Heavy Metals Distribution and Contamination in Groundwater of the South Eastern Coastal Area of Bangladesh

Groundwater provides the largest source of usable water storage in Bangladesh. samples have been analyzed for Fe, Mn, Zn, Ni, Cr, Cu, Cd, Pb, and Co using atomic absorption spectrophotometer to evaluate heavy metal distribution contamination level at southeastern coastal area Heavy metals are range Fe (490–4710 µg/L), Mn (13–1970 Zn (70–550 Ni (42–255 Cr (25–133 Cu (34–95 Cd (7–26 Pb (0–20 (43–141 µg/L). The mean concentration exceeded Bangladesh standards drinking water. Application Pearson correlation, principal component analysis (PCA), cluster (CA) hierarchical (HCA) indicate that groundwater study influenced by both geogenic anthropogenic sources metals. evaluation index (HEI), degree (Cd) pollution (HPI) employed overall estimating 40, 27 60% respectively exhibit medium pollution.
