“…This phenomenon is mainly attributed to children's bodies being more sensitive, lower weight and less immune than adults, so they are more susceptible to health risks by ingesting water containing high concentrations of fluoride and iodine. This finding is consistent with many previous studies in other regions such as China, India, Iran and so on [64][65][66]. Long-term drinking of high fluoride groundwater will endanger human health, so it is suggested that before groundwater is used as drinking water, adsorption method and chemical sedimentation method can be applied to reduce the concentration of fluorine and protect the safety of the drinking water environment.…”

Groundwater is an irreplaceable resource for irrigation and drinking in the North China Plain, and the quality of groundwater is of great importance to human health and social development. In this study, using the information from 59 groups of groundwater samples, groundwater quality conditions for irrigation and drinking purposes in an agricultural region of the North China Plain were analyzed. The groundwater belongs to a Quaternary loose rock pore water aquifer. The depths of shallow groundwater wells are 20–150 m below the surface, while the depths of deep groundwater wells are 150–650 m. The sodium adsorption ratio (SAR), sodium percentage (%Na), residual sodium carbonate (RSC), magnesium hazard (MH), permotic index (PI) and electrical conductivity (EC) were selected as indexes to evaluate the shallow groundwater suitability for irrigation. What’s more, the deep groundwater suitability for drinking was assessed and the human health risk of excessive chemicals in groundwater was studied. Results revealed that SAR, Na% and RSC indexes indicated the applicability of shallow groundwater for agricultural irrigation in the study area. We found 57.1% of the shallow groundwater samples were located in high salinity with a low sodium hazard zone. The concentrations of fluorine (F−) in 79.0% of the deep groundwater samples and iodine (I−) in 21.1% of the deep groundwater samples exceeded the permissible limits, respectively. The total hazard quotient (HQ) values of fluorine in over half of the deep groundwater samples exceeded the safety limits, and the health risk degree was ranked from high to low as children, adult females and adult males. In addition to natural factors, the soil layer compression caused by groundwater over-exploitation increased the fluorine concentration in groundwater. Effective measures are needed to reduce the fluorine content of the groundwater of the study area.

“…They believe that the chemical characteristics of groundwater are determined by the sedimentary environment and are affected by interactions between natural and human factors (Hua et al 2020;Liu et al 2020). groundwater undergoes various physical and chemical interactions with surrounding media during the process of formation and transportation, including dissolution/precipitation, acid-base balance, adsorption/desorption, and oxidation-reduction (Gao et al 2021). The spring groups in Jinan experienced four historical evolution periods: perennial gushing period, gushing transition period, attenuation period and artificial regulation periods (Guan et al 2019).…”

Karst water is one of the main drinking water sources in North China. The single factor method and projection pursuit algorithm (PPA) are employed to assess the karst water quality of the Baotu spring area in Jinan. The water quality distribution pattern, its causes, and the main groundwater pollution sources are analyzed. The water quality evaluation results of the PPA model are more reliable than those of the single factor method because the PPA model comprehensively considers the weight and correlation of various factors. The water quality of the study area is generally excellent, but the NO3− index content is high. In recent years, the water quality grades have been mainly class II ∼ class IV. The driving factors of water quality evolution are not only human activities, including artificial recharge, but also natural factors, such as carbonate mineral dissolution. These factors control both the distribution and evolution trend of water quality. Urban nonpoint sources have a significant impact on groundwater quality. Based on the current water quality situation, it is urgent to strengthen protection of the ecological environment in the southern recharge area of the spring region and the water quality control in the western region.

“…Indeed, the study area is a large river basin with perennial river runoff in the northern Shandong Peninsula, playing an important role in regional economic growth [16]. The Shandong Peninsula, which is part of the Bohai Rim Economic Belt, is a major industrialized region in China [17]. In this coastal area, groundwater is one of the main sources used to meet industrial, agricultural and domestic drinking demands.…”

“…Hou et al (2014) [16] observed slight nitrogen pollution levels in the shoreline of the Dagujia river basin caused by land use classes. Zhu et al (2020) [15] assessed the impacts of various factors on pore water quality and pollution, whereas Gao et al (2021) [17] used graphical methods to evaluate the Quaternary aquifer and its controlling factors. These studies showed that the deterioration of the groundwater is mainly due to seawater intrusion and human activities.…”

“…These studies showed that the deterioration of the groundwater is mainly due to seawater intrusion and human activities. Moreover, several studies have indicated that seawater intrusion is a complex process for both alluvial pore and bedrock fissure aquifers, which may involve saline water mixing, water-rock interactions and hydrogeochemical reactions [4,17]. According to a review of the related literature, earlier research of this basin mainly focused on the pore water aquifers near the coastal region without comprehensively investigating the hydrochemical characteristics and evolution of groundwater of the pore water and bedrock aquifers [2,[15][16][17].…”

Groundwater resource is vital for industrial, drinking and irrigation purposes in the Dagujia river basin, China. The objective of this work was to comprehensively assess the hydrochemical characteristics and evolution processes of the Quaternary aquifer (QA) and the bedrock aquifer (BA) of the basin using statistical methods and hydrochemical plots. In total, 56 groundwater samples were collected from the QA (34 samples) and BA (22 samples). In addition, statistical methods combined with the geographic information system were used to identify the hydrochemical parameters of groundwater, as well as its spatial distribution in the Dagujia river basin. The Piper diagram showed that Ca-Na-HCO3 was the dominant groundwater facies type, while nine QA samples collected near the coastal line showed the Na-Cl facies type. On the other hand, the Gibbs diagram showed that most samples fell in the rock dominance zone. The principal component analysis results showed that the water–rock interaction and anthropogenic activities are the controlling factors, which is consistent with the results obtained using other methods. The results of this study indicated that rock weathering controls the hydrochemical characteristics of groundwater, while anthropogenic contamination and sea water intrusion are becoming increasingly serious issues for both QA and BA in the Dagujia river basin. Therefore, both Quaternary and bedrock aquifers require more attention.
