The
Problem and Its Setting
Introduction
Water is an essential part
of life. It is used by plants, animals and humans. People use it for many purposes.
It can be used for taking a bath, washing clothes, cooking and especially for
drinking. People are advised to drink clean and fresh water only. Even if the
water is fresh, it will still contain some salt content. Water with high coliform
content or high turbidity is not safe for drinking nor for bathing.
There
are different parameters used as basis for clean water or safe water. The
parameters which will be used in this water analysis are coliform, turbidity, pH,
temperature, dissolved oxygen, conductivity and salinity.
Statement of
the Problem
This water analysis, known
as “Identifying the Differences between Salt Water and Fresh Water in terms of
Coliform, Turbidity, Temperature, pH, Dissolved Oxygen, Conductivity and
Salinity” was conducted with the aim of determining the differences between
salt water and fresh water among seven given parameters which could affect its
safety towards the use of humans and other living organisms.
Specifically,
it attempted to answer the following problem:
“What are the significant differences between salt
water and fresh water in terms of:
a.
Coliform,
b.
Turbidity,
c.
Temperature,
d.
pH,
e.
Dissolved Oxygen,
f.
Conductivity, and
g.
Salinity?
Hypothesis
With
the abovementioned problem, the researchers hypothesized that:
“There are no significant differences between salt
water and fresh water in terms of: coliform, turbidity, temperature, pH, dissolved
oxygen, conductivity and salinity.”
Scope and
Delimitations
This water analysis looked
into the differences between salt water and fresh water in terms of coliform,
turbidity, pH, temperature, dissolved oxygen, conductivity and salinity to know
the safety of the water in human usage. This water analysis only made use of
seven (7) parameters which were coliform, turbidity, pH, temperature, dissolved
oxygen, conductivity and salinity. Conductivity, pH and dissolved oxygen were
only measured through a water analysis device and the device sensor and no
other method as used. Also, only the surface temperature of the water was
measured. The amount of coliform was only measured by the Department of Science
and Technology (DOST) in Legazpi City.
The
study did not attempt to find out the different parameters’ effect on other
organisms. Also, the study did not consider different amounts of the samples.
Significance
of the Study
The output of this water
analysis would somehow benefit the following persons, entities and environment:
People. The results of this research
will help people know which type of fresh water could be safe for drinking. It can
also determine which water is good for cooking, cleaning and bathing.
Environment. The results of the
analysis will enable the people to determine what is clean water. People could
take appropriate measures when they detect water to be unsafe for use. Also, no part of the environment was harmed
nor broken while conducting this analysis.
Fishermen. The results of the research
will allow them to know which type of water has better catch. It would also
allow them to know which type of water has cleaner water, which can also have
safer fish to eat.
Department of Health (DOH). This agency
of the government can furthermore study the results of the water analysis so
that they could monitor the safety of each area of water. They could allow the
safer consumption of fresh water by knowing which water is cleaner.
Future Science Researchers. This
analysis would motivate and encourage future researchers to venture into more
areas that could be tested of different parameters, aimed at determining safe
water.
