Research on Chemical Types and Genetic Mechanism of Groundwater in Yiluo Basin

Groundwater and its geological functions are closely related to human life economic construction. The quality of groundwater is great significance for maintaining the development national economy daily residents in region. Understanding chemical characteristics genesis mechanism a certain area helpful provide important basis sustainable resources this area. This study mainly aimed at Yiluo Basin, piedmont basin western part Henan Province. According composition shallow groundwater, was systematically analyzed by using ionic scale coefficient, Piper three-line diagram, Kriging interpolation method Shukarev classification. Finally, hydrogeochemical simulation software PHREEQC used reverse fluoride ions results were discussed, revealing existence state groundwater.
