Abstract | The pattern of groundwater arsenic (As) concentrations in Bangladesh is thought to be highly variable with time. To assess the changing pattern of As concentrations over time for developing a sustainable and affordable testing protocol for As, water from 246 sample tube wells of Jhikargachha, southwest Bangladesh, was analyzed using atomic absorption spectrophotometry (AAS) at two different time periods. The local hydrogeology and its relationship with As concentrations were also analyzed. Statistical analysis illustrates relationships between As in groundwater with different well parameters and aquifer properties. A positive correlation was observed between well depth and percentage of As-contaminated wells (R = 0.89). Similarly, the percentage of contaminated wells increased with grain size of the aquifer sediments, with a maximum percentage of |
