     ## Introduction
-    Over the last five decades, the land area burnt by forest fires in the western United States has increased tenfold. This trend is expected to continue and even accelerate under the influence of climate change. Given this scenario, the societal impacts of wildfires are of interest. While the impact of wildfires on the loss of human life, property, and air pollution is obvious, less understood are secondary environmental impacts that affect regions remote from the location of the fires. Recent studies show that smoke from wildfires is expected to become the major air pollutant in the United States. However, the potential impact of wildfires on water quality, especially mercury contamination, is not well studied.

     ## Wildfires Lead to Deposition
-    As organic matter is consumed during wildfires, nutrients (phosphorus, nitrogen, carbon) and a variety of heavy metals such as mercury, arsenic, and lead is released into soil and air . Following wildfires, subsurface infiltration of water often is reduced due to the removal of surface leaf litter and organic matter from the topsoil layer. This leads to an increase in surface runoff. Further, the removal of leaf litter exposes the soil layer to the direct impacts of rainfall, which coupled with the loss of vegetation root structure to keep soil in place, leads to a higher potential for soil erosion after the occurrence of wildfires. A combination of these factors can lead to higher nutrient and heavy metal inputs into nearby water bodies.

     Similarly, nutrients and heavy metals transported in smoke plumes can also affect remotely-located water bodies. Wet removal or the washout of particulate and soluble gasses by rainfall can deposit nutrients and heavy metals onto soil and water surfaces. Particulate and gaseous emissions from fires can also reach soil and water surfaces through dry deposition, which is their removal from the atmosphere through the action of gravitational settling and diffusion. 
 
-    Pollution of water bodies by nutrients removed from the atmosphere by wet and dry deposition can have significant consequences. The input of phosphorus and nitrogen into water bodies can fertilize and stimulate algal growth. Increase in water turbidity can  block sunlight needed by aquatic plants and harm their growth. The overabundance of algae can deplete dissolved oxygen leading to the death of aquatic animals. Fertilization can also lead to harmful algal blooms, which release toxins and cause death of animals.

     ## Conclusion
     A major implication of this discovery is that waterbodies in the western U.S. could be subject to increased mercury pollution if the increasing trend of exposure to wildland fire smoke plumes continues to occur. High average values of AOD associated with the smoke plumes from the fires in recent years are reflective of increases in fire intensity and smoke emissions.
