Quantification of the non-linear relationship between arsenic (As) and physico-chemical parameters in groundwater through a Self-Organizing Map (SOM) was performed for first time Chapai-Nawabganj, Bangladesh. Due to continuous assessment quality, spatial distribution As with associated elements observed aerial extent contaminated groundwater. The results exhibited that 57 % 31 samples (n = 35) exceeded allowable limit according WHO recommended drinking water standard (10 μg/L) Bangladesh Drinking Water Standard (BDWS) (50 μg/L), respectively. map demonstrated higher concentration found central portion study area less amount eastern part. Whereas 83 iron (Fe) surpassed guideline (0.3 mg/L) were distributed all over except Moreover, manganese (Mn) varied from place within WHO. SOM analysis elucidated other two-dimensional planes having 49 nodes (7 × 7), which incorporated Spearman's correlation coefficient quantified positive among As, Mn Ca, negative Fe, EC pH. In accordance human health risk also explained terms non-carcinogenic carcinogenic risk. Health hazard (HQ) values threshold value adults oral route, implied potential risk, while 63 cancer (CR) than indicating considerable zone residents area. This provides information planners formulating effective resources management minimizing sustainably.
