“…This condition is the same as the research done in Sistan-Baluchestan, Iran [11], Central Mexico [17], and Kosovo [18]. [11] The TDS and groundwater electric conductivity increase as the groundwater flow to the north as the river flows. [17] Groundwater in the plains area has a higher TDS and groundwater electric conductivity value than groundwater in the valley.…”

“…In this research, we analyze the pattern and direction of groundwater flow and distribution of physical-chemical properties of groundwater using Geographic Information System (GIS). This method has been applied in many similar research, such as on Pekanbaru Regency, Indonesia in 2015 [7], Harare, Zimbabwe in 2019 [8], Kupang Regency, Indonesia in 2020 [9], Coimbatore, India in 2021 [10], Sistan and Baluchestan Province, Iran in 2021 [11]. This research aims to analyze the pattern and direction of groundwater flow and the distribution of physical-chemical properties of groundwater in the Randublatung basin.…”

The people in the Randublatung basin (Grobogan, Blora, and Bojonegoro Regencies) using groundwater for daily needs and agriculture activity. As the initial step of basin-based groundwater management, it is necessary to understand the groundwater potential in this area: pattern and direction of groundwater flow and groundwater physical-chemical properties (pH, temperature, total dissolved solids, and electrical conductivity). This research aims to analyze the pattern and directions of groundwater flow, the physical-chemical properties, and the correlation between the two. This research method is field measurement of 45 different spots of dug wells in the Randublatung basin. Our results indicate that the pattern and direction of groundwater flow in the Randublatung basin are heading to Bengawan Solo River and then following the river’s flow. The groundwater physical-chemical properties measured: pH value is 6.8 on average, the temperature is 28.9 °C on average, TDS concentration is 409 mg/L average, and electrical conductivity rate is 843 μS/cm average. There is no significant correlation between groundwater flow with pH value and groundwater temperature. However, groundwater TDS concentration and electrical conductivity rate in the Randublatung basin increase as groundwater flows to the Bengawan Solo River, which is affected by the minerals of aquifer rocks (alluvial deposits).

“…The concentrations of calcium and magnesium, which are multivalent (+2) cations, form hardness of water, changed between 195 and 1341 mg CaCO3/L. Rock types such as calcite and dolomite contain calcium and magnesium [30]. The low amount of calcium and magnesium in drinking water can negatively affect bone development in children, while high concentrations can cause kidney stone formation, and arthritis problems [31,32].…”

This study investigates the spatial and temporal changes in groundwater levels and quality in the Palas Basin, a relatively-pristine semi-arid agricultural basin in T . Although groundwater is solely used as irrigation and drinking potable water resource throughout the basin, measurements regarding the dynamics and quality of groundwater were quite rare. The analyses were based on data collected from 12 water quality monitoring wells and 15 groundwater level monitoring wells during June 2019-May 2020. Water samples were analyzed for pH, electrical conductivity, temperature, nitrate, nitrite, ammonium, total nitrogen, total hardness, alkalinity, chloride,sulfate, phosphate, total organic carbon, calcium, magnesium, sodium, potassium, and arsenic. Data analyses included hydrogeochemical analysis and multivariate statistical analysis such as principal component analysis and cluster analyses. Results showed that water quality in the basin is mostly controlled by natural factors, however, anthropogenic impacts from agriculture activities were apparent in some regions. The basin shows significant changes in water levels throughout the year due to irrigation activities. The groundwater quality was classified as either Ca-Mg-HCO3and Ca-Mg-SO4 type. In the majority of the basin, water quality was suitable for irrigation and drinking water uses, however, a few sampling sites had very high electrical conductivity, sulfate, nitrate, and arsenic levels. The high levels of nitrates were detected in areas, where agriculture is intense, indicating that agricultural activities might be affecting water quality. High sulfate, electrical conductivity, and arsenic levels could be related to the hydrogeological setting of the basin. This study showed that agricultural activities and natural factors were effective on the hydrogeochemical characteristics of the Palas Basin.

“…In this study, the monthly water balance is investigated using the WetSpass-M distribution model. Numerous studies have also been conducted on the quality of groundwater resources (Ebrahimi et al, 2016;Yehia et al, 2017, Khalid, 2019Ratolojanahary et al, 2019;Loh et al, 2020;Sargazi et al, 2021;Masoud and Ali, 2020) or the relationship between drought and water quality (Hrdinka et al, 2012;Mosley, 2015;Li et al, 2018;Kim et al, 2019;Mishra et al, 2021). But the present study intends to investigate the quality of groundwater from several aspects and examine its relationship with water balance components.…”

One of the problems of water resources in Iran is excessive drop in groundwater level, in which Chaharmahal va Bakhtiari province, located in this country, is no exception․ In this study, the trend of spatial and temporal changes in groundwater quality and water balance and the relationship between them in this province were investigated. The WetSpass-M distribution model was used due to the capability of distribution models in simulating watershed hydrological processes. The results showed good accuracy of the model in simulating runoff and basal flow of the study basin. The trend of water quality changes was investigated by calculating the IRWQI index and preparing its zoning maps. For this purpose, 132 samples of well water in different areas of the study were prepared in 2007 to 2017. Spatial distribution maps showed that the groundwater quality in the north and northeast of the region was lower than in other parts. Also, groundwater quality had declined over time. In rangeland, groundwater quality was better and nitrate level was lower than in agriculture and buildup land uses. Also, the relationship between nitrate and drought with water quality was seen due to the similar color pattern in their zoning maps in the region. The correlation between groundwater quality parameters and water balance components also showed a weak correlation on an annual scale and a strong correlation between some parameters in some wells on a monthly scale.
