Fuzzy model for determination and assessment of groundwater quality in the city of Zrenjanin, Serbia

The application of the fuzzy logic for determination and assessment of the chemical quality of groundwater for drinking purposes in the city of Zrenjanin is presented in this paper. The degree of certainty and uncertainties is one of the problems in the most commonly used methods for assessing the water quality. Fuzzy logic can successfully handle these problems. Evaluation of fuzzy model was carried out on the samples from two representative wells that are located at depths of two aquifers from which water is taken to supply the population with drinking water. The samples were analyzed at 8 different chemical water quality parameters. In the research, the arsenic concentration (As3+ and As5+) is considered as the dominant parameter due to its suspecting carcinogenic effects on human health. This type of research is for the first time conducted in the city of Zrenjanin, middle Banat region.
