“…Heavy metals are constant in the natural environment. Their persistent properties make these contaminants accumulate in the body and threaten human health [10,11]. Some heavy metals cause damage to the nervous system, inhibit the enzymes in the body, and damage detoxification organs [11].…”

Population growth affects the need for water which increases in quantity, followed by an increase in quality and continuity. The development of anthropogenic activities, agriculture, industry, and domestic resulted in a declining rate of clean water in Bandung District, especially in three areas, namely Ciparay, Dayeuhkolot and Margaasih sub-districts. Analysis samples of groundwater in South Bandung District showed an average pollution index of 11.42, which is included in the category of heavily polluted. Therefore, a public health risk assessment is carried out due to groundwater resources for hygiene and sanitation use. Risk characterization is carried out by quantitative methods of calculating the value of the Hazard Index with Monte-Carlo simulation analysis. Spatial analysis is carried out to show the range of risks that can be exposed to the community in the area. Spatial analysis can describe the effect of groundwater pollution and land use on health risk by calculating elevation on the Inverse Distance Weighted interpolation method in Geographic Information System Software. The Hazard Index value categorized child and adult values in each area, with spatial analysis resulting in high – low gradation. Range of hazard index show for Child – Ciparay and Adult – Ciparay respectively 1.15 – 0.08 and 1.16 – 0.22, for Child – Dayeuhkolot and Adult – Dayeuhkolot respectively 0.77 – 0.04 and 0.69 – 0.08, and for Child – Margaasih and Adult – Margaasih respectively 0.47 – 0.11 and 0.55– 0.14. Dermal exposure due to groundwater showed a non-carcinogenic risk in Ciparay Area in the Agriculture land use. Therefore, the stakeholder must periodically evaluate groundwater quality as hygiene and sanitation water, and the land use masterplan and management must be revised to reduce public health risks.

“…Spearman correlation analysis is widely used in the data of non-normal distribution hydrochemical processes, and the linear correlation between two parameters can be evaluated. The closer the correlation coefficient is to 1, the stronger the correlation between the two parameters, and the more likely they are to have the same source [ 28 ]. Principal component analysis (PCA) is a statistical method that can simplify and merge several original variables through dimension reduction.…”

Heavy metals pollution in groundwater and the resulting health risks have always been an environmental research hotspot. However, the available information regarding this topic and associated methods is still limited. This study collected 98 groundwater samples from a typical agricultural area of Songnen Plain in different seasons. The pollution status and sources of ten heavy metals (As, Ba, Cd, Co, Cr (VI), Cu, Fe, Mn, Ni, Pb, and Zn) were then analyzed and compared. In addition, the human health risks assessment (HHRA) model was used to calculate human health risks caused by heavy metals in groundwater. The results revealed that heavy metals were mainly distributed in the northwest of the study area and along the upper reaches of the Lalin river and that the concentrations of heavy metals were higher during the wet season than the dry season. Industrial and agricultural activities and natural leaching are the main sources, and each kind of heavy metal may have different sources. Fe and Mn are the primary pollutants, mainly caused by the native environment and agricultural activities. The exceeding standard rates are 71.74% and 61.54%, respectively based on the Class III of Quality Standard for Groundwater of China (GB/T 14848-2017). The maximum exceeding multiple are 91.45 and 32.05, respectively. The health risks of heavy metals borne by different groups of people were as follows: child > elder > young > adult. Carcinogenic heavy metals contribute to the main risks, and the largest risks sources are Cr and As. Therefore, the government should appropriately restrict the use of pesticides and fertilizers, strictly manage the discharge of enterprises, and control man-made heavy metals from the source. In addition, centralized water supply and treatment facilities shall be established to prevent the harm of native heavy metals.

“…The hydrogen and oxygen stable isotope compositions of various water bodies have extensive spatiotemporal heterogeneity [50,51]. Without high-temperature water-rock interactions and strong evaporation, 2 H and 18 O isotopes are considered to be conserved and stable in the environment [52,53]. Therefore, stable isotopes of hydrogen and oxygen can indicate the formation, migration, and evolution processes of groundwater.…”

Coastal groundwater is an important resource in the developed region associated with human health and sustainable economic development. To identify the origins of salinity and evaluate the impact of water-rock interactions, seawater intrusion (SWI), and evaporation on groundwater in the coastal areas of Zhejiang and Fujian provinces, a comprehensive investigation was performed. Meanwhile, nitrate and fluoride indicators resulting from the anthropogenic activity and SWI were also considered. At last, the water quality index (WQI) of coastal groundwater was evaluated with geochemical and multivariate statistical methods. The results indicated that (1) the groundwater in coastal areas of Zhejiang and Fujian provinces has been affected by SWI to varying degrees. The analysis of selected ion ratios (Na+/Cl− and Br−/Cl−) and isotopic compositions showed that SWI is the predominant cause of increasing salinity in the groundwater of Zhejiang Province, while the cause is water-rock interactions (ion exchange and mineral weathering) in Fujian Province. The hydrochemical evolution path of groundwater in Zhejiang Province is Ca/Mg-HCO3 to Na-Cl, while a different pattern of Ca/Mg-HCO3 to Na (Mg/Ca)-Cl occurs in Fujian Province. However, the trend of SWI development in both provinces was freshening. (2) Nitrification, sewage infiltration, and SWI increased the NO3− content in groundwater. Some of the NO3− concentration in Fujian Province exceeds the standard, and the nitrogen pollution was more serious than in Zhejiang Province. The F− content in coastal groundwater was affected by SWI and mineral dissolution; the F− content in Zhejiang Province was higher than in Fujian Province, which was close to the groundwater standard limit. The average WQI value of Zhejiang was 103.61, and the WQI of Fujian was 61.69, indicating that the coastal groundwater quality in Fujian Province was better than in Zhejiang Province. The results of the study revealed the impact of SWI and anthropogenic activity on groundwater in the southern coastal zone of China and will be valuable for sustainable groundwater resource management.
