How frequently should water treatment facilities monitor chlorine residual levels?

• A. Weekly
• B. Monthly
• C. Daily
• D. Yearly

Answer: (C)

Monitoring chlorine residual levels in water treatment facilities is essential for ensuring safe and effective disinfection. Chlorine is widely used to kill pathogenic microorganisms and to maintain a residual concentration that helps prevent contamination in the distribution system. Chlorine residual levels should be measured daily to ensure they are within the required operational range. This frequency is vital because chlorine levels can fluctuate due to various factors, including changes in water demand, the presence of organic materials, and fluctuations in water temperature. Daily monitoring helps operators quickly identify and rectify any issues that could lead to insufficient disinfection or potential health risks. By adhering to daily monitoring practices, water treatment facilities can ensure that they consistently provide safe drinking water to the community while also complying with regulatory standards that mandate certain levels of chlorine residual in the water supply. Regular and consistent monitoring helps in maintaining water quality and protecting public health.
