Abstract: Pollutants will infiltrate into groundwater through the aeration zone when pollution accidents occur during the storage and transportation of petrochemical products. This will affect the groundwater quality. Through forecasting, formulating scientific groundwater control measures is effective means to prevent the impacts of the project on the groundwater environment. Taking a petrochemical construction project in Guangdong as an example, this paper predicts and evaluates the possible impacts of the project during operation period on the groundwater environment on the basis of ascertaining the hydrogeological conditions. Then it puts forward corresponding anti-seepage technical measures and predicts the effectiveness of these measures. The prediction results show that the influencing sphere of the pollution source intensity on groundwater is obviously reduced after anti-seepage measures are adopted, which indicates that anti-seepage measures can prevent pollutants from entering the groundwater and protect groundwater resources.
