Just got this from the a representative of the National Academy of Sciences who asked me to post here.
Scope of work: An ad hoc committee of The National Academies will review the state of science with respect to Legionella contamination of water systems and issue a report that addresses the following: ecology and diagnosis; transmission via water systems; review of outbreak and environmental data; prevention and control; policy and training issues; as well as the gaps in science and how to address them. Partial funding has been secured through the Alfred P. Sloan Foundation. Additional funding is still sought before the study will officially begin. A draft statement of task is available upon request. Please contact Dr. Laura Ehlers (LEhlers@nas.edu) for more information about the study.
