CHAPTER ONE
INTRODUCTION
1.1
BACKGROUND INFORMATION
Natural water whether surface ground water, river, ocean or lakes
contains variety of micro-organisms. The sanitary quality of drinking water is
affected by both variety and number of micro-organisms. The sanitary quality
of drinking water is affected by both Variety and number of micro-organisms
available.
River is fit for drinking if its does not contain any micro-organism that
are pathogenic to man. The WHO (1958) published the international standard
for drinking water, in it water for consumption should be free from pathogenic
organisms.
According to Howel (1994). He defined bacterial gience examination of
river as the process of identification of bacteria organisms in the river. The
bacteria organisms are pathogenic to man when they drink it. Some of the
causative agents are singella dysenterae, vibro cholera, Salmonella Typhi, ,
Salmonella Paratyphi. Etc.

1.2
AIM AND OBJECTIVES OF THE STUDY
The aim of the study is to examine the micro-organisms in Idodo river.
The specific objectives of the study are:
1.3
1.
To identify the micro-organisms in the river.
2.
To isolate the pathogenic organisms in the river.
STATEMENT OF PROBLEMS
The people that are using contaminated water are prone to different
kinds of diseases. The diseases they suffered most are: dysentery, cholera,
typhoid and paratyphoid. Etc. idodo river is likely to be contaminated at one
time or the other due to human activities like washing, stooling, swimming etc.
These activities are possible sources of pathogenic organisms when water or
river is polluted it is no longer useful for human consumption and other
domestic uses. Polluted river therefore is source of various kinds of health
hazard.
1.4
HYPOTHESIS
H.O The river contains pathogenic micro-organisms.
8
H.I
The river do not contain pathogenic micro-organisms
5.1
SIGNIFICANCE OF THE STUDY
Evaluation of micro-organisms from river sensitizing people on the beset
way to dispose wastes so as to avoid communicable diseases that are caused by
pathogenic organisms.
To make sure that, the river is suitable for whatever it is selected for, like
domestic use, cooking and washing.
1.6
LIMITATION OF THE STUDY
Only Idodo river in Enugu metropolism is chosen for this work due to
time constraint and financial setback.
