What does RWI stand for in pool management?

Recreational Water Illness, or RWI, refers to a range of illnesses that can be spread by water in swimming pools and other recreational water venues. These illnesses can be caused by pathogens found in the water, such as bacteria, viruses, and parasites, which can lead to infections or diseases. Understanding RWIs is essential for pool management as it helps operators implement safety and sanitation measures to minimize the risk of outbreaks and ensure the health of pool users. This involves regular water testing, maintaining proper chemical balance, and adhering to hygiene practices, all aimed at creating a safe recreational environment.
