What is the action limit for bacteria in water?

The action limit for bacteria in water is set at 20 colony-forming units per milliliter (cfu/ml). This threshold is based on regulatory standards that are designed to ensure the safety and quality of water, particularly in healthcare settings where patients are vulnerable to infections. Maintaining bacterial counts below this limit is crucial for protecting patient safety, as higher levels can increase the risk of disease transmission.

The action limit serves as a guideline for monitoring water quality and determining the necessary interventions needed to reduce bacterial contamination. When bacterial levels exceed this limit, it typically triggers a response to investigate the source of contamination, implement corrective actions, and re-test the water to ensure compliance with health standards. This proactive approach helps mitigate potential health risks associated with exposure to contaminated water.
