The Study of chemical quality of groundwater in Khorramabad area, Lorestan Province

Khorramabad plain is located in folded Zagros in classification of structural geology. The investigations of hydrochemical results in this area show that groundwater is calcic bicarbonate to magnesium type and water quality is suitable for drinking and agriculture. But according to composition of geological formation (chalky-salty Gachsaran and Limeston Sarvak, Ilam, Asmari Formation) in this area, the quality of karstic resources and reserves is vulnerable. Also this studies show that most of the elements (except for Ammonia amount in some samples and Fluorine) in groundwater occurred in the world standard global range and have not problem in regard to environmental geology.
