Environmental Health Science and Practice
The environment—the air we breathe, the water we drink, the food we eat—plays a vital role in our health and wellbeing.
CDC’s Division of Environmental Health Science and Practice (DEHSP) works to protect the health and quality of life of all people in the United States. We look at how the environment affects our health through environmental epidemiology, collect and share environmental health data, and provide support to state and local environmental health practitioners. We also plan for and respond to natural, chemical, and radiation disasters. We are especially committed to protecting the health of those most vulnerable to certain environmental hazards—children, the elderly, and people with chronic health conditions.
