Nitrogen Storm Drain Filter: My poster is addressing the Nitrogen entering the Chesapeake Bay. As forests and wetlands have been replaced by farms, cities, and suburbs to accommodate a growing population, nitrogen pollution in the Chesapeake Bay has greatly increased. Poor water quality has negatively affected important species such as submerged bay grasses, blue crabs, oysters, and various fish species. Nitrogen ends up in the environment mainly through runoff (specifically storm drains), and thereby also ends up in the Chesapeake Bay. Excess nitrogen is one of the leading causes of Chesapeake Bay's poor health. When nitrogen enters bodies of water including rivers and streams, they fuel the growth of algae blooms which leads to low-oxygen (dead zones). These dead zones are harmful to aquatic life in the Bay. Excess nitrogen in our waters, leads to climate change, as it is a greenhouse gas, thus contributing to global warming The Chesapeake Bay is the largest estuary in the United States. To solve this, I have created and designed NSDF, a nitrogen storm drain filter, which reduces the quantity of nitrogen runoff leading to the Chesapeake Bay. Reducing nitrogen levels can save aquatic life, and reduce the effects of climate change.
