ABSTRACT
This
Research or project is on the Assessment of the contributions of the hydrologic
cycle to the water quality profile of Otamiri River. Since the quality of the
River is polluted by the waste from different sources. This project or research
which its objective is to find out exactly the contributions of the hydrologic
cycle to the water quality of otamiri river and the health implications of
these sorts department to the users of possible solutions to the problems
observed in this cause of the study. The assessment of the contribution of
hydrologic cycle to the water quality of Otamiri, River was assessed
physically, chemically, and biologically. The method of data collection was by
primary data sources, while the results gotten from the test are the secondary
sample. Chapter three shows the sample collected from different materials of
the River (sample A, sample B and sample C). sample were tested for physical
biological & chemical parameters.
Chapter four
shows the presentation of the Result gotten from the experiment while chapter
five is the conclusion, summary and recommendations made.
CHAPTER ONE
1.1 INTRODUCTION
Since
the beginning of concern over the possible consequences of global warming, it
has been widely recognized that changes in the cycling of waters between land,
sea and air could have very significant impacts across many sectors of the
economy, society and the environment. The characteristics of many terrestrial
ecosystems, for example are heavily influenced by water availability, in the case
of aquatic ecosystems, the quantity and quality of water in rivers and aquifers
is fundamental to human, aquatic life and many activities. Most obviously
agriculture use, industry use, power generation, transportation and waste
constraint on economic development. Consequently, there have been a great many
studies into the potential effect of climatic change on hydrology (focusing of
cycling of water and water quality aspects with its proper analysis and
assessment).
The majority
of these studies have concentrated on possible changes in the water balance for
example, the quality of stream water, impacts of the changes in the gravity of
water such as the reliability of a water sources (supply) or the risk of
contaminated source. This study focuses on techniques adopted to determine the
quality of water, by carrying out chemical text, biological text and physical
text on Otammiri River to ascertain its quality and beneficial use of water.
Water And The
Hydrologic Cycle
Water begins
its never ceasing cycle as vapour in the atmosphere as well as the water in the
lakes and oceans, provides protection against extremes of both heat and cold.
Hydrologic cycle refers to the complete movement of water from the atmosphere
and below the earth surface. It includes water precipitation as rain, snow,
hail or dew, it journey over around and through obstacles above on and below
the earths surface and its eventual evaporation and return to the atmosphere.
It is the longest water purification system known to man.
Water
Water is
essential for man’s existence, it is needed in large quantities and in all
wholesomeness despite the requirements for potable supply, water is needed for
power generation, irrigation, recreation, industrial production processes and
in waste disposal. The importance of water made it possible for nature to
distribute it all over the regions of the earth. The planet earth contains
about 70% water in form of oceans, seas, rivers, lakes and ground water. Water
provided for human consumption should receive minimum possible treatment,
though the best supply is one which needs no treatment at all. Public health is
vulnerable to the danger of incidence of diseases, mainly through water borne,
water related and water washed diseases. These diseases include cholera,
typhoid and para-typhoid fever, malaria, yellow fiver, schistosomosois and
guinea worm. Consequent to the incidence of disease, water treatment processes
become a preciosity that require careful while handling. For an acceptable
quality of water supply the international standard for drinking water
established by World Health Organization (2007) states that water intended to
human consumption must be free from organisms and from concentration of
chemical substances that may be hazardous to health. Supplies of drinking water
should be pleasant to drinking as circumstance permit.
The quality
of water must be wholesome and palatable. Wholesome water must be free from
organisms, poisonous and excessive amount of mineral, turbidity taste, odour,
and must be well aerated.
1.2 BACKGROUND OF THE STUDY
This project
laid more emphasis on the assessment of the contribution of hydrologic cycle to
the water quality of Otammiri River. To understand how contamination of the
River occurs, it is necessary to understand the contributions of the hydrologic
cycle to the Rivers, the water quality along its profile from the confluence of
Otammiri and Nworie River. Water bodies can be fully characterized by the three
major components; hydrology, physic-chemistry and biology. Therefore this
project describes a complete assessment of water quality based on appropriate
monitoring of these components.
1.3 OBJECTIVE OF THE STUDY
The aim of
this project is to provide understanding of;
i. The
assessment of the contributions of hydrologic cycle to Otammiri River from the
broadest perspective.
ii. Water
quality potentials of Otammiri River
iii. Physical,
chemical and biological characteristics of water
iv. Water
quality control and management.
v. Water
quality in the environment, sources of contamination, effects of common
impurities in water and self purification of water.
1.4 SCOPE OF THE STUDY
The scope of
this project is the proper assessment of the contribution of hydrologic cycle
to Otammiri River which include;
a. Assessment
of existing surface water (Otammiri River during rainy season as a case study)
i. Effects of
common impurities in water
ii. Water
quality and characteristics of water
iii Beneficial
use of water
iv. Study
methodology, decision on quality parameters for analysis.
v. Data
presentation, calculation and discussion.
1.5 RESEARCH HYPOTHESIS
While there
is a considerable amount of water quality data collected for the experiment,
the timing and frequency of samples does not provide a definite information on
the degree which water quality is based. The following was needed to determine
the water quality conditions.
i. Three
different samples would be collected from difernt reaches of Otammiri River
ii. The samples
should be taken undisturbed and moved to the laboratory immediately for proper
analysis.
iii. The
presence of the following should be determined; copper, zinc, magnesium, iron,
sulphate, phosphate, nitrite, chloride and sulphite.
iv. Also, the
following should be determined; pH, conductivity, total dissolved solids, total
suspended solids, alkalinity, total hardness, turbidity, total coliform, etc.
1.6 SIGNIFICANCE OF THE STUDY
i. This
project provides an account on how to make hydrologic cycle and water quality
fit for human use.
ii. The various
treatment method of contaminated water
iii. It provides
information on how the River is being contaminated along the reaches of the
river.
1.7
LIMITATION OF THE STUDY
In the course
of carrying out this project, some difficulties were encountered which
includes;
i. Unavailability of research material like test books
ii. Unsteady
power supply that delayed the laboratories experiment
iii. Difficulties encountered when analyzing different water sample
iv. Non
availability of equipment needed for water quality analysis.
