This study evaluates the comparative study of selected heavy metal and
physico-chemical characteristics in borehole water, well water, bottled
(table) water and sachet water in selected places around Apata-Adabeji,
Ibadan, Oyo state. Nine (9) samples were analyzed which are three (3)
bottled (table) water samples (A-C), two (2) sachet water samples (DE),
two (2) well water samples (F-G) and two (2) borehole water samples
(H-I). Water qualities parameters examined were pH, Alkalinity,
Conductivity, Total hardness, Total Dissolve Solid (TDS) and some
metals; Calcium (Ca), Phosphate (P), Lead (Pb).Metal concentration
analysis was done with the aid of Atomic Absorption Spectrophotometer
(AAS) and the physicochemical parameters were measured using
standard method. The result was compared against drinking water
quality acceptable standard. The study showed selected physicochemical
and heavy metals analysis are in accordance with permissible standards
of World Health Organization (WHO) and Standard Organization of
Nigeria (SON), but having some heavy metals analyzed in the water
samples below WHO and SON standard while some water samples are
above standard limit of WHO and SON in water samples of Pb in sample
(A), Fe in sample H and Mn in sample F. Lead and Manganese were not
detected (ND) in samples B, C, E. Zinc ranged from (0.008-0.035), Lead
ranged from (0.02-0.044), Iron ranged from (0.002-0.034), manganese
ranged from (0.001-0.059). The result showed selected heavy metals and
physicochemical parameters analyzed in all the water samples except for
Pb in sample A, Fe in sample H and Mn in sample F was not
contaminated and within permissible limit, therefore water is safe for
use.
