What is the main concern associated with low chlorine residuals in a water system?

Health risks from pathogens
Reduced taste quality
Physical appearance issues
Increased water hardness

The correct answer is: Health risks from pathogens

The main concern associated with low chlorine residuals in a water system is health risks from pathogens. Chlorine is widely used as a disinfectant in drinking water systems to kill bacteria, viruses, and other microorganisms that can cause serious illnesses. When the chlorine levels drop too low, there is an increased risk that harmful pathogens may survive in the water supply, potentially leading to waterborne diseases. Maintaining a proper chlorine residual is essential for ensuring that the water remains safe for consumption. Water utilities monitor chlorine levels closely to prevent any health risks to the public. While factors like taste quality, physical appearance, and water hardness are important in water quality management, the primary focus when it comes to chlorine residuals is guaranteeing the safety of the drinking water by effectively controlling pathogens. This is crucial for public health and safety standards in water treatment practices.
