Water pollution poses a threat to the environment and affects not only animals and livestock but also human health. Among these pollutants, non-toxic and organic solvents are the most important because they are toxic, persistent, and difficult to purify with existing methods. For this reason, many research groups are looking for ways to detect and treat contaminated water and wastewater. Based on the above, the situation is currently under review. The results showed that there are a variety of pollutants in water bodies in the United States that affect many people, and some have other ways to treat water pollution. It was decided that a successful challenge would be to develop regional sanitation measures based on the specific needs of the area of interest. Therefore, water treatment facilities should be designed according to the contaminants in the water in the region and treated according to the needs of the stakeholders. The impact on animal and plant life has attracted researchers and environmentalists. It is no less harmful than air and soil pollution, but it has a greater impact on them. This study focuses on the analysis of the concept of pollution and its effects on human health and sources of water pollution. The health effects of pesticides range from mild allergies, eye irritation, breathing difficulties, and reproductive abnormalities to deadly chronic diseases like cancer. This challenge to food safety may be addressed by preventive strategies that include the use of alternative sustainable agricultural practices or mitigating strategies that are based on reducing pesticide exposure from food and water by different processing techniques. This work provides a comprehensive occurrence of pesticides in drinking water of Uttar Pradesh (India) and their possible treatment. There are many methods of pollution besides soil pollution, the most important of which are biological pollution, physical pollution, and the disposal of materials and wastewater into rivers, lakes, and oceans.
