Question 3

Why is Legionella a particular concern in spa and hot tub operations?

Accepted Answer

Spas create ideal conditions: warm water, aerosolization from jets, and potential for biofilm

Answer

Spas are a primary source of Legionella outbreaks because warm water temperature, jet aerosolization, and complex plumbing create perfect growth conditions.

Question 4

How often should a public spa be completely drained, cleaned, and refilled?

Accepted Answer

Weekly or when TDS exceeds recommended levels
