Comprehensive Evaluation on Groundwater Environmental Quality in Jinghe Xincheng of Shaanxi Xixian New District
摘要
Abstract
According to the field investigation on groundwater environment at Jinghe Xincheng of Xixian New District in Shaanxi Province, F value method and the improved Nemerow index method, these two composite index methods were adopted, and total hardness, total dissolved solids, sulfate, chloride, potassium permanganate index, nitrate, nitrite, ammonia, fluoride, arsenic and chromium ( Cr6+) , these 11 evaluation indexes were chosen to conduct a comprehensive analysis and evaluation on 11 groundwater samples about the groundwater environmental quality. The results show that the impact of the maximum contamination factor of F value method is highlighted, which affects the overall result; as the improved Nemerow index method considers the weights of evaluation index, so the influence of the maximum contamination factor is decreased, which makes the evaluation results more objective and accurate; the mainly excessive indexes in this research area are nitrates, sulfates, dissolved solids, total hardness, fluoride, chloride and hexavalent chromium ( Cr6+); the overall condition of groundwater environment quality is poor in the area.关键词
