China Environmental Science, 2015,35(9) ：2843~2852 Abstract ：In order to give a basis for the assessment, the remediation and the treatment of groundwater contaminations, the groundwater pollutants from MSWLs were identified by cumulative pollution load ratio; the groundwater quality near the MSWLs were assessed integrally by Nemero index method and grading methods based on authors′ survey and related reports from 1991 to 2014. The results showed that there were 99 kinds of groundwater pollutants, 2 kinds of visual pollutants and 6 kinds of aggregative pollutants which had been detected. The widespread groundwater pollutants include ammonia, nitrate, nitrite, permanganate index, chemical oxygen demand, total hardness, chloride, iron, manganese, total coliform and volatile
