In Bhoori creek area people are using hand pump for drinking water, hence the
sample was collected to find the drinking water quality parameters. The results of
the tube well water show that the water quality is not very good, as it has the
influence of the sea. The TDS and the salt concentration (calcium, magnesium
chlorides and) were found exceeding the WHO drinking water quality standards.
The nickel and phenol levels were also violating the WHO guidelines. Other
parameters as reflected in Table 26 are within WHO safe limits.
