ABSTRACT
This work was aimed at assessing
microbial coal of Idodo river in Enugu state Nigeria. The samples of river was obtained from the
arc of low activity, and a place where human activities are very high. The samples were collected very early in the
morning and afternoon. They were
examined to determined the bacterial organisms that are pathogenic to man when
they drink it from the samples were inoculated into media. Nutrient agar and macconkey agar media and
incubate at the temperature range (350c - 370c). The following organisms were isolated. Streptococci faecalis  clostridium Perfringens,
Rhodococcis corphilus, Bifidobacteria, salmonella spp. The study shows that appropriate care should
be taken to protect the river from being contaminated by these organisms. The
quantity of pathogenic organisms collected were more in the afternoon.

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.
To identify the micro-organisms in the river.
2.
To isolate the pathogenic organisms in the river.
1.3 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.
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.
