Chemical Assessment of Cadmium in the Groundwater of Saharsa District, Bihar

Now a days water pollution has become one of the most common phenomenon and the consumption of polluted water has become the fate of the people. People are suffering from many types of diseases due to consumption of polluted water and hence to create awareness and to avoid these diseases, regular monitoring of water quality is essential. Present paper reports the result of chemical assessment of cadmium in the groundwater of Saharsa District, Bihar which is situated at latitude 25035’–26028’N and longitude 86018’–86051’ E. All the ten community development blocks of Saharsa district have been selected as sampling sites and from each block two samples either from well or tube well, on the basis of availability of functioning well or tube-well, have been collected for analysis. Thus, all together twenty samples were collected for pre- and post- monsoon seasons respectively in the year 2022. These samples were analyzed. The concentration of Cadmium (Cd) was found to be ranged between0.046 ppm to 0.073 ppm for pre-monsoon and 0.044 ppm to 0.068 ppm for post-monsoon season, and its average values was between 0.044 ppm to 0.070 ppm. The acceptable and allowable maximum limits prescribed by USPH and WHO respectively are same i.e. 0.01 ppm. Thus all the values are much higher than the maximum limit.
