“…Water quality assessment is indispensable because water quality is essential to human health and the process of industrial production. The result of water quality assessment is mostly based on the established quality standards (Hua et al, 2010;Hua et al, 2011). For example, the World Health Organization (WHO) recently published the fourth edition of guidelines for drinking water to protect public health (WHO, 2011), with many countries-such as the United States, Canada, and Australiafollowing suit (U.S. EPA, 2011;Health Canada, 2012;NHMRC and NRMMC, 2011).…”

Groundwater quality is the critical factor that affects human health and the quality of industrial products in Foshan City, South China. Multivariate statistical techniques, including hierarchical cluster analysis (HCA) and principal component analysis (PCA), were applied to evaluate and interpret the complex groundwater quality in eastern Chancheng district, Foshan City. During the dry and wet seasons, 60% and 11% of the total groundwater samples (respectively) are suitable for drinking purposes; other samples can be used for drinking after being treated for pH, Fe, Mn, Al, NH4, and NO3. Similarly, during the dry and wet seasons, 75% and 33% of the total groundwater samples (respectively) are suitable for industrial purposes; other samples can be used for industrial purposes after being treated for NH4 and NO3. Five principal components are extracted from PCA and used to explain 81.78% of the variance in groundwater. The indicators to groundwater quality assessment are EC, Na, Cl, Fe, Mn, NH4, pH, Eh, PO4, HCO3, and K from PCA. HCA reveals that groundwater samples in the study area can be classified into three groups: one reflecting the interaction of groundwater and sediment medium along with the role of cation exchange; another reflecting the role of anion exchange between phosphate and carbonate; and the final reflecting the reducing environment.

“…In recent years, the use of groundwater for the area's water supply has been limited by increased contamination of the aquifers (Guo and Wang, 2005). Thus, groundwater safety and quality management has become increasingly important for sustainable development of these regions (Guo and Wang, 2004;Hua et al, 2010). Hydrogeological and geochemical studies provide essential data for sound scientific groundwater management.…”

The Jinghuiqu irrigation district is located in the semi-arid regions of northwestern China, where groundwater is the most important natural source for local industry, agriculture and residents. The present work was conducted in the Jinghuiqu irrigation district to characterize the groundwater aquifer, which has undergone long-term flood irrigation for over 2000 years. Isotopic and hydrochemical analyses, along with geological and hydrogeological tools, were used to determine the chemical properties and evolutionary processes of the groundwater aquifer. Results showed that the groundwater chemistry had changed significantly from 1990 to 2009. Water with concentrations of CaMgSO4 had decreased significantly, from 60% to 28% of the total water samples, during the period, while water with concentrations of NaSO4 and NaCl increased significantly, from 28% to 72%. The salinity of the groundwater increased rapidly and the affected area had expanded to most of the irrigation district. Stable isotope studies showed that most of the groundwater concentrations were derived from sulfate mineral dissolution. The minerals saturation indices (SI), ion ratios and oxygen isotope values of the groundwater indicated that the shallow groundwater had mainly experienced mineral dissolution, cation exchange, and mixing of the irrigated surface waters and groundwater. The groundwater quality had continuously evolved toward salinization as concentrations of SO4(2-) and Na+ grew to dominate it. Water quality risk analyses showed that most of the saline groundwater is not suitable for domestic and irrigation uses, especially in the middle and eastern parts of the irrigation district. These findings indicate that the irrigation district should strengthen the groundwater resources management.
