Water hardness testing is still performed once per week if a facility does not have a softener. What is the frequency of this testing?

Water hardness testing is crucial for facilities, especially those involved in processes sensitive to water quality. Regular testing ensures that any variations in water hardness can be monitored and addressed promptly. In a facility without a water softener, which would typically help in managing and reducing calcium and magnesium concentrations, weekly testing becomes essential. This frequency allows for immediate corrective actions if the hardness level fluctuates, which can have downstream effects on equipment performance and overall water system efficiency. By testing weekly, staff can maintain optimal water conditions and ensure compliance with operational standards. This protocol is aligned with best practices in water management and is why the answer indicates that the testing is conducted weekly.
