A health inspector, or Environmental Health Specialist is a public employee who investigates health hazars in a wide variety of locations, then will take action to mitigate or eliminate the hazards. Usually the public perception of a health inspector is someone who examines restaurants and ensures they maintain sanitary standards for food safety set by the regulating authority. However, most health inspectors have broader job duties, including inspecting swimming pools, substandard housing conditions, public schools, day cares, nursing homes, and personal service establishments such as tattoo parlours. Depending on their jurisdiction, Registered Environmental Health Specialists often permit and inspect wells, private water systems, or individual subsurface sewage disposal (septic) systems. Other tasks include, public swimming pool inspections, campground inspections and mobile home park inspection.
