In this study, water samples were collected from four locations: a well, a tap, the Kharazi Valley, and the Tigris River. Samples were taken over three months—February, March, and April—and the following measurements were recorded: pH, TDS (Total dissolved solids), and temperature. The temperature of each water sample, measured during collection, ranged between 16°C and 25°C. The pH ranged from 7.3 to 8.8, while TDS reached the highest value in the river sample at 830, and for the other samples, a rangebetween 221 and 360 was recorded. The samples were then inoculated on corn meal agar (CMA). In February, Penicillium spp. was the most prominent fungus, appearing in 62% of samples. In March, the yeast Candida spp. was the most common at 36%, and in April, Candida spp. remained prevalent, followed by Penicillium spp. at 26%, Fusarium spp. at 24%, and Aspergillus flavus, which appeared in samples collected from the Kharazi Valley.
