THE Cr( VI) POLLUTION CHARACTERISTICS OF GROUNDWATER AND SOIL IN THE SURROUNDINGS OF A CHROMIUM SLAG SITE

Soil and groundwater samples in different distances and depth were taken from the surroundings of a chromium slag site to explore the Cr( VI) distribution and pollution characteristics． Based on large amount of data，the contaminating ranges and degrees of groundwater and soil were determined and the polluted boundary was confirmed，which provided basic data for the pollution treatment． The results demonstrated that the surrounding soil and groundwater of the chromium slag site were contaminated seriously by Cr( VI) ． Effective measures should be taken as soon as possible to control pollution in the said site to ensure the local agricultural production and human health．
