Water quality in drinking-water reservoirs is crucial for ensuring safe and healthy water supplies. However, these reservoirs are vulnerable to various factors that can negatively impact water quality. This article presents a comprehensive study focused on identifying and assessing the key impact factors affecting water quality in drinking-water reservoirs. The study employs a rigorous methodology involving data collection, laboratory analysis, and advanced monitoring techniques. Natural and anthropogenic factors such as sedimentation, nutrient loading, microbial contamination, chemical pollutants, temperature fluctuations, and land-use practices are examined in detail for their potential impacts on water quality. Assessment methodologies, including statistical analysis and modeling techniques, are utilized to quantify the significance of each factor and its contribution to water quality degradation. Case studies are presented to illustrate the practical application of the study's findings. Management and mitigation strategies, such as source protection, watershed management, and treatment technologies, are discussed to safeguard water quality. The research outcomes emphasize the need for a holistic approach to water quality management, integrating scientific research, advanced monitoring, and effective governance.

Water is an essential resource for sustaining life, and the quality of drinking water is of paramount importance for public health. Drinking-water reservoirs serve as crucial sources of freshwater supply, but they are susceptible to various factors that can affect water quality. Understanding and identifying these impact factors is vital for the effective management and protection of drinking-water reservoirs. This article presents a comprehensive study that focuses on identifying and assessing the key water quality impact factors in drinking-water reservoirs.
Numerous analytical methods have been developed and employed in previous studies to evaluate the factors impacting water quality, such as multivariate analysis, artificial neural networks (ANNs), support vector machines (SVMs), and genetic algorithms (GAs). The relationships between reservoir water quality and impacting factors are generally non-parametric and involve complex interactions. Therefore, favorable model fits are difficult to obtain using traditional statistical methods [12]. Methods using ANNs, SVMs, and GAs may not provide easily understandable explanations for researchers to obtain a complete understanding of the underlying nature of the data. In comparison, decision tree analysis has no distinctive data requirements. It can identify the most decisive variables and offer easily understandable statements. Decision tree analysis has been widely used in various fields, such as ecological modeling, decision making, diagnosis, and marketing operations. However, it has seldom been applied to water quality studies. In this study, decision tree analysis was employed to classify the water quality levels of reservoirs.

It explores both natural and anthropogenic factors, including sedimentation, nutrient loading, microbial contamination, chemical pollutants, temperature fluctuations, and land-use practices. Each factor is discussed in detail, highlighting its potential impacts on water quality.
Assessment of Water Quality Impact Factors
This section focuses on the assessment methodologies employed to evaluate the impact factors identified in the previous section. It discusses the use of statistical analysis, modeling techniques, and data interpretation to quantify the significance of each factor and its contribution to water quality degradation.
Case Studies

These case studies highlight specific drinking-water reservoirs and their unique challenges, demonstrating how the study's findings can be implemented to address water quality issues effectively.
Management and Mitigation Strategies
In this section, the article discusses management and mitigation strategies to safeguard water quality in drinking-water reservoirs. It explores preventive measures such as source protection, watershed management, and best management practices. It also examines treatment technologies, monitoring systems, and policy frameworks aimed at maintaining and improving water quality.
Human activities produce residential pollutants, primarily food waste, washing residues, hospital sewage, and household garbage. Zhejiang Province is densely populated, and the high population density in reservoir catchments has always been a primary challenge in reservoir water protection. Domestic pollutants with abundant nitrogen and phosphorus and nutrients have increased considerably in recent years with the rapid improvement of people’s living standards. However, due to the lack of proper processing of these pollutants, most were directly discharged into the natural environment and carried by runoff into water bodies. Moreover, the reservoir areas are rich in tourist resources. The dramatic expansion of the catering industry and tourism has led to an increase in the fluid population and thus in pollution.
Thus, it is necessary and urgent to enhance the control of domestic pollutants for reservoir water source maintenance. Construction of sewage treatment facilities is recommended to negate the harmful effects associated with expanding population. Harmless disposal of residential garbage could be an effective way for reservoir water protection. Landfills within watersheds must be strictly prohibited to prevent adverse impact of pollutants on reservoirs. In addition, reductions in population densities within watersheds could be a promising approach to alleviate the pressure on water quality derived from human activities.
Future Directions
The article concludes by highlighting potential areas for future research, such as emerging contaminants, climate change impacts, and the integration of new technologies for real-time monitoring and early detection of water quality issues.
By conducting a comprehensive study on identifying and assessing water quality impact factors in drinking-water reservoirs, this research provides valuable insights and guidance for policymakers, water resource managers, and researchers working towards the preservation of clean and safe drinking water supplies. Implementing the findings of this study will contribute to the sustainable management of drinking-water reservoirs and the protection of public health.
The conclusion summarizes the key findings of the comprehensive study on identifying and assessing water quality impact factors in drinking-water reservoirs. It underscores the importance of a holistic approach to water quality management, combining scientific research, advanced monitoring techniques, and effective governance to ensure the availability of safe drinking water for communities.
