ABSTRACT
Water is
an essential resource
for sustainable life
and environment which
is meant to be
available in abundance
and free gift of
nature. Good drinking water
quality is essential for our well-being irrespective of its source. One of the most important crises of the 21st
century is the availability of drinking water, a resource that is essential for
our survival and growth. This study is aimed at assessing and determining the
trace elements in Issele-Mkpitime Lake, and the most relevant controls on the
water quality. Trace elements may come from natural sources, leached from rock,
and soils according to their geochemical mobility or anthropogenic sources as a
result of human, land occupation and industrial pollution. Depending on their
solubility, these metals may eventually become associated with suspended
particulate matter and or accumulate in the bottom sediments. The total concentrations
of sample site of trace elements such as zinc, lead, iron, sodium, manganese,
Nickel, cadmium, copper, vanadium and others were determined using atomic
absorption spectrophotometry method. The result of geochemical analysis carried
out for the selected trace elements in Issele-Mkpitime Lake shows that sodium
(Na) has the average concentration of 6.50(mg/l) which is above the WHO (2006 -
2010) standard for drinking water which is 0.03(mg/l), Nikel (Ni) and Vanadium
(V) have the lowest concentration range of less than 0.001(mg/l) in all the
locations. Checking out the range concentration of the trace elements in water
samples from the study area shows that Ni, Cd, Zn, V, Cr have the range
concentration of less than 0.001((mg/l) in some location while Lead range
between 0.440 – 0.500 ((mg/l), Mn has 0.020((mg/l), Copper has the range
concentration of 0.400 – 0.500((mg/l), and iron has the range concentration of
0.550 – 2.550((mg/l). In comparison with WHO standard for drinking water,
elements like Na, Fe, Pb, Cr, V, falls below WHO standard for drinking water
except for elements like Cu, Cd, Zn and Mn respectively that actually fall
within the recommended limit
