| Groundwater Contamination Assessment and Analysis of Contamination Factors of Songyuan City in Jilin Province |
| Songyuan is a new city of petrochemical industry base in northern China. The development of petrochemical industry has caused a certain degree of contamination of groundwater in the area. On the basis of regional hydrogeological investigation, the authors assessed present situation of groundwater contamination by using single factor evaluation and superposition index method and analyzed the influence of contamination on the groundwater. The concentrations of Fe, Mn and NH4+ in the groundwater are much higher than their standards, mainly associated with high background values of the original environment. Most areas of the city have been slightly polluted, and local seriously and relatively heavily polluted districts assume point or zonal distribution. The total hardness and mineralization degree of groundwater also seriously exceed the standard values. In local heavily polluted places, the concentrations of Cl, SO42–, NO3–, COD and volatile phenol in the water also exceed the standard values. The groundwater pollution is closely related to the oil extraction, refining, processing and transportation in addition to human life pollution. |
