Quantifying The Extent Of Wildfire Impacted Streams In The Western United States, Grady Ball
Water Resources Professional Project Reports
Beginning in the mid-1980s, the number of fires and acres burned by wildfire in the United States has grown at an explosive rate. Several factors, anthropogenic and natural, have converged to create a new era of high frequency, high intensity fires, which is predicted to continue until at least mid-century. Investigations into wildfire impacts have largely focused on post-fire impacts on terrestrial systems, while effects on aquatic ecosystems have been underrepresented. The growing threat of fire to streams has accelerated the need for germane information regarding the spatial extent of fire impacts on watersheds and post-fire impacts to aquatic systems. …

Water quality has become an increasing concern in recent years. The environmental challenges surrounding water quality include the presence of dissolved metals and their potential impact on human health and the environment. The challenge is exacerbated because many important metals have multiple oxidation states, which affect the health and environmental behavior of the metal. Many metals are known carcinogens and increased anthropogenic effects have inexorably made metals’ accumulation an imposing threat. Analytical instrumentation has advanced in many areas, making it now possible to measure very low concentrations of multiple elements in water. Current interest is determining the chemical speciation of …
