Abstract :
The ease of accessing surface water bodies has
made them susceptible to contamination especially by
anthropogenic activities. Oguta Lake is one of such
endangered surface water bodies, which is located
between latitudes 050
40' – 050
44'N and longitudes 060
46' – 060
50'E. Twenty (20) samples of water and
sediments were collected over two seasons and these
samples were analyzed for physicochemical and
microbial parameters using standard methods. The
result of the physicochemical analysis for the water and
sediment samples shows that most parameters were
within the WHO acceptable limits in both seasons.
However, phosphate, mercury and lead, were observed
to be above the acceptable limits in the water while iron,
lead and phosphate were observed to be above the
acceptable limit in the sediment. Microbial analysis for
total coliform, faecal coliform and total bacterial count
in the water and sediments were also carried out and
the results show that the total coliform and total
bacterial count exceeded the value of 10cfu/ml and
102
cfu/ml set by Standard Organization of Nigeria and
World Health Organization respectively in most of the
samples while indications of feacal contamination was
observed in 50% of the analyzed water samples and
feacal coliform count in 100% of the sediment samples
were too few to count.
