| Summary: | Water quality is very crucial in ensuring the sustainability of human activities and
survival. In Malaysia, river water quality is constantly monitored and evaluated by the
water quality index (WQI) established by Department of Environment (DOE). Water
quality index (WQI) is a quantitative indicator that can easily determine the pollution
condition of river water. It utilises six critical water quality parameters to portray the river
water quality. Weightage is assigned to each parameter to signify the influence of the
parameter. The WQI is then quantified to obtain a numerical value, which represents the
pollution level of the river water. The pollution status of the river water can also be
categorised in various classes, depending on the intended use of the water body. Besides,
the water quality index is also compared with other standards used in several countries.
The advantages and disadvantages of each standards are determined. A new graphical
method, “Eco-Heart Indicator” is proposed to serve as an alternative tool to portray the
health of the river water. In this research, Selangor River is selected as the basis of study.
The data obtained from Department of Environment (DOE) are used to plot Eco-Heart
Indicator and compared with the Water Quality Index (WQI). The graphical
representation of the water quality is hoped to become an easier communication tool to
the public in addressing the awareness of river water status. |
