Environmental health is the study of how our health is changed by things around us. The environment is everything you eat, touch and breathe every day. The Environmental Protection Agency (EPA) is an agency within the United States that works to protect human health and the environment. Although Northeast Nebraska Public Health Department does not have a formal environmental health program, we are able to provide Radon test kits, Water Testing kits, resources for the cleanup of environmental hazards and information for environmental hazard mitigation.
