![]() In the aftermath of a large wildfire, rainstorms flush vast quantities of ash, sediment, nutrients and contaminants into streams, rivers, and downstream reservoirs. Vegetation that holds soil in place and retains water is burned away. Water supplies can be adversely affected during the active burning of a wildfire and for years afterwards. During active burning, ash and contaminants associated with ash settle on streams, lakes and water reservoirs. Just as wildfires impact air quality, they can also affect the quantity and quality of water available. More recently, EPA researchers have begun to look at a less understood area of research-the impact of these fires on our water supply, the natural resource we depend on for drinking, irrigation, fishing and recreation. EPA has been exploring the impacts of both short-term and long-term exposure to wildfire smoke on human health. The fires have taken a toll in human life, but also in the health of those exposed to the smoke. ![]() These wildfires destroy trees, vegetation, wildlife, and infrastructure.
