Analysis Of Nitrate Levels (NO3) And Nitrite (NO2) In Water Samples Using Spectrophotometers In Perumda Tirtanadi Prov North Sumatra
Introduction
The availability of clean and safe drinking water is a fundamental human right, and its quality is crucial for maintaining public health. In recent years, the levels of nitrate (NO3) and nitrite (NO2) in water sources have become a significant concern due to their potential health risks. Nitrate and nitrite are common pollutants in water sources, and their presence can lead to various health problems, including blue baby syndrome, cancer, and neurological disorders. Therefore, it is essential to monitor and regulate the levels of these pollutants in water sources.
In this study, we aimed to determine the levels of nitrate and nitrite in raw water samples and consumption water using a spectrophotometer in Perumda Tirtanadi, North Sumatra Province. The study employed UV-VIS spectrophotometry, a widely used and effective method for determining the levels of nitrate and nitrite in water samples.
Research Methodology
The methodology applied in this study included sampling of water from different sources, both raw water from natural sources and water that has been processed for consumption. The use of UV-Vis spectrophotometer is a very effective method in determining the levels of nitrate and nitrite because of its high sensitivity and the ability to measure the concentration of substances in a solution with good accuracy.
In the analysis process, the water sample that has been taken will be processed and measured its absorbance using a spectrophotometer. By comparing the results of absorbance with the standard curve that has been made before, we can calculate the levels of nitrate and nitrite in each sample.
Sampling and Data Collection
The sampling process was conducted in two stages: raw water sampling and consumption water sampling. Raw water samples were collected from natural sources, including rivers, lakes, and springs, while consumption water samples were collected from the water treatment plant in Perumda Tirtanadi.
A total of 30 water samples were collected, including 15 raw water samples and 15 consumption water samples. The samples were then transported to the laboratory for analysis using UV-VIS spectrophotometry.
Results and Discussion
The analysis results show that the level of nitrate in raw water samples is in the range of 20 mg/l, while the nitrite level is measured 1 mg/l. This level is still within the safe threshold determined by the government. This shows that the quality of raw water in the region is still quite good and worth processing into safe water for consumption.
For consumption water samples, nitrate levels recorded 10 mg/l and nitrite 3 mg/l. These results also show that the water supplied to the community meets the standards set by the Ministry of Health. In other words, people who use water from Perumda Tirtanadi can feel safe because the water they consume has gone through a good processing.
Comparison with Government Standards
The results of this study were compared with the government standards set by the Government Regulation of the Republic of Indonesia No. 22 of 2021 concerning Water Quality Standards (Class I) and the Minister of Health Regulation of the Republic of Indonesia No. 2 of 2023.
The results show that the levels of nitrate and nitrite in raw water samples meet the quality standards stipulated in the Government Regulation of the Republic of Indonesia No. 22 of 2021, namely nitrate as much as 20 mg/l and nitrite as much as 1 mg/l. Meanwhile, consumption water samples also meet quality standards in accordance with the Minister of Health Regulation of the Republic of Indonesia No. 2 of 2023, which sets a maximum nitrate limit of 10 mg/l and nitrite a maximum of 3 mg/l.
Conclusion
From the analysis of nitrate and nitrite content, it can be concluded that the water produced by the Tirtanadi Perumda North Sumatra Province meets the water quality standards set by the government. This is very important to maintain public health and ensure that clean water needs can be met safely.
Further research and periodic monitoring are needed to continue to maintain water quality in accordance with applicable standards. Thus, we can prevent the possibility of pollution and guarantee the sustainability of water resources in the future.
Recommendations
Based on the results of this study, the following recommendations are made:
- Regular monitoring: Regular monitoring of water quality is necessary to ensure that the levels of nitrate and nitrite remain within the safe threshold.
- Improvement of water treatment: The water treatment plant in Perumda Tirtanadi should be improved to ensure that the water supplied to the community meets the standards set by the Ministry of Health.
- Public education: Public education is necessary to raise awareness about the importance of water quality and the potential health risks associated with high levels of nitrate and nitrite in water sources.
By implementing these recommendations, we can ensure that the water produced by the Tirtanadi Perumda North Sumatra Province remains safe and clean for consumption.
Q: What are nitrate and nitrite?
A: Nitrate (NO3) and nitrite (NO2) are common pollutants in water sources. Nitrate is a naturally occurring compound found in soil, rocks, and water, while nitrite is a byproduct of the breakdown of nitrate in the environment.
Q: Why are nitrate and nitrite a concern in water sources?
A: High levels of nitrate and nitrite in water sources can lead to various health problems, including blue baby syndrome, cancer, and neurological disorders. Nitrate and nitrite can also cause gastrointestinal problems, such as diarrhea and vomiting.
Q: What are the safe levels of nitrate and nitrite in water sources?
A: The safe levels of nitrate and nitrite in water sources vary depending on the country and region. In the United States, the Environmental Protection Agency (EPA) sets a maximum contaminant level (MCL) of 10 mg/L for nitrate and 1 mg/L for nitrite.
Q: How are nitrate and nitrite measured in water samples?
A: Nitrate and nitrite are typically measured in water samples using UV-VIS spectrophotometry, a widely used and effective method for determining the levels of these pollutants.
Q: What is the significance of the study on nitrate and nitrite in water samples?
A: The study on nitrate and nitrite in water samples is significant because it provides valuable information on the levels of these pollutants in water sources. This information can be used to develop effective strategies for reducing the levels of nitrate and nitrite in water sources and ensuring the safety of drinking water.
Q: What are the implications of the study on public health?
A: The study on nitrate and nitrite in water samples has significant implications for public health. The results of the study suggest that the levels of nitrate and nitrite in water sources are within the safe threshold, which is a positive finding for public health.
Q: What are the recommendations for reducing the levels of nitrate and nitrite in water sources?
A: The recommendations for reducing the levels of nitrate and nitrite in water sources include regular monitoring of water quality, improvement of water treatment, and public education on the importance of water quality.
Q: How can individuals protect themselves from the health risks associated with nitrate and nitrite in water sources?
A: Individuals can protect themselves from the health risks associated with nitrate and nitrite in water sources by using water filters or purification systems that can remove these pollutants, and by drinking bottled water or water from a trusted source.
Q: What is the role of government agencies in regulating the levels of nitrate and nitrite in water sources?
