Abstract

Background and purpose: TOC is one of the substances that, if it increases in drinking water, indicates the possibility of contamination of water with sewage or other contaminated waters. TOC represents the total organic carbon or indicator for the amount of organic matter present in the water. In many countries, TOC is used to compare the results of raw water sources and water purification systems. Also, the accumulation of pollutants in soil, which acts as a living substrate for humans and other organisms, is a function of soil organic matter content. Methods: In this research, 96 samples for analysis of TOC were obtained from 96 point of water supply sources in autumn, winter and spring in 1394-95 according to the method recommended in the standard method. The levels of TOC and DOC were measured by using ANATOC analyzer. The heat loss method was also used to measure total organic carbon in soil samples. Data were analyzed using SPSS software and using Kolmogorov-Smirnov and Shapiro-Wilk tests. Results: According to the tests, the average concentration of TOC in water supply sources was 0.76 mg/l, the average concentration of TOC in soil was 0.45 percent and the average DOC was 6.82 mg/l. Kruskal Wallis test was used to analyze the effect of land usage on TOC concentration in water specimens and DOC concentration in soil samples and one-way variance test to compare soil TOC concentration in different land uses Conclusion: The average TOC content in water supplies is lower than the recommended and recommended limits, so the low level of TOC in water resources can be as a result of the performance of the layers of soil to filter organic substances and prevent the introduction of these compounds into water resources. On the other hand, concentrations of TOC in water specimens and DOC concentration in soil samples are not different in different land uses. Therefore, it can be concluded that the type of land use has no significant effect on the concentration of water TOC and soil DOC.
