Reusing water from sources like air conditioner condensate is important. Since there is little information about its quality and safety for irrigation or drinking, evaluating the water’s quality and safety for reuse through advanced methods like Monte Carlo simulation is essential. </span> <strong><span>Methods:</span></strong><span> Samples were collected in triplicate from 30 air conditioning units to enhance reliability of the data. Chemical analyses measured pH, total dissolved solids (TDS), electrical conductivity (EC), hardness, and specific ions (chloride, sodium (Na), calcium (Ca), magnesium (Mg)). SPSS alongside Monte Carlo simulation were utilized to assess variability and potential risks associated with water reuse. </span> <strong><span>Results:</span></strong><span> The water quality analysis of the condensate revealed an average chloride concentration of 51.91 mg/L, Na at 67.49 mg/L, Ca at 14.37 mg/L, and Mg at 20.01 mg/L. Temporary hardness averaged 127.23 mg/L as CaCO₃, permanent hardness 178.38 mg/L as CaCO₃, and total hardness (TH) reached 305.62 mg/L as CaCO₃. TDS were measured at 196.15 mg/L, EC at 296.74 μS/cm, and the pH was slightly alkaline at 7.13. Based on the histogram of water quality index (WQI), the WQI values of the samples ranged between 32.14 and 126.6. This is equivalent to “Moderate” to “Poor” quality water. </span> <strong><span>Conclusion:</span></strong><span> The results indicate high potential for reuse of such a water source, especially for non-potable purposes such as irrigation. Detailed further studies are, however, required to properly evaluate its safety, treatment requirements, and suitability for larger applications.</span> https://jaehr.muk.ac.ir/article_242848_20896751e7c62fc6f6cfc1d87f8674dc.pdf
