WHO recommended turbidity value for drinking
water as 5NTU? In present study 5 tube well’s samples,
7 distribution network samples and 9 storage tanks
water samples were found to cross the permissible
limits of WHO. Akoto and Adiyiah (2007) undertook a
study on chemical analysis of drinking water of Brong
Ahafo areas (Ghana). Total 15 samples were collected,
10 from surface water and 5 from ground water.
Collected water samples were analyzed for pH,
turbidity and EC etc. Study results revealed that EC of
the surface water samples below the permissible limits,
pH values within the permissible limits and turbidity
values cross the permissible limits of WHO. Water
samples collected from ground sources, 60% samples
pH values were found above the permissible limits,
40% samples turbidity values cross the permissible
limits and EC of all the samples were found above the
recommended limits of WHO.
