Mn, Fe, Cd and Pb levels in most of the water samples exceed the Bangladesh and international standards. The heavy metal pollution index (HPI), heavy metal evaluation index (HEI) and degree of contamination (Cd) schemes indicate that the mine drainage/irrigation waters and the adjoining groundwaters are highly contaminated. The groundwater system in the vicinity of the coal mine site is also heavily polluted by anthropogenic sources. The pollution status of irrigation and drinking water systems in the study area are of great environmental and health concerns. http://pubs.sciepub.com/ajwr/5/5/2/ajwr-5-5-2.pdf heavy metal heavy metal pollution index heavy metal evaluation index degree of contamination Barapukuria coal mine
