“…2009), and the waste water from them is discharged into the network of sewer pipe and finally to the treatment plant. During this process, leakage of wastewater to the subsurface is inevitable due to the broken or malfunctioning pipelines (Qian et al 2011), especially in an old town. In this case, more wastewater will enter into the groundwater in the wet season than in the dry season due to the abundant rainwater in wet season, which implies the anthropogenic source for high concentrations of Co, Cr, Al in groundwater of the study area.…”

“…In recent years, the studies related to metals in groundwater were mainly focused on the hydrochemical assessment and the relationship between metals and other chemical parameters with multivariable statistical analysis (Helena et al 2000;Edet et al 2003;Chen et al 2007;Qian et al 2010Qian et al , 2011Zhang et al 2012). A handful of studies discussed the seasonal influence on the metals in groundwater (Leung and Jiao 2006;Buragohain et al 2010).…”

The present study is aimed at assessing the water quality and discussing the hydrochemical characteristics and seasonal variation of shallow groundwater on the aspect of metals in the eastern Chancheng district of Foshan city, south China. Multivariate analytical methods such as principal components analysis (PCA) and hierarchical cluster analysis (HCA) were used in this study. The results show that 45% of groundwater in the east-central of study area is not suitable for drinking purpose due to high concentrations of Fe, Pb and Mn. The mean concentrations of Fe, Hg, Cu, Pb, and Mn in dry season are higher than that in wet season. On the contrary, the mean concentrations of Cd, Co, Zn, Ba, Cr, Mo, Ni and Al in wet season are higher than that in dry season. PCA results show that four PCs are responsible for the 78.6% of the total hydrochemical variables in groundwater. Three groups were generated from HCA method. Group 1 reflects the characteristic of wet season and the low ion exchange capacity; group 2 is mainly influenced by the dry season. Reducing environment and high ion exchange capacity are responsible for group 3. The results are useful in addressing future measures in groundwater resource management for local government.

“…Many factors influence the nitrate pollution in groundwater, such as the land uses (agricultural land, village, town center, poultry factory, etc.) (Guo et al 2004;Hu et al 2005;Hou et al 2014;Qian et al 2011), fertilizers and irrigation used in agricultural activities (Eickhout et al 2006), soil property (Huang et al 2014), and hydrogeochemical processes in water-rock interaction. Several approaches were used in previous studies to evaluate the nitrate contamination in groundwater, such as nitrogen isotope analyses (Lzbixki 2014) and GIS-based approaches (Wang and Yang 2008).…”

The study of NO3 (-) contamination in groundwater is becoming increasingly significant as high concentrations of NO3 (-) in groundwater can do damage to public health. Nitrate pollution in the shallow, middle-deep and deep aquifers in the urban district of Zhanjiang was studied using the ordinary Kriging interpolation method combined with hydrochemical and correlation analyses in 2011. The results showed NO3 (-) pollution was present in the shallow groundwater, with average concentrations of 47.43 mg/L and standard deviation of 50.92. Nitrate concentrations were lower in middle-deep and deep aquifers, with average concentrations of 2.36, 0.80 mg/L, and standard deviation of 6.23, 0.93, respectively. Nitrate was correlated with Na(+) + K(+), Mg(2+), Cl(-) and SO4 (2-) in the shallow aquifer, and the spatial distributions of NO3 (-) exhibited a same pattern with TDS in the shallow aquifer, the NO3 (-) pollution in the middle-deep and deep aquifers is less serious.
