    Abstract
    The immensity of the global safe water crisis is underrated, though for decades’ water has been contemplated as the most imperative natural finite resources that is required for human development and existence. The accessibility and availability of fresh clean water does not only play a crucial role in economic development and social welfare but also a help to raise awareness regarding potential risk of pathogens and heavy metals from natural water reservoir. Escherichia coli, Enterobacter, Salmonella and Shigella are one of the major causes of gastroenteritis worldwide. Due to the presence of related genotypic strains, it is reported that natural water bodies can be served as reservoir for the dissemination of these strains in environment. Besides, human are exposed to harmful heavy metals in several ways ranging from consumption of contaminated food and water as well as exposure to polluted air droplets. Nevertheless, innumerable studies have been carried out over the years to assess the impact of disease causing organisms in water quality management, our scientific research showed renewed interest to standardize and evaluate the qualitative as well as quantitative assessment of water quality. In such instance the focus of this experiment is to identify the presence of Escherichia coli., Enterobacter, Salmonella and Shigella, along with presence of toxic chemicals like Lead (Pb) and Chromium (Cr). The presence of high concentration of the heavy metals in water may posture substantial health risks along with the impact caused by Escherichia coli, Enterobacter, Salmonella and Shigella. So constant checking of both chemical and biological quality of natural water sources is highly recommended. The literature reported here focused on a parallel assessment of the levels of the toxic chemicals like Lead and Chromium in distinct locations Tongi and Tejgaon Industrial Zone, Dhaka city within the period of May to December, 2019 along with the presence of Escherichia coli., Enterobacter, Salmonella and Shigella. Finally, the results portrayed that the in presence of harmful chemicals organisms like Escherichia coli., Enterobacter, Salmonella and Shigella can sustain for a longer time in water which can show long term impact on human and environment that is yet to be studied at in vivo condition considering the fact how this factors will be associated with human exposure to wastewater in the industrial zone.
