The Dendeng River is vital for economic sustainability and viability for the community, industry and commerce around the flood plain of the river as well as raw water sources of the Kupang PDAM. However, increased domestic and industrial waste disposal along the river has caused severe pollution. One way to maintain the quality of the river is by continuously monitoring the pollutants and applying technology control as well as controlling strategy. The aim of the research mainly is to establish the water quality status of Dendeng River by water pollution Index method based on parameter physics and chemistry, i.e. pH, DO, COD, BOD, TSS, TDS, NH3-N, NO2-N, NO3-N, and PO4-P. The research was carried out based on field survey and sample examined in situ and in laboratory. The removal of water sample from Dendeng River conducted based on composite sampling as many as six point locations of Dendeng River as representative of upstream up to downstream zone. The quality status of Dendeng River is in good condition to lightly polluted with a pollution index value of 0.6 to 1.52. Value of the DO, BOD, COD, and phosphate content were higher than the allowable class 1 standard. The Water Quality Index value of Dendeng River was 86.67, which is included in the good water quality class.

“…This index was developed in 1970 by the National Health Foundation of the United States by selecting parameters utilizing the Delphi technique, where qualification of nine variables of importance that a source of the catchment for human consumption was made. It also had two toxic parameters (pesticides and toxic compounds) (Uddin et al, 2021). We applied an aggregation function based on a weighted arithmetic average to calculate the NSF-WQI index.…”

“…Despite their benefits, some water quality indices have complications in their uses or interpretations due to overshadowing problems where crucial information on water quality could be destroyed during the process of implementing the aggregation function, or problems of uncertainty where the variation in the selection of weights can affect the uncertainty of the evaluation and the decision making on the water body of interest (Uddin et al, 2021).…”

The Water Quality Index is the numerical value that qualifies in categories, the water quality of a surface stream, based on the measurements obtained for a set of physicochemical and microbiological parameters registered in a water quality monitoring network. This indicator allows knowing the physical-chemical and microbiological quality conditions of a body of water and identifies contamination problems at a certain point. In the present study, the water quality was studied in 43 stations located in the Bogota river, considering different methodologies for calculating quality indices such as NSF, Oregon, IDEAM, Prati, and diffuse logic to establish the differences, advantages, and disadvantages of each method. Similarly, a correlation analysis was carried out between the parameters, and the land uses in the basin. The results indicated that all the indices showed regular or poor water quality for more than 80% of the stations for the temporal window studied. However, the methodology used in Colombia (ICA water quality index, in Spanish) has eclipsing problems in most of the evaluation points since where the water quality qualifies as good, other indices such as the fuzzy logic show a degree of contamination by any of the parameters mainly manganese or total suspended solids.

“…Although water is one of the most abundant compounds in nature, only a small part of water resources, including surface and groundwater, can be exploited by humans [2][3][4][5]. FAO 1 forecasts show; by 2025, about 1.9 billion people worldwide will face severe water shortages, and two-thirds of the world›s population will be under water stress [6]. In recent decades, population growth, urbanization, and industrial development have polluted water resources [7,8].…”

The quality of water resources is one of the main subjects in ensuring public health. Therefore, monitoring water resources, especially surface waters, is one of the leading water operational management systems' requirements. Since the quality of surface waters is affected by natural factors and pollutants from human activity, monitoring water resources' quality leads to collecting and extracting valuable data, which needs a suitable method for interpretation and analysis. Therefore, this research assessing the annual quality of Kardeh Dam (One of the surface water sources of Mashhad) based on IRWQI SC and NSFWQI qualitative index. The results showed that the Kardeh Dam quality index in spring, summer, autumn, and winter is 55.43, 49.25, 57.61, and 60.9, respectively, indicating relatively good, average, relatively good, and relatively good quality conditions, respectively. Also, according to NSFWQI analysis, the quality index was calculated for spring, summer, autumn, and winter, respectively equal to 86.4 (good), 81.28 (good), 84.48 (good), and 96.64 (excellent). Comparisons showed that IRWQI SC was more rigorous than NSFWQI in judging the water quality of the Kardeh Dam. Comparisons indicate that the dam's water quality judgment with the IRWQI SC model is far more stringent than the NSFWQI model.
