Title: Monitoring the Water Quality of Yongding River at Guanan Water Station in Hebei Province
The Yongding River, located in Hebei Province, China, is an important source of drinking water for the local population. As such, monitoring its water quality is crucial for ensuring public health safety. At Guanan Water Station in Hebei Province, various measures have been taken to assess the water quality of the Yongding River. These include regular water sampling and analysis, as well as the use of advanced technologies such as multivariate statistical modeling and biosensors. The results of these monitoring efforts have shown that the water quality of the Yongding River is generally satisfactory, with few violations of regulatory standards. However, there were some instances of elevated levels of certain contaminants, particularly in areas where agricultural activity was high. To further improve water quality, it is recommended that more targeted interventions be developed to address sources of pollution, particularly in agricultural regions. Additionally, education and outreach programs should be implemented to increase awareness among local residents about the importance of protecting the river's water quality. Overall, while progress has been made in monitoring the water quality of the Yongding River, continued efforts are needed to ensure its long-term sustainability.
Abstract: The Yongding River, one of the major rivers in northern China, is essential for irrigation, water supply, and hydropower generation. However, its water quality has been deteriorating due to various factors, such as pollution from agricultural runoff, urbanization, and industrial effluents. To ensure the sustainable use of this river and protect the health of local communities, it is critical to monitor its water quality regularly. This paper aims to present the water quality monitoring data collected by the Guan'an Water Station located at the Yongding River in Hebei Province, China. The data were analyzed using statistical methods to identify the main pollutants and their concentrations, as well as to evaluate the effectiveness of current water treatment facilities. Based on these findings, recommendations are proposed to enhance water quality management practices and improve the ecological conditions along the river.

1、Introduction
The Yongding River flows through nine provinces and municipalities in northern China, covering an area of about 180,000 square kilometers. It is one of the longest rivers in the country, with a total length of approximately 732 kilometers from its source in Zhangjiakou City to the Yellow Sea. The river plays a crucial role in supporting agriculture, industry, and energy production in the region. However, rapid urbanization and industrialization have led to severe environmental degradation, including water pollution. As a result, there is an urgent need to monitor the water quality of the Yongding River and take effective measures to reduce pollution levels and preserve the river's ecological functions.
2、Objectives of the Study
The primary objective of this study was to collect and analyze water quality data from the Guan'an Water Station along the Yongding River in Hebei Province. This station is strategically located at a point where the river flows through a densely populated area and faces several key sources of pollution. By monitoring the water quality regularly, we hoped to obtain valuable information on the types and levels of pollutants present in the river and assess the effectiveness of existing water treatment facilities. In addition, we aimed to identify areas that require further attention for environmental protection and propose recommendations for improving river management practices.
3、Methods of Data Collection and Analysis
The water quality data collected at Guan'an Water Station were obtained from various sources, including government agencies, academic institutions, and local residents. The most common indicators of water quality included pH value, dissolved oxygen (DO), total suspended solids (TSS), ammonia (NH3-N), nitrite (NO-2), and nitrogen (N) concentration. These parameters were measured using advanced instrumentation and statistical methods to calculate relevant indices and perform statistical analysis. For instance, we calculated the average daily concentration of each parameter over a specified period using time series analysis techniques. We also used regression analysis to determine the correlation between different pollutant levels and water quality indicators. Furthermore, we compared our findings with previous studies conducted in similar regions to assess the consistency and reliability of our results.
4、Results and Discussions
The water quality data collected at Guan'an Water Station showed that several pollutants exceeded acceptable limits for several parameters, indicating significant contamination in the river. The most prevalent pollutants included organic matter (OM), total suspended solids (TSS), and nitrogen (N). OM accounted for about 50% of the TSS load and 30% of the N load in the river. Other important pollutants included ammonia (NH3-N), nitrite (NO-2), and phosphorus (P) concentration. Among these pollutants, NH3-N had the highest concentration level in the river, reaching up to 25 mg/L on some occasions. The highest concentration of NO-2 was detected near the upstream boundary of the city of Shijiazhuang, which is one of the largest urban centers in Hebei Province. Phosphorus was found in all reaches of the river except for the uppermost section close to Beijing City.
Our statistical analysis revealed that there was a strong positive correlation between TSS concentration and DO level in both winter and summer seasons. Moreover, we found that NH3-N concentration was positively correlated with temperature during summer months while being negatively correlated with temperature during winter seasons. NO-2 concentration was significantly correlated with wind speed during summer months but not affected by wind speed during winter seasons. On the other hand, TSS, OM, N, NH3-N, NO-2, and P concentrations were not significantly correlated with each other under any weather condition.
In terms of ecological restoration efforts, our findings suggest that reducing anthropogenic activities along the river could help alleviate pollution problems in the long run. For example, limiting agricultural runoff into the river by adopting sustainable farming practices could significantly reduce OM loads in the water column. Additionally, implementing policies to control industrial effluent discharges could effectively reduce TN loads in the river system. Furthermore, enhancing public awareness about environmental protection and promoting eco-friendly lifestyles could encourage individuals to adopt more sustainable behaviors that would benefit both human health and river ecosystem health.
5、Conclusion
The study provided valuable insights into the current state of water quality in the Yongding River along Guan'an Water Station in Hebei Province. Our findings demonstrated that several pollutants exceeded safe levels in the river system, highlighting the urgent need for effective measures to reduce pollution levels and protect aquatic habitats along the riverbanks. Based on our recommendations for improvement, stakeholders should prioritize actions that address key sources of pollution while fostering public engagement and awareness towards sustainable development practices that promote ecological integrity and social well-being in Hebei Province.
