“…On this basis, all the water samples were almost neutral to slightly alkaline. These values aligned with the findings of other researchers (Al-Jiburi and Al-Basrawi 2015; Barakat et al 2018) who reported that the pH of water sources in the area are characterized by a shift toward the alkaline side of neutrality; this might be due to the geological composition of the region, which consists largely of calcium carbonate (CaCO 3 ) (Al-Jiburi and Al-Basrawi 2015). The pH values in all the study sites were within an acceptable range (6.5-8.5) for both dry and wet seasons.…”

“…The mean turbidity readings of the samples at all sampling sites and in both seasons were in the range of 0.02 to 0.06 Nephelometric Turbidity Units (NTU). Turbidity levels are very low compared to results of other studies (Al-Jiburi and Al-Basrawi 2015; Barakat et al 2018;Shigut et al 2017), and the results were far below the permissible level (5NTU) suggested by Iraqi and international standards for drinking water. According to (Barakat et al 2018), "the higher levels of turbidity caused by suspended solid particles are due to fast transport pathway connecting potentially contaminated surface water with the aquifer."…”

“…The relative abundance of major dissolved chemical constituents in water is dependent upon weathering process, type of geological rock (Singh and Hasnain 1999), and inputs from anthropogenic activities. The physicochemical analysis is used for detecting the levels of these dissolved constituents in water (Barakat et al 2018). Accordingly, in the current study, the collected samples from spring water in different villages in the Barwari Bala region were analyzed for 12 physicochemical parameters.…”

“…Thus, information on water resources and their suitability for use is mandatory for spatial planning and sustainable development. This is of particular importance in arid and semiarid areas, where water resources are limited and the long-term average precipitation is decreasing (Barakat et al 2018;Mishra and Singh 2010;Tallaksen and Van Lanen 2004).…”

Periodic quality assessment of drinking water sources is necessary to guarantee the quality and security of water supply to people. Accordingly, this study assessed the drinking water quality of spring water of some villages located in Barwari Bala region of Duhok Governorate, Kurdistan region, Iraq, using the water quality index (WQI). To realize this objective, 120 spring water samples were collected from ten villages during the dry and wet seasons in 2018 and were analyzed for major physicochemical characteristics, including: calcium (Ca 2+), magnesium (Mg 2+), sodium (Na +), potassium (K +), chloride (Cl −), sulfate (SO 4 2−), nitrate (NO 3 −), pH, total dissolved solids (TDS), turbidity, total hardness (TH) and total alkalinity (TA). The results for pH, turbidity, sodium, potassium, chloride, sulfate and nitrate showed that the water samples at all the sampled springs were suitable for drinking and within permissible limits based on given standards. However, TDS, TA, calcium and magnesium exceeded the permissible limits at some sites. It was also observed that, except for SO 4 2− , at almost all the sites, the majority of parameters were significantly greater during the wet season compared to the dry season. With reference to all the parameters, the WQI values ranged from 10.76 to 18.13 during the dry season and from 17.10 to 20.45 during the wet season, indicating that all water samples are classified as having "excellent" water quality for drinking purposes. The calculation of WQI based on specific parameters, where values were close to or exceeded the maximum acceptable limits, showed that the water quality status of all water samples was "good" quality, except for sites S6 and S8, which were classified as "poor" quality and are not considered suitable for drinking purposes without treatment. Water from almost all the sampled spring sites can be considered as suitable for drinking purposes, although some parameters exceed permissible limits. Simple filtration treatment of the sampled spring water before use is desirable for ensuring good quality and security of the water supply to people of these areas.

“…Monitoring and controlling surface waters are necessary and vital to assure the availability of high-quality water for its many uses (Bollinger et al 1999;Sánchez et al 2007). One of simple methods that can recount the qualitative conditions of water is the use of water quality indexes (Hoseinzadeh et al 2015;Barakat et al 2018). The National Sanitation Foundation Water Quality Index (NSFWQI) is one of the popular indexes classifying surface water quality that is determined based on temperature, phosphate, nitrate, dissolved oxygen, total solids, biological oxygen demand, pH, and fecal coliform bacteria.…”

Water quality evaluation using water quality index and multivariate methods, Beheshtabad River, Iran

Rivers are critical to agriculture, industry, and the needs of humans and wildlife. This study evaluates the water quality of the Beheshtabad River in Iran's Chaharmahal and Bakhtiari Province, using water quality index and multivariate statistical methods. Nitrate, temperature, phosphate, turbidity, dissolved oxygen, biological oxygen demand, electrical conductivity, total solids, and pH were measured at five selected stations along the river over 6 months using standard methods. Water quality index results demonstrated that water quality varied in the selected stations between average and good and that pollution in this section of the Beheshtabad River increases from upstream to downstream. Clustering and principal component analysis were also utilized. Multivariate statistical methods were used to analyze water conditions for efficient management of surface water quality. Agricultural fertilizers, upstream wastewater discharge, and fish farms constitute the main elements that decrease the water quality of the Beheshtabad River. To preserve this water resource against pollution, the implementation of stringent rules and guidelines are needed to enhance health and preserve water resources for future generations.
