| Abstract | This study looked into the risk of groundwater pollution from
on-site sanitation in Dhaka, Bangladesh. A sizable proportion of the
city population do not have access to adequate water supply. Groundwater
is the major source of potable water for domestic use. Safe excreta
disposal facilities are also very limited in the area.
This study also evaluated the extent of groundwater pollution
in relation ' to on-site sanitation systems in the project area.
Groundwater quality was monitored at selected points for specified time
at regular interval. Later the data were analyzed for identifying the
probable sources of the pollutants; and investigating the factors
controlling their movement in the soil-water system. In addition, the
present water supply, sanitation, and health status of the area has also
been reviewed.
The results from t he experiments indicated the presence of
pollutants of fecal origin, such as fecal coliform, bacteriophage, and
nitrate, in almost all the samples analyzed. The extensive use of
unsewered disposal system has been identified as the major source of
pollutants. The hydrogeologic condition was found to be unsuitable for
the traditional methods of on-site sanitation. Routine monitoring and
detailed study has to be carried out for having a c l ear view of the
potential of groundwater pollution by on-site sanitation facilities in
the study area. |
