Abstract:

Based on the analysis of hydrogeological condition around a contaminated site, groundwater samples from 17 monitoring spots in the study area were tested.Quality of groundwater environmental was assessed by choosing 17 assessment factors of environmental quality, appling Single Factor Evaluation, Comprehensive Index Evaluation and Fuzzy Comprehensive Evaluation, and taking the Quality Standard for Groundwater(GB/T14848-93) as the standard.Results indicated that N-NH3, SO2-4, total hardness, pH, Cr, Mn and As had exceeded the criterion, and groundwater quality in the study area was seriously contaminated.Such a groundwater deterioration was probably due to the landfills, petrol station and urban sewage drainage in the northern and southern regions of the study area.

Key words: groundwater, environmental quality assessment, single factor evaluation, comprehensive index evaluation, Fuzzy Comprehensive Evaluation
