CMAQ Webinars

Webinars by CMAQ team members provide in depth information on different aspects of the modeling system.

TENORM: Rare Earths Mining Wastes

Rare earths are a group of elements that have electrical properties that make them useful in modern electronics, such as cell phones and magnets.

Air Quality Design Values

This is where EPA publishes the annual design values updates for the criteria pollutants.

TENORM: Copper Mining and Production Wastes

This page provides information about TENORM and copper mining and smelting.

Wildland Fire Research: Water & Ecosystems

Research is critical to better understand how fires affect water quality and supply and the overall health of an ecosystem. This information can be used to protect the safety of drinking water and assess the vulnerability of water supplies.

Wildland Fire Research: Human Health

Wildfire smoke is associated with a range of health effects, from less serious such as coughing and runny nose, to more serious such as respiratory and cardiovascular disease exacerbation, and even premature death.

Wildland Fire Research: Smoke Measurement

During wildland fire smoke events, people rely on timely public health warnings to help them take appropriate actions. Those warnings rely on accurate and real-time air pollution measurements.

Wildland Fire Research: What’s in Smoke?

EPA research on the effects of wildland fire smoke on air quality, the effects of wildland fire on water quality and ecosystems, the effect of smoke on public health, and actions that can be taken to reduce exposures to smoke.

Wildland Fire Research to Protect Health and the Environment

EPA is using its expertise in air quality research to fill the gaps in scientific information and to develop tools to prevent and reduce the impact of wildfires and controlled or prescribed burns.

Wildland Fire Research: Reducing Exposures

As wildfire smoke continues to impact the health of people across the United States, state agencies and community leaders want to know how best to educate and prepare residents on ways to reduce their smoke exposure and protect their health.

Winners of the Wildland Fire Sensors Challenge Develop Air Monitoring System Prototypes

The winners of the Wildland Fire Sensors Challenge developed air sensor monitoring systems for detecting pollutants from wildland fire smoke using emerging next generation monitoring technologies..

Land and Waste Management Research

EPA is working to develop methods and guidance to manage and clean up contaminated land, groundwater and nutrient pollution as well as develop innovative approaches to managing materials and waste including energy recovery.

Air Research

EPA's air research provides the critical science to develop and implement outdoor air regulations under the Clean Air Act and puts new tools and information in the hands of air quality managers and regulators to protect the air we breathe.
