Abstract:
Approximately 1.1 billion people in the world lack access to safe drinking water. As
a result 1.8 million people mostly in developing countries, and 90% of whom are
children under 5, die every year from diarrheal diseases such as including cholera.
This study was carried out with the objective of evaluating access to safe drinking
water and the perceived incidence of water-borne diseases in North Masaba
District, Kenya. Two samples were collected from each household, one sample of
drinking water after treatment and another sample of water directly from the
source. From each sample, the population of Total Thermotolerant Coliforms was
determined. The results were recorded as the number of Colony Forming Units
(CFU/100 ml). Only 49% of the households were found to consume drinking water
that is considered by WHO to be of reasonably good quality while 16% of the
households consumed water unsuited for human consumption. For the turbidity
tests, 57% of the households achieved the WHO recommended standard of less
than 5 NTU. It was noted that while many households have access to improved
water sources, and while these sources provide drinking water that is less
contaminated than unimproved sources, the quality of water from these sources
does not meet WHO standards. This would explain the high percentage of people
(34%) reporting incidence of water-borne diseases in the household. There is
therefore need for sensitizing the 25% of the households that do not carry out
point of use (POU) intervention to start doing so before consuming the water.
There is also need for more research to establish why some of the POU
interventions fail to provide safe water even though it is known that such methods
are very effective in microbial decontamination.
