Results show that the evaluation basically and objectively reflected the status of the groundwater environment in the region and determined sources and degree of the pollution of the groundwater, which demonstrates that the set of methods is target-oriented and operable. Their The establishment of the methods is of great significance to guiding nationwide investigation and evaluation of status of groundwater environment in such regions.
