The surface and subterranean waters of Hazaribagh industrial area, the western part of Dhaka city of Bangladesh are heavily contaminated with chromium, inorganic and organic matters. In this study, exposure assessment of chromium, pH value, alkalinity, calcium and dissolved organic carbon in tannery effluents, surface water and groundwater has been done. The samples were collected from ten different sites in two seasons (spring and winter) according to a well-planned monitoring scheme that can represent the entire area and the instant analysis was done. The pH values of waste water flowing through main outflows and groundwater varied from 8.90 to 11.00 that is higher than the acceptable limit proposed by Bangladesh drinking water standard, very harmful for aquatic animals and unfavorable for microbiological growth for waste treatment. The calcium content of the samples (560.0-1600.0ppm) was also very high to disrupt sewerage system by deposition of calcium carbonate inside it. The high content of dissolved organic carbon (DOC) from 338.98 to 361.13ppm is depleting the dissolved oxygen (DO) in the river Buriganga making the water ecosystem uninhabitable for fish. The chromium content of the chrome tan liquor and waste water ranged from 5.19 to 72.80ppm. This higher concentration can interfere with biological oxidation by tying up the enzymes essentially required for microbial growth and exceeded all of the national and international standards for safe disposal and drinking. The chromium concentration in surface water (5.19ppm) on the low-lying lands discharged from main outflows showed identical value with that of groundwater (5.19ppm) contributing to dietary intake. The daily intake of chromium, 377.45μg/kg/d for the residents of that area, that is higher than maximum limits proposed by USA, NRC (0.71-2.90μg/kg/d) and FDA (120.00μg/d), arises health concern among the population and they are at risk of health hazards.
