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.
