Investigation and Evaluation of Groundwater Contamination in a Petrochemical Enterprise in North China
With the rapid development of industriali-zation,the problem of groundwater pollution has be-come increasingly prominent. The investigation and evaluation of groundwater pollution is the basic work to understand the status of groundwater quality,pol-lution sources,pollution scope and pollution degree. A petrochemical enterprise in North China was select-ed as the research object,and the groundwater sam-pling analysis was carried out by single index evalua-tion method. It was found that petroleum,petroleum hydrocarbons,dissolved total solids,iron,ammonia nitrogen,sodium,cadmium,lead and other factors exceeded the corresponding standard limits. Com-bined with the analysis of production technology and raw and auxiliary materials,it was speculated that the phenomenon of exceeding the standard was related to the early production activities of the enterprises loca-ted in the site. This study provided data support for the pollution control of the investigation enterprises,and also provided reference for the investigation and evaluation of similar petrochemical sites.
