CHAPTER ONE
1.0INTRODUCTION
1.1Background of the Study
Water is
indispensable to life and it is given priority in sitting of
settlements, industries and farms. Harigan and Macance (2001) reported
that water sourced from river, streams and lakes are subjected to
calcium, magnesium, sodium and potassium. Also silica, free carbonic
acid, oxygen, carbonic acid and other trace element Cifluent et al
(2002) pointed out that one of the most deadly contamination of water is
faecal contamination, water bodies got contaminated with faeces of
human during activities such as defaecation, these kind of
contaminations common in rural areas where they defecate wash swim in
water bodies. Moreover, the bursting of soakway pit into water bodies
are also common both in rural and urban areas. Industries discharge into
rivers, streams etc also causes the presence of knoxocarbonates and
silicates these, apart form contamination induces permanent hardness in
water.
A review of 28 studies carried out by he World Bank gives the
evidences that incidence of water borne diseases are related to the
quality of water and sanitation available to users. Ikeh et al (2002)
highlights that a contaminated water organisms especially of the
enterobacteriaceae group e.gEscherichia coli, Enterobacter aerogenes,
Klebseilla pneumoniae and non coliforms; Shigella dysenteriae,
Salmonella typhi, Versinia enterolitica are high contaiminated in the
water. Cabelli, (2002) explains that these organisms when ingested in
the body produces toxins that causes food borne diseases such as
cholera, salmonellosis, gastrointestinal disorder, Hepetitis Piolio,
amoebic dysentery, crystosporidiosi, Toxoplasmosis etc.
Ksiteman
(1990) explains that in order to prevent the outbreak of water there are
needs to preserve and treat water supplied to towns and cities. The
methods of treatment of water are thus, boding of water at 1000C, the
prevents the growth of pathogenic organisms, boiling of water does not
get rid of spore forming organism, water and killing of pathogenic
organisms.
Organic waste is produced wherever there is human
habitation. The main forms of organic waste are household food waste,
agricultural waste, human and animal waste. In industrialized countries
the amount of organic waste produced is increasing dramatically each
year. Although many gardening enthusiasts ‘compost’ some of the their
kitchen and garden waste, much of the household food waste goes into
land fill sites and is often the most hazardous waste. The organic waste
component of lanfill is broken down by micro-organisms to form a liquid
leachate’ which contains bacteria, rotting mater and may be chemical
contaminants form the landfill. This leachate can present a serious
hazard if it reaches a water course or enters the water table. Digesting
organic matter in land fill if it reaches a water course or enters the
water table. Digesting organic matter in landfills also generates
methane, which is a harmful green house gas, in large quantity. Human
organic waste is usually pumped to a treatment plant where it is
treated, and then the effluent enters a water course, or it is deposited
directly into the sea, little effort is made to reclaim the valuable
nutrient or energy content of this waste.
In developing countries,
there is a different approach to dealing with organic waste. Infact, the
word ‘waste’ material and reclaim it for further use. Where large
quantities of waste are created, usually in the major cities, there are
inadequate collected facilities for dealing with it, and much of this
waste is either left to rot in the stress, or is collected and dumped on
open land near the city limits. There are few environmental controls in
these countries to prevent such practices.
1.2Aims of the Study
1) To determine the effect of organic waste on water
2) To determine the effect of organic waste on physical, chemical and biological properties of water in Enugu State.

The water sample were analyzed for various chemical and microbial parameter. The bacteriology techniques. The micro organisms isolated and characterized include eight (8) bacterial while fungal (4) genera. The bacterial isolated were klebsilla, pseudomonas, Escherichia, staphylococcus, proteus and bacillus and the fungal isolated were Asper ... Continue reading---
