Newtown Creek Environmental Analysis

Decent Essays

Newtown creek is a 3.8-mile waterway located on the border of Brooklyn and Queens in New York City and was once a busy center for industrial activity. More than 50 factories were located along its banks, including oil refineries, petrochemical plants, sawmills, and lumber and coal yards. The Creek was also the site of one of the largest oil spill in the U.S. (EPA, 2007). As a consequence, the soil surrounding the area became polluted with toxic heavy metals and polycyclic aromatic hydrocarbons (PAHs) and was declared a Superfund site. The Superfund Program requires responsible parties to perform cleanups or reimburse the government for cleanups led by EPA. Superfund sites are hazardous to human health and to the environment. benz[a]anthracene, …show more content…

When the moisture, temperature, and nutrients are suitable, spores freed from a mushroom germinate into threads of cells called hyphae. As each hypha grows and branches, it forms connections with other hyphae from compatible spores to create mycelia, which mature, gathering nutrients and moisture (Stamets, 2005). The mycelia of the Stropharia rugoso-annulata, otherwise known as the garden giant, are bestowed upon the title of mycoremediator. Its mycelia secrete enzymes such as manganese dependent peroxidase, an enzyme that mineralizes wood and is particularly efficient in breaking hydrocarbon bonds; this mineralization indicates a complete breakdown of the PAHs (Morelli et al. 2012). This fungus has been proven to modify soil permeability and soil ion exchange and to detoxify contaminated soil. It has been identified as one of the most efficient degraders of PAHs among the litter-decomposing fungi, with reductions of up to 70%, 86% and 84% of benzo(a)anthracene, benzo(a)pyrene, and dibenzo(a,h)anthracene respectively (Steffen et al, 2007). The garden giant also remediates the soil by consuming the harmful bacteria that hinders plant …show more content…

Bioremediators need to be able to grow in order to remediate the soil of pollutants. The purpose of this research is to determine whether the presence of Stropharia rugoso-annulata in the soil will support and accelerate the growth of ryegrass in a mutualistic symbiotic relationship. If the growth of the ryegrass is accelerated and supported, the combination of the two bioremediators could potentially accelerate the degradation of PAHs in the soil. Techniques such as soil washing, soil flushing, vitrification, etc., exist to remediate contaminated soil. Although, these techniques are effective, they also disturb the natural environment to some degree. Bioremediation is often accomplished in situ resulting in minimal environmental disturbance. This study is being performed because healthy soil is a limited resource that needs to be preserved and replenished. The state of soil can impact the health of humans, animals, and ecosystems, therefore, it’s important to be able to monitor and control the pollutants in
