Registered Environmental Health Specialists (REHS) work to reduce the incidence of illness or injury for the people who live, work and play in our communities. Principle responsibilities include enforcing various regulations and codes that impact the protection of both public health and our environment. A degree in science and an eligibility letter from the California Department of Public Health are needed to begin this rewarding career path. 

REHS’s are employed throughout California and work both the public and private sectors. One of the primary attractions of this field is the wide range of program areas included, such as: food protection; housing; institutional environmental health; land use; community noise control; recreational swimming areas and waters; electromagnetic radiation control; solid, liquid, and hazardous materials management; underground storage tank control; onsite septic systems; vector control; drinking water quality; water sanitation; emergency preparedness; and milk and dairy sanitation.
