Physical, Chemical and Biological Parameters in Well Waters of Karachi and Their Health Impacts

摘要

The study was carried-out to assess the well water quality, which were collected from different areas in Karachi. For this purpose thirteen different parameters were tested for each and every sample collected from different locations in Karachi. These parameters were pH, alkalinity, total dissolved solids, hardness and others. By conducting these tests it was found that some parameters fall within the permissible limit as suggested by World Health Organization, but some parameters were found to be in very high concentrations. Overall, it was found that the most of the water, collected from different locations in Karachi, was not suitable for domestic as well s for industrial purpose.
