Abstract In this study, hydrogeochemical processes controlling groundwater chemistry and quality were investigated. Drinking water is supplied from (mostly spring well water) in the study area. The various parameters such as physicochemical parameters, major ions, trace elements nitrogen derivatives of samples analyzed. These analysis results are compared with drinking standards for suitability...

Abstract Pindul cave located in Gunungkidul Regency, Gunungsewu Karst Area, Indonesia has a unique characteristic which is dominated by surface rivers (allogenic recharge) and groundwater (autogenic recharge). The main purpose of this study to analyze temporal variation flood water hydrogeochemistry Cave. Water sampling for analysis taken the wet season three selected events. Parameters consist...

In order to study hydrogeochemical effect in the process of seawater intrusion (SI), and provide scientific basis for comprehensive management water resources ecological restoration, Longkou city Shandong province China was taken as an example this study. Based on observed data, traditional hydrogeochemistry methods hydrochemistry analysis, correlation principal component reverse geochemical si...

Abstract Fluorosis is the most widespread and serious endemic disease in abandoned Yellow River flooding delta of East China. One important causes fluorosis drinking high-fluorine groundwater. In this study, 313 groundwater samples were collected central part to address chemistry high-fluoride groundwater, 33 core from one borehole 150 m depth analyse vertical distribution characteristics total...
