It is a common misconception that the expertise of the industrial hygienist (IH) on a water management team is solely to collect environmental data. The education, training and experience of the IH places him/her in a unique position to contribute to the design of the risk assessment process and sampling plans, and assist in the identification, implementation, and evaluation of control measures. The presenter will provide a review of considerations for all phases of the risk assessment process including design, implementation, interpretation, and control. “Lessons learned” will be presented using examples from water risk assessments in actual healthcare settings.
