| Abstract: | Combined groundwater quality standards（GB/T14848-93）evaluation criteria, eight kinds of typical contaminants was selected as evaluation factors. Using the improved Nemerow methods which have considered the maximum weights, and combined with a more objective entropy method to determine the weights of the evaluation factors, 16 groundwater environmental quality of water samples of Huainan were evaluated. Evaluation results can distinguish quality reasonably and respond to water quality more objectively. |
