The influence of physico-chemical parameters to determine water quality: a review / Azhar Jaffar ...[et al.]

Water plays a significant role in domestic,
agricultural, fisheries, and many other industries. Unfortunately,
with the changes that have taken place in the environment today
has contributed a profound impact on the water quality, which
furthermore lead to the rise of the new water-based diseases to the
human population. To meet the needs of all, the source of the
supplied water must be clean and unpolluted. To ensure the
quality of the water, the Physico-chemical parameters in the water
must be regularly reviewed and tested. The objective of this paper
is to review several Physico-chemical factors that can be used to
determine the quality of the water and detect the appearance of
the contamination agent in that particular water source. The
findings and views from a few researchers on these parameters
are discussed in this work. From this review, it can be concluded
that changes in Physico-chemical parameters such as
temperature, pH, salinity, Total Dissolve Solid (TDS), turbidity,
Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and
Chemical Oxygen Demand (COD) alone cannot be used to
determine the quality of the water. These parameters must be
stood as the collaborative parameters to have a significant effect
on the determination of the water quality.
