“…The influence of river location on high TDS levels is caused by ionic elements Na+ and Cl -, so it is equated with the levels of these two ionic elements in seawater, where seawater has high TDS levels (Orji et al, 2013). Turbidity can be converted with TDS and TSS levels.…”

Raw water quality for drinking water is a strategic issue requiring attention and environmental dynamics. River quality changes are crucial for sustainability and monitoring suitability. Kali Pelayaran, a tributary of the Brantas River, is a key source for drinking water in Sidoarjo Regency. The aim of the research is to analyze the water quality status of the Kali Pelayaran river as a basis for mitigating the sustainability of raw drinking water in Sidoarjo Regency. The length of the segment analyzed starts from the upstream branch of the Brantas River which enters the Pelayaran River to the intake of the Tawangsari WTP, a distance of 21 kilometers. The research method that will be implemented is: analyzing the existing condition of the water quality of the Kali Pelayaran river which is divided into 8 segments by measuring the quality status of the river using the Pollutant Index (IP). Next, use the K-means method to create clustering based on the measured level of quality status. The water and sediment quality parameters analyzed were pH, temperature, DO (Dissolved oxygen), BOD (Biological oxygen demand), COD (Chemical oxygen demand), TDS (Total dissolved solids), and TSS (Total suspended solid). Research conclusions was formulated in an integrated manner regarding the description of current conditions and predictions for the future, presented in the form of tables, graphs, and maps.

“…The first three simulations were carried on as the initial location of particle is at grid (1,14) with increasing particle diameter from 70 μm, to 515 μm and 2855 μm. The fourth simulation is performed to observed how does the increase of particle density affect the transportation, while the fifth and sixth simulations were carried on by changing the initial location of particle which were (2.5, 5) and (25,14) respectively. Each of the particle motion are demonstrated in the graphs as follows: From the results obtained, it is shown that with increment of particle diameter, the particle transportation in term of displacement will increase.…”

Kinta River is one of the major rivers spanning 17.1km from Tanjung Rambutan to Ipoh, Perak. Kinta River is important as both water source for local population as well as various economic activities. It is unavoidable that human activities cause siltation and sedimentation in the river. Suspended sediment is one of the main contributors to the turbidity problem in the river and it brings huge impact to the environment. This study aims to predict the transportation of sediment through displacement by application of LABSWE TM . The model developed provides information about the sediment location and mitigation solutions could be proposed to tackle the turbidity issue of the river. In this study, the LABSWE™-Lagrangian Model is used to predict the particles transportation in water. It is shown the settling velocity generated by gravitational force could not be neglected. When the particle density increase, the corresponding sediment transportation increases. However, the density factors do not have significant effect to the particles as the particles are relatively small in grain size.

“…The COD is used to measure how bad the pollution is. COD is the amount of oxygen required to oxidise the (Ku Orji et al, 2013;Mohd Harun, 2012). The COD values for these five former mining lakes in November 2015 ranged from 1.00 to 11.67 mg/L and from 9.00 to 14.33 mg/L in January 2016 (Figure 4).…”

“…Among the sources of pollution resulting from the former tin mining lakes are heavy metals, such as mercury (Hg), arsenic (As), cadmium (Cd), zinc (Zn), copper (Cu) and lead (Pb) [Kah et al, 2016;Ku Orji et al, 2013;Ashraf et al, 2012;Zulhadi, 2006]. In this study, the analysis of heavy metals were limited to Pb, Cu, As and Zn in the water around the former mining lake area.…”

A study of the water quality of the former tin mining lakes in Ipoh City was carried out to determine the Water Quality Index (WQI) and classification based on the Malaysia National Water Quality Standards, in order to determine its suitability to be developed as a water recreation area. Five former mining lakes were chosen: Gunung Lang, Taman Indah, Kg. Temiang, Lahat and Kg. Engku Husin. The parameters measured were pH, dissolved oxygen, suspended solids, biochemical oxygen demand, chemical oxygen demand and ammonical nitrogen (NH3N), while the heavy metals measured were lead (Pb), copper (Cu), zinc (Zn) and arsenic (As). The analytical study shows that four former mining lakes in this research are suitable to be developed for water recreation purposes as they are classified under class II with a WQI greater than 81, which holds a clean status. Only one lake, Kg. Engku Husin, is categorised as class III, which requires an intensive treatment before it can be used for recreational purposes. Meanwhile, heavy metals such as Zn, As and Cu were at the standard level except for Pb, which exceeded the set guidelines. The local authorities and project developers should take appropriate measures to ensure that this former mining lake is well maintained and managed so that it is preserved and suitable to be developed as a recreational area.
