A 69-day hydraulic capture test was conducted in Tugou section of the Beiyun River Basin. The results showed that the groundwater level drawdown and influence radius of 20 m aquifers were 2 m and 80.2m, while those of 60m aquifers were 1.54m and 150.6m. During the test period, the concentration of most groundwater quality indicators showed a downward trend, of which sulfate concentration decreased by 57.9%, and the concentration of trace organic pollutant, phthalate ester(2-ethylhexyl), decreased by 96.3%. The change of pollutant concentration was closely related to dilution, cation exchange adsorption and clay mineral adsorption in aquifer media. The test results show that the hydraulic capture test can effectively control and remedy groundwater pollution.
