AIHA Guidelines for Recognition, Evaluation and Control of Legionella in Building Water Systems

The American Industrial Hygiene Association (AIHA) published a guideline for the “Recognition, Evaluation, and Control of Legionella Hazards in Building Water Systems” in June 2015. This guidance updates and expands upon information previously used to conduct environmental source assessments for Legionella during outbreak investigations. It also provides a framework for competent professionals to establish a proactive assessment strategy of hazard assessment and longitudinal monitoring of building water systems. The intent is that they use it to develop evaluation and assessment strategies for Legionella and shift to a proactive approach that may reduce the impact this disease has on public health.
