“…Based on Kelly's ratio, all samples examined in this source are appropriate for use, according to the data in Tables 2 and 4. The results obtained for the ratio in this study are in agreement with the majority of the groundwater samples determined in Southern India (Anbazhagan and Jothibasum 2014).…”

The quality of well-dug water for drinking and irrigation purposes must be measured as part of a sustainable groundwater analysis. The study aimed to assess water quality and to evaluate their usefulness for drinking and irrigation, using the Drinking Water Quality Index (DWQI) and Irrigation Water Quality Index (IWQI). To achieve this, standard methods were used for the determination of physicochemical parameters of the water samples, while using models (ESP, SSP, SAR, MAR, KR, TDS, and EC) to ascertain their suitability for drinking and irrigation. According to the findings, the determined Physico-chemical parameters were compared to standard limits and found desirable because they were within the guidelines. Low pH (6.4-7), total dissolved solids (106–130 mg/L), total hardness (42–56 mg/L), calcium (3.5–8.3 mg/L), magnesium (1.13.6 mg/L), nitrate (4.6–16 mg/L), chloride (1.8–3.1), and sulphate (14–15. mg/L) in the well samples were found to be the key cause of the low DWQI and IWQI value at these sites. The results also depicted that all the water samples are of exceptional quality (excellent).

Quaternary groundwater aquifer suitability for drinking in Akhmim, Upper Egypt: an assessment using water quality index and GIS techniques

2022

The Quaternary aquifer has a special significance in Akhmim district, Upper Egypt, especially during the dry seasons, when surface water resources are insufficient and limited. In Akhmim district, the population mainly depends on groundwater for drinking, especially in spontaneous residential areas and inside agricultural lands. Therefore, assessing the groundwater quality is necessary to reduce diseases resulting from using polluted water in drinking. The Weighted Arithmetic Water Quality Index (WAWQI) was used for evaluating the groundwater quality, and it was classified according to the Egyptian and WHO standards and based on fifteen measured physicochemical parameters (TDS, Na, Cl, Ca, pH, Mg, NO3, SO4, TH, Cr, Cu, Fe, Pb, Mn, and Zn). To investigate the spatial distribution of WAWQI in Akhmim district, the spatial analyst tools (IDW method) were used. The WAWQI results showed a great diversity in groundwater viability for drinking due to the exposure of groundwater to many sources of degradation, identified through field verification and previous work about the study area. The groundwater of the Quaternary aquifer was divided into excellent, good, poor, very poor, and unsuitable. In addition, about 50% of Akhmim district wells are inappropriate for drinking with classes ranging from unsuitable to poor. To use groundwater for drinking, the sources of degradation to which the groundwater is exposed must first be reduced, and the water should be treated before drinking.

Groundwater quality of the arid and semi-arid regions needs great attention because it is the main water exporter for household and irrigation purposes. In this study, the traditional method and the water quality index were applied to evaluate the suitability of groundwater quality for drinking and irrigation purposes in southwestern part of Libya. To achieve this, twenty groundwater samples were collected from different places representing the area understudy and the necessary physic-chemical analyzes were carried out to examine the suitability of groundwater for drinking purposes. Eleven parameters (pH, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, sodium, potassium, chloride, bicarbonate and sulphate) have been applied for calculating the WQI for drinking testes. The obtained values for water quality parameters were compared with World Health Organization (WHO) guideline values (traditional method). Also, seven parameters were selected for irrigation testes for calculating the WQI such as: EC, SSP, SAR, MAR, PI, KR and PS were used in traditional method. The results revealed that the groundwaters of most samples were fit for drinking purposes according to WHO (traditional method). However, the calculated DWQI for drinking propose showed that 35% of water samples are considered of excellent category, 20% good category, 15% poor category and 20% very poor category. On the other hand, two samples (only 10%) are of unsuitable categories. For irrigation purposes, most of studied samples were suitable for irrigation purposes (traditional method). The computed IWQI showed that 15% of water samples were in excellent category and 85% were in good category. The graphical interpretation of water quality was made according to Gibbs plots, Piper diagram, Chadha's scheme, USSL diagrams, Wilcox diagram and Doneen diagram. KEYWORDS Drinking water quality index (DWQI), Irrigation water quality index (IWQI), water quality parameters The main objective of this study is to using the traditional method and the water quality index (WQI) to assess the suitability of groundwater quality in the study area to drinking and irrigation. 2. LOCATION OF STUDY AREA The area under investigation is located on the northwestern area of Libya (Wadi Al-Hayaa). It lies between latitudes 26° 30′ and 28° 30′ N and longitudes 12° 15′ and 14° 30′ E (Figure 1). The area is characterized by the rural environment and the main activity of the people is agriculture. Water in this area is generally obtained from drilling wells that are used for different purposes.
