Water crisis is a huge problem in the world and many people cannot get clean water. In many countries, people use untreated wastewater for farming. This is a big problem for the environment and people's health worldwide. Instead of using dirty water that hasn't been cleaned, using water that has been cleaned is a better and more eco-friendly choice. The findings indicate that we can make significant progress in using wastewater for farming with the improvements in treatment techniques that we already have (Kesari et al, 2021). But, to make sure that wastewater irrigation is safe and can continue in the long term, we need to check the quality of the water and inspect the soil, crops, and irrigation systems (Yerli and SAHİN, 2022). The findings revealed that over a long period of time, soils watered with wastewater contain a high amount of heavy metals compared to fields watered with fresh water. The amount of heavy metals in the soil was much higher in clay soils that were watered with wastewater compared to sandy soils that were also watered with the same wastewater (Alnaimy et al, 2021). Soil can act as a sustainable solution and natural filter for wastewater treatment. The structure of the soil and its ingredients are very effective for this purpose. To increase the efficiency of this treatment, the soil structure can be modified by adding materials such as woodchips (Martínez-Hernández et al, 2020). The results show that zeolite in permeable layers of soil is more useful for reducing pollutants than gravel. Also, the use of steel waste slag can increase the soil's ability to remove phosphorus and nitrogen from wastewater (Chen, 2021). Soil-based wetlands for the release of treated wastewater have gotten to be a prevalent strategy to diminish stream to surface waters as well as give extra treatment that can be exceptionally advantageous in evacuating phosphorus from wastewater (Morvannou et al, 2022). Studies have shown that harmful substances like bacteria and chemicals in wastewater decrease when they go through soil. The earth can get better on its own over time, which helps to lower the amount of pollution (Behrooz, 2005). When tiny organisms in a place are allowed to grow and the temperature goes up, especially above 13 degrees, it can also speed up the process of getting rid of harmful substances. It's important to understand that soil can continue to remove substances like phosphorus from wastewater for a long time (Doosky et al., 2013; Yuan et al., 2013; Eveborn et al., 2012). Using dirt to clean dirty city water helps make more air in the water and reduces the dirty air in the water. It also helps to get rid of things floating in the water, make the water less cloudy, and make less harmful bacteria. This wastewater treatment process is different because it doesn't use air chemicals or mechanical energy, and it doesn't need a lot of space (Kadam et al., 2009). Soil can help clean dirty water by removing some of the dirt in it. (Teerlink et al., 2012). Soil-based systems are becoming more important in places without centralized wastewater systems. These systems treat and remove wastewater. Research has shown that soil can naturally filter out certain things like COD, SS (Suspended Solids), phosphorus, and nitrogen. Natural soils can help to clean wastewater fast (Baykuş et al, 2022). A special type of soil called multilayer soil can effectively clean dirty water. It is also good at taking care of nature. It can take away almost all of the dirt and waste from the water, as well as most of the nutrients. This special soil technology helps pollutants move from the top layers of the ground to the exit. It stays in touch with the surroundings and helps to get rid of pollutants using different ways. Rewrite this passage in simpler language (Sbahi et al, 2022). Sunlight can affect the quality of wastewater. In simple terms, using sunlight to clean dirty water can ensure that crops, like lettuce, which are watered with this clean water, are safe from harmful E-coli bacteria (Bichai et al., 2012). Sunlight and warmer weather are the main causes of coliforms dying (Yukselen et al., 2002). Coliform are very small living things that can be found in water and can cause sickness. The bacteria called coli struggle to survive and grow in very hot temperatures. Additionally, if there isn't enough food or if the temperature rises above 37 degrees Celsius, they won't be able to survive in the water and might turn into solid form (Sakyi, 2012 and Asare; Ghasemi, 1988). When there is more sunlight and the disinfection process lasts longer, and the radiation is stronger, it does a better job of killing harmful microorganisms like coliform bacteria. This means that when the sun is out for longer periods, there is more time for sunlight to clean and make the water safer to use (Doosti et al. 2011). When the water is very dirty, it can make it easier for harmful organisms to grow and spread, and it becomes more difficult to clean the water (Dobaradaran et al., 2006; Dezuane, 1997). Other factors that can make dirty water less bad include weakening it and moving it around. For example, when poop goes into the river and goes with the current, the water's dirtiness will be different in different places and at different times (Ji, 2008). Pollutants in unusual or non-traditional sources of water are a major issue, especially when it comes to using wastewater and water that runs off from land for farming. We must deal with this problem because we are having a shortage of water (Hasan Akhli, 2006). However, when water used for irrigation enters surface water, it can make the water quality worse and cause more algae and weeds to grow. This can also make the water harmful and unclean. So, the oxygen in the water goes down. At the same time, soil that erodes easily is being added. Please simplify this text to make it easy to understand (Fred Lee et al., 2007). Studying the cleanliness of runoff water when using wastewater for irrigation is important because it helps us figure out how to either dispose of it properly or reuse it. This research is one of the first to explore how soil movement influences the quality of wastewater. Most studies have looked at how wastewater goes into the ground and how that affects the treatment of the wastewater. It is important to mention that there hasn't been a lot of research on this subject using Persian and Latin sources.
