The following conclusions were drawn from study; all
the pollutants were detected up to 200 m from pollution
source. Proximity to the wastes sites and change in season
from dry to wet period influenced the concentrations of the
water quality parameters. Most of the hand-dug well water
samples in the vicinities of pollution source and those in the
residential areas contained Pb, Cd, and coliform levels (FC
and TC) above the WHO stipulated limits for potable
water. Overwhelming high coliform pollution index of up
to 40 for wells near pollution sources relative to those in the
residential areas were computed The high coliform index,
increased metal levels and organic loads of the water
samples were indices of pollution from leachates, seepages
and run offs of the polluted environment where these wells
were located. Based on the results, the groundwater
resource, without standard treatment is unfit for drinking
and domestic uses.
It is recommended that increased and continued
combined environmental interventions, through public
health education by community based health workers,
awareness and sensitization campaigns be carried out for
improved household and community sanitation in rural
areas in the developing countries. Wells located within 50
meters from pollution source should be abandoned and
future wells should be constructed beyond 250 meters
from pollution source. Adequate solid waste disposal
method should be adopted, phasing out open dumpsites to
safeguard public health from water borne diseases.
