Abstract
Abstract
At present, many fuzzy logic techniques have been developed, however, there is a lack of studies concerning the application of improved techniques to evaluate groundwater quality in comparison to traditional methods. In this study, a set of sample data for nine items (total hardness, total dissolved solids, SO43−, NO3−, total Fe, F−, Pb, pH, and turbidity) was adopted for developing an improved fuzzy logic technique in order to evaluate groundwater quality status. The evaluation results were classified into five grades according to a standard for groundwater quality(GB/T 14848 − 2017), to determine the suitability groundwater use. The results showed that the quality of the groundwater samples was mostly within Grades 1 and 2, making the water suitable for a variety of uses. Traditional analysis found the groundwater quality was mostly within Grade 5. Improved fuzzy logic techniques were shown to be helpful for future research related to groundwater quality evaluation.
