How to Become an Environmental Health Specialist in 2025
What Does an Environmental Health Specialist Do?
Environmental Health Specialists work to protect people and the environment from health hazards. Their daily tasks are varied, often involving inspections, investigations, and education. They are public health protectors working to make sure our air, water, and food are safe. They play a critical role in preventing disease and promoting wellness within communities. This can involve tasks like inspecting restaurants to ensure food safety standards are followed, or investigating sources of pollution that might contaminate local water supplies.
The appeal of this career stems from the direct impact you can have on people's lives. By identifying and mitigating environmental hazards, Environmental Health Specialists contribute to healthier communities and a more sustainable planet. You're helping to prevent outbreaks of foodborne illness, reduce exposure to harmful chemicals, and improve overall environmental quality. If you care about public health and the environment, this career offers a rewarding opportunity to make a real difference.
To further define this role, it's helpful to consider a few key definitions. "Environmental health" itself refers to the branch of public health that focuses on the relationships between people and their environment; it promotes human health and well-being and fosters healthy and safe communities. A "hazard" is anything that can cause harm, such as a chemical, a physical agent, or a biological organism. The goal of an Environmental Health Specialist is to identify these hazards and implement strategies to control or eliminate them. You can learn more about environmental health from organizations like the National Environmental Health Association (https://www.neha.org/).
Environmental Health Specialist Educational & Certification Requirements
Becoming an Environmental Health Specialist typically requires a bachelor's degree from an accredited institution. A degree program in environmental health science, environmental science, public health, biology, or a related field is standard. Coursework usually includes subjects such as toxicology, epidemiology, environmental law, water and air quality, waste management, and food safety. A strong foundation in science is key for this career path.
Beyond the degree, many positions require or prefer certification as a Registered Environmental Health Specialist/Registered Sanitarian (REHS/RS). This certification shows a standard of knowledge and competence to employers and the public. The specific requirements for REHS/RS certification vary by state, but usually involve passing an exam administered by the state's environmental health agency or by the National Environmental Health Association (NEHA). Visit NEHA's home page for more information.
In addition to passing an exam, candidates for REHS/RS certification often need to complete a certain amount of practical, supervised experience in the field. This experience helps solidify academic knowledge and gives the candidate real-world skills. Internships or entry-level positions at local health departments, environmental consulting firms, or governmental agencies are common ways to fulfill this requirement. Continuing education courses or workshops are often necessary to maintain certification.
