Recognizing public health, the environment, and the economy as key components in finding solutions to air pollution, DNREC has made significant progress in adopting effective and publicly-acceptable plans for emissions reductions at the lowest costs to the regulated community.
Provides air quality data from monitoring stations throughout the state. Data available include ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, particulate matter, temperature, wind direction, humidity and wind speed.
Ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, particulate matter less than 10 microns, particulate matter less than 2.5 microns, and lead are considered criteria pollutants because of their impact on human health and welfare.
DNREC is always looking for better ways to provide citizens with the most accurate and timely air quality data. This moveable monitoring platform can collect data in areas without permanent monitoring stations.
Contains information about toxic chemicals in Delaware. It is based on annual reports from facilities that use or manufacture those chemicals. DNREC publishes annual state Toxics Release Inventory (TRI) reports and the Environmental Protection Agency (EPA) publishes national TRI reports. Annual reports are published at the end of each calendar year and cover the previous calendar year.
