Natural Resources Police Boat

Protecting the health and safety of Delaware residents and visitors is a primary goal of the Department of Natural Resources and Environmental Control (DNREC).

The Department works to protect the public from accidental releases of contaminants, from the affects of long-term pollution and from potential hazardous practices by industrial and other actors. DNREC monitors air and water quality, mosquitoes, and the potential for disease vectors to threaten the health of the public. And DNREC works to ensure that we can get out into Delaware’s natural areas and hunt, fish, hike, bike, swim and enjoy other outdoor recreation activities in safety.

Dealing with Hazards

DNREC helps communities and industry work to avoid problems with hazardous substances through efforts such as those led by the Emergency Response and Strategic Services Section, which oversees the Accidental Release Prevention Program and community-level emergency planning efforts. Emergency response teams are ready to respond to any accidents and coordinate with other state and local emergency response groups through the State Emergency Response Commission. And when it’s time to clean things up, the Remediation Section leads efforts re rehabilitate contaminated areas. Other related links:

Protecting Public Health

DNREC works with the Division of Public Health and others to protect the public from health threats that include mosquito-borne diseases, infectious wastes, contaminants found in the fish that we eat, and more. DNREC monitors air quality at testing sites throughout the state and provides regular air quality forecasts. And the state monitors and reports on water quality at recreational areas.
