What is the recommended chlorine concentration for disinfecting a well or well pump?

The recommended chlorine concentration for disinfecting a well or well pump is 50 mg/l. This concentration effectively achieves disinfection by inactivating harmful microorganisms typically found in water sources. Chlorine is a potent disinfectant that, at this level, ensures a thorough treatment of the water system, promoting safety and compliance with public health standards.

Using 50 mg/l strikes a balance between effectively killing pathogens and minimizing potential adverse effects on water taste and odor. It is crucial to follow the guidelines set by authoritative organizations, such as the American Water Works Association (AWWA), for effective disinfection procedures. Higher concentrations could lead to issues such as unpleasant taste, odor, or potential corrosiveness to the system, while lower concentrations might not provide sufficient disinfection. This makes 50 mg/l the optimal choice for well disinfection.
