The environment, particularly the water, has been damaged by the increased use of pesticides brought on by population development and the demand for agricultural products. Finding pesticide residues in agricultural water sources in Barzok, Kashan, in 2011 was the objective of this experiment. Materials and Techniques A cross-sectional, descriptive study that was conducted in the spring was one of the two studies. A total of 135 samples from different places in Barzok's agricultural water resources were mixed together at random. After sample extraction and processing, this was discovered utilizing HPTLC (High Performance Thin Layer Chromatography) equipment and CATS4 software. Finally, statistical ANOVA analysis was employed to review the collected data. The The results of the investigation showed that the highest levels of diazinon and chlorpyrifos, respectively, were 22.43 and 11.79 ppm, and that pesticide residues gradually reduced with time (p 0.001). In addition, after a month, 95.9% of chlorpyrifos and 88.8% of diazinon are eliminated. As a result, more diazinon and chlorpyrifos remained after a month of spraying than the predetermined, low requirement. It is suggested that unnecessary interaction with the region's water resources halt at least one month after spraying because chlorpyrifos degrades more quickly than diazinon. This is in addition to educating farmers on the safe use of pesticides..
