Investigation of Environmental Impacts associated with Nonpoint Source Pollution

Nonpoint source (NPS) pollution currently is responsible for most of   the water quality impairments in the United States. NPS pollution   occurs when rainfall, snowmelt, or irrigation runs over land or   through the ground and picks up pollutants such as nutrients, road   salt, and sediments. These pollutants are then deposited into   rivers, lakes, and coastal waters or introduced into ground water,   resulting in ecological impairments to aquatic ecosystems.  NPS   pollution is widespread and associated with numerous activities,   including agriculture, forestry, grazing, septic systems,   recreational boating, urban runoff, and construction. It is critical   that we understand how NPS pollution impacts aquatic ecosystems.    In this study, scientists at Grand Valley State University's Annis   Water Resources Institute are conducting an experimental   investigation that simulates NPS-contributing events in the lower   Muskegon River watershed. This project is aimed at better   understanding the impacts of NPS pollution on lower trophic levels,   which form the base of the food web that ultimately supports the   fisheries in this region. A unique aspect of this research is the   comparison of how the different trophic levels (i.e., bacteria,   algae, and macroinvertebrates) respond to NPS pollution among   different habitats (river, wetland, and lake) and during different   seasons. This multi-habitat approach will give us new insight on how   NPS pollution impacts different biological communities living in   different environments and how these impacts change seasonally.
