Relatively new research has been aimed at the impacts of wildfires on the quality of drinking water and on water-dependent natural resources. Wildfires are devastating and can lead to long-term changes to the landscape. With a significant amount of our Nation's drinking water sources originating in forested watersheds, evaluating the effect fires have on water quality is incredibly important. The USGS works with other federal and state land managers to assess water-quality after wildfires in order to help protect one of our most valuable resources. This web page provides an overview of USGS's research about domestic water use. It includes related research, publications, and news (Introduction).
