“…The non-point sources, such as agricultural practices, and localized factors, such as sewage leakages, generally control nitrate concentration in surface- or shallow- level groundwater (Wang et al 2017 ). It has been observed that higher levels of contamination are mostly associated with shallow groundwater and are the result of cultivation models, manures, wastewater irrigation, redox conditions, precipitation surpluses, waste disposal networks, animal wastes, industry, river–aquifer interactions, denitrification, and related biogeochemical processes in groundwater (Jia et al 2020 ; Taufiq et al 2019 ; Zendehbad et al 2019 ). In the study area, farming activities and farm animals could be the biggest sources of nitrate in groundwater.…”

Anthropogenic factors are contaminating crystalline aquifers more rapidly than natural sources and affecting human health in many states in India. Since a large population depends on untreated groundwater, identifying the sources of this contamination and assessing the related human health risk are essential to ensure a good-quality water supply. Nitrate is one of the most widespread means of groundwater contamination in many parts of India. Coimbatore and Tirupur districts are the most rapidly growing industrial urban areas in southern India. This paper deals with nitrate contamination and possible health risks for children and adults in the Coimbatore and Tirupur districts based on 93 groundwater samples. To achieve this goal, classical hydrochemical and deterministic hazard identification methods coupled with spatial mapping technologies were applied. A wide variation in nitrate concentration, between 1 and 415 mg/L, was observed, with 37% of the samples exceeding the WHO permissible limit of 50 mg/L. The distinct concentrations of nitrate and other ions observed spatially can be attributed to the diverse geochemical and land use settings in the study area. The bivariate plots of NO3 with other ions suggested that the principal origin of nitrate in this study is related to the excess application of fertilizers and sewages. The spatial variation of NO3, in comparison with the land use map, confirmed these results. The values of hazard quotient (HQ) via ingestion exceeded the critical value, one in 40% in males, 42% in females, and 45% in children. However, HQ values via oral pathways are within one and pose no exposure risk. Thus, the hazard index corresponds to HQingestion only. The health risk was in the increasing order of male>female>children, and shows that body weight is the most critical factor that is influencing the health impact to children as compared to adults. The spatial variation of hazard index values showed that groundwater quality is highly polluted with NO3 in the north and northeastern parts of the study area, mainly due to intensive agricultural practices, and poses critical health concerns. Considering the increasing population and higher dependencies on groundwater, immediate and sufficient measures are proposed.

“…An increase in nitrate concentrations in aquifers may be explained as follows: (1) high nitrate in shallow groundwater aquifers might cause by nitrate infiltration from rice fields, polluted canals, and rivers, and fishery ponds, and (2) high nitrate concentrations observed in deep aquifers may be because of the leakage of nitrate sources through and along well casings. Likewise, high nitrate concentrations in groundwater were also found in many coastal aquifers such as in Tunisia (Ziadi et al 2019), China (Peng et al 2018), India (Rao et al 2017), Palestine (Abu Al Naeem et al 2019, Mexico (Mahlknech et al 2017), Malaysia (Narany et al 2018;Sefie et al 2018), and Indonesia (Taufiq et al 2019). This situation indicates that nitrate pollution has become a common problem in many coastal aquifers in the world.…”

Groundwater is a primary freshwater source for various domestic, industrial and agricultural purposes, especially in coastal regions where there are lacking surface water supply. However, groundwater quality in coastal regions is often threatened by seawater intrusion and contamination due to both anthropogenic activities and natural processes. Therefore, insights into groundwater geochemistry and occurrences are necessary for sustainable groundwater management in coastal regions. The main aim of this study is to investigate the hydrogeochemical characteristics and their influencing factors in a coastal area of the Mekong Delta, Vietnam (MD). A total of 286 groundwater samples were taken from shallow and deep aquifers for analyzing major ions and stable isotopes. The results show that deep groundwater is dominated by Ca-HCO 3 , Ca-Na-HCO 3 , Ca-Mg-Cl, and Na-HCO 3 while shallow groundwater is dominated by the Na-Cl water type. In this region, the main geochemical processes controlling groundwater chemistry are ion exchanges, mineralization and evaporation. Groundwater salinization in coastal aquifers of the Mekong Delta is caused by (1) paleoseawater intrusion and evaporation occurring in the Holocene and Pleistocene aquifers, (2) dissolution of salt sediment/rock and leakage of saline from upper to lower aquifers due to excessive groundwater exploitation and hydraulic connection. High nitrate concentrations in both shallow and deep aquifers are related to human activities. These results imply that groundwater extraction may exacerbate groundwater qualityrelated problems and suitable solutions for sustainable Electronic supplementary material The online version of this article (

“…Groundwater genesis can be seen from the composition of groundwater, and the processes occur when passing through aquifer media [9]. Research on hydrochemical and stable isotopes in hydrogeological systems at Bandung-Soreang and Batujajar Groundwater Basin has been widely carried out by several researchers [6,[11][12][13][14][15][16][17]. Previous isotope research for groundwater recharge in the Bandung Basin has been carried out based on groundwater type.…”

Groundwater Recharge Area Based on Hydrochemical and Environmental Isotopes Analysis in the South Bandung Volcanic Area

The determination of recharge areas needs to support the groundwater conservation in the southern volcanic Bandung area. This study aims to determine the recharge area based on environmental isotopes and hydrochemical. A sampling of 26 groundwater was carried out at springs, dug wells, and drilling wells. The variation in groundwater chemistry principally is controlled by a combination of ion exchange, silicate weathering, calcite, and dolomite dissolution of minerals. The hydrochemical facies were CaCl, CaMgCl, CaMgHCO3, CaHCO3, and NaKHCO3. The CaHCO3 facies describe moderate groundwater flows. The NaKHCO3 facies shows the mixing of shallow and deep groundwater. The recharge area in the central, proximal, and medial facies zone consists of 3 groups. Group I is considered water originating from local rainwater infiltration; Group II is considered the infiltration elevation which ranges from 980–1230 m asl; Group III estimated to be derived from the recharge elevation between 750–970 m asl, Group IV are more likely to show symptoms of evaporation or interaction with surface water. The discharge area is characterized by less active groundwater circulation, with dominant HCO3– and TDS value in the distal facies zone. Hydrochemical variation helped the identification of recharge areas in the volcanic facies.
