Groundwater pollution assessment in the plain area of Fengtai District
摘要
Abstract
This paper employs the pollution index method to assess groundwater contamination in the Fengtai plain area.In order to reflect both the cumulative impact of long-term pollution and the outcomes of recent remediation efforts,this study innovatively uses early historical data(1954-1963)and recent historical data(2010)as reference values for conducting long-term and short-term pollution assessments,respectively.The results show that compared with the long-term assessment,the short-term assessment reveals a significant improvement in groundwater quality:the dominant pollution grades of total hardness and nitrate nitrogen shift from moderate/heavy pollution to non-polluted;the dominant grade of total dissolved solids changes from moderate pollution to non-polluted;and the comprehensive groundwater pollution grade also shifts from moderate/heavy pollution to non-polluted.Areas classified as extremely heavy pollution in the long-term assessment are rated as moderate pollution in the short-term assessment.Zones identified as severely and heavily polluted in the long-term assessment are mostly categorized as lightly polluted or non-polluted in the short-term assessment,while areas with moderate or light pollution in the long-term assessment are generally non-polluted in the short-term assessment.The combination of the both assessment approaches provides a more comprehensive and objective reflection of the groundwater pollution status.关键词
