Nowadays there is a serious problem of groundwater conservation from contaminants that get into aquifers due to human activity. This problem is especially acute in industrial and agricultural regions. In order to solve the problem of groundwater conservation from contaminants it is necessary to hold activities for possible contamination forecasting. One of such activities is evaluation of groundwater vulnerability degree. The given article describes different evaluation methods of groundwater vulnerability developed in different countries and predominantly applied in the world. The given methods use different amount of geological and hydrogeological characteristics for vulnerability evaluation, thereby some methods are easily applicable while the others require more labor costs. The choice will depend on goals and objectives set by a researcher.
