Clear wells must be protected from what type of risks?

Clear wells, which are used in water distribution systems to store treated water before it enters the distribution system, must be protected from contamination and unauthorized entry. Contamination can occur through various means, such as the introduction of pathogens, chemicals, or other pollutants that can compromise the safety and quality of the water. Unauthorized entry poses a risk because it can allow individuals to deliberately or accidentally introduce contaminants into the clear well. Therefore, ensuring that clear wells are secure and protected against both contamination and unauthorized access is crucial for maintaining the integrity of the water supply and protecting public health. This involves implementing physical security measures, regular inspections, and adhering to water quality standards.
