“…The distribution of water resources in China is extremely unbalanced. Water resources are more plentiful, and the average annual precipitation is much higher, in coastal areas than in inland areas [79]. The main receivers of Gansu's virtual water exports include Zhejiang, Guangdong and other water-abundant areas, as well as Inner Mongolia, Chongqing, Shaanxi; all regions with more water storage than Gansu [72,80].…”

The concept of virtual water, as a new approach for addressing water shortage and safety issues, can be applied to support sustainable development in water-scarce regions. Using the input-output method, the direct and the complete water use coefficients of industries categorized as primary, secondary, or tertiary, and the spatial flow patterns of the inter-provincial trade in the Gansu province region of China, were explored. The results show that in 2007, 2010, and 2012 the direct and complete water use coefficients of the primary industries were the greatest among the three industry categories, with direct water use coefficients of 1545.58, 882.28, and 762.16, respectively, and complete water use coefficients of 1692.22, 1005.38, and 873.44, respectively; whereas, the direct and complete water use coefficient values of the tertiary industry category were the lowest, with direct water use coefficients of 16.65, 7.74, and 66.89 for 2007, 2010, and 2012, respectively, and complete water use coefficients of 65.46, 66.89, and 72.81 for 2007, 2010, and 2012, respectively. In addition, study results suggest that the volume of virtual water supplied to Gasnu province’s local industries has decreased annually, while virtual water exports from the province have increased annually, with the primary industry accounting for 95% of virtual water output. Overall, the virtual water of Gansu province in 2010 showed a net output trend, with a total output of 0.506 billion m3, while in 2007 and 2012 it showed a net input trend with a total input of 0.104 and 1.235 billion m3, respectively. Beijing, Shanghai, Guangdong, Ningxia and other water-scarce areas were the main input, or import source for Gansu’s virtual water; during the years studied, these provinces imported more than 50 million m3 individually. Based on these results, it is clear that under the current structure, virtual water is mainly exported to the well-developed coastal areas and their adjacent provinces or other water-abundant regions. Therefore, Gansu province should (1) adjust the industrial structure and develop water-saving and high-tech industries; (2) adjust the current trade pattern to reduce virtual water output while increasing its input to achieve balanced economic development and water resource security.

“…Health risk assessment consists of four phases like (I) Identification of risk, (II) Assessment of Dosage, (III) Exposure valuation, and (IV) Hazard characterization are recommended US environmental protection agency (Narsimha and Rajitha 2018; Li and Qian 2018).…”

“…Groundwater is widely used for drinking, agriculture, and industrial purposes (Adimalla and Wu 2019; Wu and Sun 2016). Over around world application of groundwater for drinking and irrigation purpose in the arid and semiarid region is increasing considerably, and 1.5 billion people rely on groundwater for irrigation and drinking purpose (Li and Qian 2018;Adimalla et al 2019c;Qian and Li 2011;Qian et al 2012;Adimalla and Qian 2019b;Wu et al 2014Wu et al , 2017Zhang et al 2018). In India, especially in Andhra Pradesh, numerous studies have been carried out on assessment of groundwater quality for drinking and irrigation purpose, such as (Sunitha and Sudharshan Reddy 2019;Subba Rao et al 2015Adimalla and Wu 2019;Sudharshan Reddy et al 2018;Muralidhara Reddy et al 2019) and 90% of the Urban and rural areas depend purely on groundwater for drinking domestic purposes.…”

Monitoring of groundwater quality for drinking purposes using the WQI method and its health implications around inactive mines in Vemula-Vempalli region, Kadapa District, South India

A study was conducted to evaluate the groundwater quality and health risk assessment for drinking purposes around inactive mining areas in the rural regions of Vemula-Vempalli region using the water quality index (WQI) method. For this study, forty groundwater samples were collected from bore wells and analyzed for physical parameters and major cations and anions followed by standard methods of APHA. From the analytical results, most of the groundwater samples are in alkaline nature; EC, TDS, and TH values are below the permissible limit and major cations (Ca 2+ , Mg 2+ , K + , Na +) & anions (Cl − , HCO 3 , SO 4 2− , F − , NO 3 −) also within the permissible limit except fluoride and nitrate. Fluoride and nitrate in the groundwater range between 0.24-3 and 0.14-269 mg/L, respectively. Magmatic intrusions and water-rock interactions are main responsible for elevated fluoride in groundwater, and agricultural practices and usage of fertilizer are major responsible for higher nitrates in the groundwater. Piper diagram reveals that most of the samples belong to hydrochemical facies Ca 2+-Mg 2+-HCO 3 − category in this region. A higher concentration of fluoride and nitrate in the groundwater may cause a serious impact on human health. Non-carcinogenic effects of F − and NO 3 − were computed using total hazard index by adopting USEPA guidelines; THI values in drinking water range from 0.41 to 7.28 (adults), 0.41 to 7.38 (children) and 0.31 to 5.62 (infants); it reveals that children are more prone to the health impact than adults and infants. Overall assessment of WQI values (83.7-186.1 mg/L) shows that 7.5% (excellent), 80% (good), and 12.5% groundwater samples are very poor for drinking purpose in this region.

“…Groundwater is extensively used for agricultural, industrial, and drinking purposes in many arid and semi-arid regions (e.g., Western United States, Algeria, Egypt, China, and Australia) where rainfall is infrequent and surface water is scarce [1,2,3,4]. Groundwater accounts for only 29.9% of all global freshwater resources [1,5], and water resource shortages have become one of the most important challenges to humankind [4,6].…”

To investigate the quality of domestic groundwater and assess its risk to inhabitants of the Guanzhong Basin, China, 191 groundwater samples were collected to analyze major ions, nitrate, pH, total dissolved solids (TDS), total hardness (TH), and electrical conductivity (EC). The physiochemical parameters, hydrochemical facies, and sources of major ions were analyzed using Durov diagrams, bivariate diagrams, and chloro-alkaline indices (CAI-I and CAI-II). The suitability of groundwater for drinking, the nitrate distribution, and human health risk (HHR) for different age groups were evaluated. The results showed that the relative abundance of cations in the groundwater samples was K++Na+ > Ca2+ > Mg2+, while that of anions was HCO3− > SO42− > Cl− > NO3−. Groundwater samples mainly contained HCO3-Na and HCO3-Ca, which were introduced mainly by rock weathering and ion exchange. The groundwater in the Guanzhong Basin contained mainly good and medium water, and the groundwater in the southern part of the Wei River was better than that north of the Wei River. Areas containing high nitrate concentrations were mainly located in the central and western parts of the Guanzhong Basin. The percentages of low risk (<45 mg/L), high risk (45–100 mg/L), and very high risk (>100 mg/L) of nitrate pollution in the study area were 90.58%, 8.9%, and 0.52%, respectively. The HHR assessment results indicated that people in the 6–12 month age group were more likely to suffer from health complications due to a higher nitrate concentration, followed by 6–11 years, 21–65 years, 18–21 years, ≥65 years, 11–16 years, and 16–18 years age groups, which was mainly due to the different exposure parameters. The results of this study will be useful in regional groundwater management and protection.
