Assessment the Quality of Bottled Drinking Water Through Mamdani Fuzzy Water Quality Index

In this investigation, an innovative index was developed based on the fuzzy inference system for assessing quality of bottled drinking waters. A method to aggregate values obtained from defuzzification step. total number 24 parameters revealing characteristics were in terms physiochemical, dietary, toxic, and pathogenic aspects selected as input parameters. 30 samples taken independent brands found Hamadan province retail market evaluate water (BWQI). Results show that measuring are range standard levels set by national regulations. The BWQI scores 61.2-73.8 attributing marginal fair descriptive classes. had better because low contents NO3, NO2, Fe, Mn, Cu, Zn subjugated public distribution systems having severe standards urban treatment plants case safe water. mineral examination indicated they generally affected sedimentary rocks NO3 leaks fertilizers used agricultural doings also do not elaborate rigorous scrutiny alike those donned systems. Sensitivity analysis using Monte Carlo algorithm reveals Na, hardness, NO2 have most impact scores.
