“…The study area was selected based on the factor of the population of Rinching Town area was involved in water supply disruption that had to be implemented on the districts in Selangor. The main domestic water supply sources for Rinching Town are the Semenyih River, Lalang River, and Rinching River after the Semenyih Dam treatment [29]. Based on observations, most residential areas in Rinching Town are comprised of two-story and single-story terrace housing areas.…”

Management of water supply in urban areas is a challenge that must be faced by water supply companies to ensure the continuity of domestic water supply to the residents in the area. Hence, this study aims to identify local people’s behavior and daily activities that led to domestic water wastage. Furthermore, the relationship between the demographic factors of the population trends in reducing water use through water savings in their daily activities or installing a home-saving water system is also undertaken. The data were analyzed and interpreted using IBM SPSS software such as descriptive analysis, covering frequencies, mean and standard deviation, correlation with bivariate correlation, cross-tabulation, and multivariate analysis (MANOVA). Availability and demand in water management will only be managed if water resources and water supply engineers address all the balance sides. It will ensure a more comprehensive and interconnected water sector, ensuring the security and sustainability of water.

“…Accordingly, the maximum concentration of Cr (12.2 × 10 −4 mg/L) in the Langat River indicated pollution in the mid-stream of the river basin from metal finishing industries such as electroplating, etching, and preparation of metal components for various industries [6,80]. Similarly, corrosion inhibitors, pigments from industrial effluents, and lithogenic sources contributed to high concentrations of Cr in Langat River [10,81].…”

“…Therefore, these metals have been listed as the toxic trace metals by the United States Environmental Protection Agency (USEPA) if ingested via drinking water. The natural weathering of mineral rocks is considered as the main source of Cd and Cr in the Langat River, Malaysia [9,10]. Low concentration of dissolved Cd (1 × 10 −3 mg/L) was reported by Mamun et al [11] in the Langat River; however, Sarmani [12] and Yusuf [13] observed very high concentration of Cd in Langat River (35.56 × 10 −3 mg/L and 24 × 10 −3 mg/L, respectively).…”

Although toxic Cd (cadmium) and Cr (chromium) in the aquatic environment are mainly from natural sources, human activities have increased their concentrations. Several studies have reported higher concentrations of Cd and Cr in the aquatic environment of Malaysia; however, the association between metal ingestion via drinking water and human health risk has not been established. This study collected water samples from four stages of the drinking water supply chain at Langat River Basin, Malaysia in 2015 to analyze the samples by inductivity coupled plasma mass spectrometry. Mean concentrations of Cd and Cr and the time-series river data (2004–2014) of these metals were significantly within the safe limit of drinking water quality standard proposed by the Ministry of Health Malaysia and the World Health Organization. Hazard quotient (HQ) and lifetime cancer risk (LCR) values of Cd and Cr in 2015 and 2020 also indicate no significant human health risk of its ingestion via drinking water. Additionally, management of pollution sources in the Langat Basin from 2004 to 2015 decreased Cr concentration in 2020 on the basis of autoregression moving average. Although Cd and Cr concentrations were found to be within the safe limits at Langat Basin, high concentrations of these metals have been found in household tap water, especially due to the contamination in the water distribution pipeline. Therefore, a two-layer water filtration system should be introduced in the basin to achieve the United Nations Sustainable Development Goals (SDGs) 2030 agenda of a better and more sustainable future for all, especially via SDG 6 of supplying safe drinking water at the household level.

Abstract:The information-analytical system (IAS) "Monitoring of aquatic ecosystems" was developed for the analysis of ecological lakes condition in Kazakhstan. It consists of a database on hydrochemical and hydrobiological characteristics for lakes Burabai and Ulken Shabakty in Shchuchinsk-Borovoye resort area of the Republic of Kazakhstan, as well as a set of statistical data processing methods. Qualitative analysis of data was made on the lakes. Data on biogenic substances for the years 2007-2013 were analyzed based on statistics. Dynamic characteristics and seasonal features of changes were identified in the concentrations of biogens. There is an absence of significant relationships between the concentrations of various biogenic substances in lakes and between lakes. Nitrogen substances were compared. The phosphorus compounds have a large stability that can contribute to a more stable life of phytoplankton species which are related to phosphorus.
