Water samples from 52 whirlpools (jacuzzi), water temperature 35–40°C, and from 50 swimming pools, water temperature 8–30°C, were investigated for the presence of Legionella pneumophila. This was isolated from 11 of 28 whirlpools with free available chlorine less than 0.3 mg/1. No legionellas were detected in 23 whirlpools with free available chlorine over 0.3 mg/l. Legionella pneumophila was found in two swimming pools. The results indicate that 0.3 mg/l of free available chlorine is sufficient to eliminate legionellas from whirlpools.
