Agricultural production may cause groundwater pollution. This study investigated the characteristics of shallow pollution in a typical black land agricultural area Northeastern China and geochemical behavior major pollutants. A total 27 23 samples were collected for measuring on-site parameters components 2000 2014, respectively. The improved integrated approach was used to assess contamination...

We performed batch dissolution experiments on different sized granite and biotite in pure water, in order to better understand the source and geochemical behavior of fluoride in groundwater. Very high concentrations of fluoride (up to 6–10 mg/l) were observed from granite leaching. Correlations between leached ions suggest that fluoride possibly originates from dissolution of biotite. After ~50...

The chemical composition of groundwater in the Jordan Valley, along the section between the Sea of Galilee and the Dead Sea, is investigated in order to evaluate the origin of the groundwater resources and, in particular, to elucidate the role of deep brines on the chemical composition of the regional groundwater resources in the Jordan Valley. Samples were collected from shallow groundwater in...

Thirty water wells were sampled in 2018 to understand the geochemistry and age of groundwater Williston Basin assess potential effects shale-oil production from Three Forks-Bakken petroleum system (TBPS) on quality. Two geochemical groups are identified using hierarchical cluster analysis. Group 1 represents younger (median 4He = 21.49 × 10?8 cm3 STP/g), less chemically evolved water. 2 older 1...

The purpose of this study was to consider the effectiveness of two methods of restoring groundwater quality in a subsurface uranium-bearing formation following in situ leach (ISL) mining. To accomplish this it was necessary to develop an understanding of the geochemical characteristics of an aqueous solution that might be produced by an ISL mine. Samples of material from three different uranium...
