Appraisal of Heavy Metal Presence and Water Quality having Microbial Load and Associated Human Health Risk: A study on tube-well water in Nalitabari township of Sherpur district, Bangladesh

This article is based on a study aimed to determine physiochemical parameters, fecal coliform, total coliforms, heterotrophic plate count, arsenic, iron and lead of water evaluate their effects human health. Analysis was carried out tube-well collected from Nalitabari township Sherpur District in Bangladesh. The dissolved oxygen (DO), solids (TDS), salinity electrical conductivity were the ranges 4.30 7.30 ppm, 350 792 mg/l, 0.2 0.5%, 715 1,970 μS/cm. pH values slightly lesser or more than permissible value. Due vicinity latrines, 17 tube-wells’ contaminated by coliforms. highest count 7.5×103 cfu/ml ward-8 town. Eschericia coli Vibrio cholerae identified ratio 30.56% 18.06%, respectively, water, resulting into diarrhea among children. About 6.94% with arsenic. 3.25% 4.5% respondents suffering skin diseases headache, respectively.
