbank field site near town called Nayapara in Bangladesh. Across the 131 m-wide transect oriented orthogonally to the river shoreline, three types of wells were installed: i) Drive-point piezometers (DP) (“DPa” wells (~0.5 m), “DPb” wells (~1.5 m), “DPc” wells (3 to 4.5 m)); ii) Fully screened shallow piezometers (PZ); iii) Monitoring wells (MW) wAll wells were numbered in descending order away from the river. For example, the DP well that is furthest from the river and has the shallowest depth is referred to as “DP1a”.本数据集用于支撑目前正于同行评议期刊（peer-reviewed journal）审稿中的研究工作。该数据集涵盖孟加拉国纳亚帕拉（Nayapara）镇附近梅格纳河（Meghna river）河岸野外场地的地下水化学与地下水位监测数据。本次研究沿垂直于河岸走向布设了一条宽131米的断面，共设置三类监测井：i) 打入式渗压计（Drive-point piezometers, DP）：包含埋深约0.5米的「DPa」型井、埋深约1.5米的「DPb」型井，以及埋深3至4.5米的「DPc」型井；ii) 全滤层浅层渗压计（PZ）；iii) 监测井（MW）。所有监测井均以远离河岸的方向按降序编号。例如，距离河岸最远且埋深最浅的DP井被命名为「DP1a」。
