| Summary: | Environmental engineering studies include a special area of study,
which focuses about water and wastewater treatment and water quality control.
Another important thing related to environmental engineering is the study about
the Water Quality Index (WQI). WQI is the best approach for simulating the
physical, chemicals, and biological changes in the aquatic systems. The aim of
this study is to determine the WQI for UNIMAS lake and to classify the water
based on the Department of Environmental standards and the Interim National
Water Quality standards for Malaysia. This study focuses on the physical and
chemical parameters such as Dissolved Oxygen (DO), Biochemical Oxygen
Demand (BOD), Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH3-
N), Total Suspended Solids (TSS) and Hydrogen Ion Concentration (pH). Six
experimental works involved in physical and chemical parameter was carried out
to finalize all the parameter value before determining the WQI for UNIMAS lake.
From this study, the value of WQI for UNIMAS lake is 91.44 and the lake can be
classified as “Clean”. The lake also can be classified as “Class II” which is
suitable for water supply with a conventional treatment required, suitable for
sensitive aquatic species and also suitable for recreational use with body contact. |
