Abstract:
Water is the most abundant substance on the earth’s surface for the survival of all known
forms of life. Next to the air we breathe, water is human kind most important substance. It is
always the vital commodity for humans. In the present study, two samples were analyzed for
some physicochemical parameters and selected metals using flame atomic absorption
spectrophotometer and flame photometer following standard methods and laboratory
procedures. The experimental procedures were set according to the international drinking water
standards set by American Public Health Association (APHA).A total of nine physicochemical
and twelve metals were analyzed in order to understand the characteristic and quality status of
the two streams. The results were compared with standards prescribed by (CES, 2013) and
(WHO, 2011, 2017). The recorded mean concentration of total iron were 0.49±0.03 mg/L (in
Tukuro) and 1.26±0.05 mg/L (in Danisa) springs which is above CES and WHO (0.3 mg/L).
Potassium 5.05±0.10 mg/L in Tukuro is higher than 1.5 mg/L set by CES and WHO. Turbidity in
Tukuro sample site (5.52±0.42 NTU) is above 5 NTU (CES and WHO). The PH value in Danisa
was 6.05±0.14 unit which was below 6.5 – 8.5 set by WHO and CES. Dissolved oxygen in
Tukuro (11.14±0.10 mg/L) and in Danisa water sample (14.09±0.20 mg/L) which is above
permissible limits of ECS and WHO (5.0 – 7.0 mg/L). All the rest listed parameters above were
within the recommended permissible limits of CES and WHO standards that agreed with
drinking water quality level. The concentrations of each parameter among the selected sites
were significantly different (ANOVA, p ≤ 0.05). Based on the current study result, the two
protected spring water are almost safe for drinking purposes even though some of the
parameters are slightly above the CES and WHO permissible limits.
