Environmental Health Services strive to prevent injury and illness and promote health. This is done through education and enforcement of state and local laws. The Washington Ozaukee Public Health Department licenses and regulates retail food, hotels/motels, bed & breakfasts, public swimming pools, campgrounds, and body art establishments. Environmental Health Specialists are also responsible for sampling and inspecting small public drinking water systems, swimming beach monitoring, and providing radon information and test kits for residents.
