Key problems of the groundwater environmental assessment for petrochemical projects in littoral zones

Owing to the concealment and retardation of groundwater contamination,especially for the petrochemical projects with the pollution characteristics as multi-type,high environmental risk,illegible protect-object,the assessment of original groundwater environment is important. Based on the analysis of the large-scale petrochemical project on the littoral zone of the Pearl River Delta,this paper gives the exploratory-discussion of the determination of the protect-object and assessing standard of gro...
