Environmental Health Division

Environmental Health is the prevention, preservation, and improvement of environmental factors affecting the health and safety of our community. 

The Napa County Division of Environmental Health (DEH) enhances the quality of life of both residents and visitors by protecting public health and safeguarding environmental quality, educating the public to increase environmental awareness, and implementing and enforcing local, state, and federal environmental laws. 

The State of California mandates that only qualified, trained professionals may perform the duties within the scope of this field. Our staff of professionals have backgrounds in the sciences including chemistry, physics, biology, microbiology, mathematics and environmental health.
