On this earth due to rapid industrialization for achieving highest growth rate Man is continuously over exploiting the natural resources without taking care of the future generations. Industries does not treat their effluents before discharging it in the rivers or underground which contaminates the water at below. Contaminants like hexavalent chromium which are highly cancerous and damages various vital organs gets assimilated into the soil and water table thereby creating number of diseases which are beyond treatment too, thus people lose their lives. Hence analysis of Underground Water to test its fitness for human consumption by performing all the standard physio-chemical tests on various drinking water parameters and to test the presence and removal of chromium and other toxic metals in it by using biosorption properties of various agents gained attention. Till now Studies conducted includes the effect of contact time, temperature, solution pH, elution studies, adsorbent dosage and effect of metal concentration by using isotherms along-with Field Emission Scanning Electron Microscope, Atomic Absorption Spectroscopy and Fourier Transform Infrared Spectroscopy on water sample of selected location with Recombinant DNA Technology and various dimensions of Biotechnology. . However More methods and techniques can be conducted to test the toxic level of chromium in environment using various bioremediation agents for its removal. Many researches are going on to provide natural remediation methods which are useful for humans for easy removal of contaminants from our Environment. So it becomes necessary to analyze sources of heavy metals, development of new techniques, status across India along river Ganga, health problems due to heavy metal toxicities, drugs required to treat heavy metal poisoning, biological agents as cheap source of bioremediation when compared to conventional remediation techniques thereby stepping ahead in the field of bioremediation to remove contaminants from environment.
