Background values of groundwater are the core basis for groundwater environmental management in in-situ leaching uranium mine. Aiming at the characteristics of large sample size, strong discreteness and high spatial heterogeneity in background values monitoring of groundwater during the construction period of an in-situ leaching uranium mine, this paper established a background values determination method consisting of Grubbs outlier test, manual review, data distribution type judgment, and values range & mean calculation. A case study was carried out in mining area 1 # to obtain the background values and spatial distribution characteristics of groundwater characteristic factors. This method can effectively distinguish natural high concentration values from man-made abnormal values with objective and representative results. It can provide technical support for groundwater environmental management of in-situ leaching uranium mines and also serve as a technical reference for background values determination of similar uranium mines.
