Hazard Analysis Of Domestic Water Self Supply From Handdug Well In Asin Community Of Ikole Local Government Area

ABSTRACT

Domestic water supply is a daily necessity and key factor in human health and well-being. Without water, life cannot be sustained and lack of access to adequate water supplies leads to wide spread of diseases with children bearing the greatest health burden associated with poor water quality and sanitation. Drinking water is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Asin-Ekiti community is situated in Ikole-ekiti, Ekiti, Nigeria It is located in south-western Nigeria on longitude7° 47' O" North and latitude 5° 31' O" East. The predominant mother tongue spoken in Asin-ekiti of Ikole, Ekiti State is Yoruba. It has an area of 321 km2 and a population of 168,436 at the 2006 census. Asin-Ekiti of Ikole Local Government Area is situated in the deciduous forest area of the State. This research work focused on hazard analysis of domestic water self-supply from hand-dug well in Asin-Ekiti community of Ikole LGA. Also, the water sources under study in Asin-Ekiti community were located and samples were randomly · collected from twenty hand-dug well with adequate precaution from each of the sources and tested for the physical, chemical and bacteriological parameters thereby monitoring the water quality of the samples. Results afterward showed that not all water samples collected met the standards for drinking water. All Physical parameters met the recommended standard but for the chemical parameters, the pHof samples 1,2,3,4,5,10,15 and 16 were slightly below recommended standard while Magnesium content of all samples were above NSDWQ recommended limit but within WHO recommended limit. The Total Coliform count of Sample 1,2 and 3 were within recommended limit but all the remaining samples were above recommended limit which show evidence of contamination with moderate risk and can be decontaminated by chlorination. Results from the Hazard Analysis showed that three water sources monitored met all the requirements for drinking water quality, corrective measured were proffered and no flooding around all water source. It is recommended that regular monitoring of domestic water quality should be maintained for all the domestic water sources.
