CHAPTER ONE
INTRODUCTION
Water is a liquid mineral. It consist of
two atoms of hydrogen combined with one atom of oxygen. Water is a
tasteless, odourless and colourless mobile liquid except in large volume
where it appears blue. It has a melting point of OoC (320f) and a
boiling point of 1000C (2120f). water is a basic necessity of life, in
the absence higher animals survive only but a few hours or days. It has
several uses such as washing cooking, food processing ,swimming, and
among others. Out of these uses, drinking of water seems to be the most
sensitive as it could have a direct deleterious impact on health of
human beings.
Therefore, drinking water should be potable free diseases, or toxic substance (Beren 1991) .
Water
is portable when it is colourless. Odourless, or tasteless and also
free from poisonous, corroding, staining substances as well as disease
casuiong oirganisms (Cruich 1972). The problem of providing safe and
adequate water is as old as life on earth. Water can be made unifit or
unsafe for drinking it contamination occurs either by nature or
activities of human beings.
Perhaps the greatest danger associated
with drinking water is contamination by human excrement (Forest 1979).
In most cases, the pollution/contamination is hardly severe and is not
particularly detrimental to health.
Thus a few substances and
microbes that are health hazard do occur in water, and can cause illness
or even death. From microbiological point of view, the pathogens most
frequently transmitted through water supply ranges from ultrasmall virus
to the microspic bacteria and relatively large cysts entemoeba
instolytica. These organism cense infectrons of intestinal trach, when
consumed censing amebic dysentery, and Gardia lamblia is a protozoa
responsible for Giadiasis. Defective plumbing for example was the cause
of out break during the world fair in Chicago 1933 (Garelick 1987) water
borne disease cause acute diarrhoe, often last 2-3 months. The most
common water borne disease can be by bacteria includes typhoid fever,
paratyphoid. Asiatic cholera and bacteria dysentery.
Other disease
that may be transmitted by water include brucellosis, shige /losis,
these disease are consuming. Untreated water (Hetolett 1921) various
countries of the world and the world Health organisation (WHO) has set
up standards for water quality against which the level of pollution can
be assessed. The world Health organization (WHO) National Agency for
food and Drug Administration control (NAFDAC), standard for potable
water include the following, that in 100ml of water coliform bacteria
should be absent, total plate count of bacteria growth should be 100
CFU/ML of water. Hence the sanitary Quality of water should not be over
looked since contaminated water can cause health hazards when consumed.
According to guideline for drinking water quality of WHO (1998)

ABSRACT - [ Total Page(s): 1 ]Samples of water from the different hostels in campus II and other source of water production namely Ajali-owa water, from bore hole 9th mile and spring water from GRA water board were water collected and analyzed using total plate count and multiple tube fermentation techniques coliform. The results shows no coliforms in production water from Ajali-owa and in GRA spring water reservaiour and no coliform in 9th mile bore hole water, 14 organism and 149 cfu/ml plate counts were obtained from tap ...
