Yasmin Bateman Water Essay Why is stormwater pollution a problem and what can YOU do to prevent it? Stormwater is water that surfaces in a large quantity that results from heavy rain. Storm water runoff gathers and conveys litters, animal wastes,dirt and other pollutants as it flows.Storm water pollution is one of the biggest problems in the world today and many animals die or are harmed from it. The polluted stormwater deteriorates our waterways, like rivers , lakes or ponds. There are many…

First, the runoff going into Lake Erie must be reduced. The major area of runoff comes from farms. The cause for runoff is rain and the rain washes away all pesticides, which enter into lakes and rivers: “In both cases, heavy spring rains washed away tons of fertilizer from farms. The runoff drained into rivers that fed the lake. Phosphorus in the fertilizer spurred cyanobacteria growth. Hot summers and other factors made matters worse” (Kowalski 34). As a result of pesticide entering into lakes…

Rain gardens and bioswales are examples of detention ponds. Rain gardens are shallow, vegetated basins that are frequently installed adjacent to impermeable surfaces such as roads, sidewalks, and parking lots. A runoff inlet allows the stormwater to pool in the rain garden and then either slowly infiltrate into the ground or be absorbed by the vegetation (Yang, Dick, McCoy, Phelan, & Grewal, 2013). Bioswales…

the Foxstone Creek in Vienna Virginia. Although there are many different problems that have occurred in this creek, the problem that we noticed that is the most impactful, is the amount of erosion on the creek. Erosion is the process by which the surface of earth is being worn away because of water, ice, wind, waves, and other natural forces. Erosion can also be caused by other things such as, non paved roads, steep slopes, agriculture purposes, and or construction, but we infer that most of…

Watershed from 1989 to 2016. As stated previously, impervious surfaces reroute runoff, which can impact sedimentation, erosion, and pollution processes in local environments. Over the past few decades, urban development has had negative effects on the local watershed (Coffee 2010). Based on Figures 2 and 3, it can be asserted that this environmental stress correlates with the local, urban sprawl displayed…

variety of ways depending on the specificities of an area. For this research, these areas will specifically be different types of nodes identified along a linear stretch of a suburban area. As identified by Emily Talen, a node prime for sustainable development falls into one of four categories: a previously identified “core”, an area around existing transit stops, areas where “surface parking lots make up a significant portion of developed land area” and “shopping centers that are within a…

rural areas to cities is causing the cities to become congested and polluted. The rapidly expanding population and overcrowded slum have hasten the urban development where old buildings are demolished and deforestation is carried out to provide more space for development to cater the needs of increasing population. As a result of urbanization, congestion, pollutions, climate change and emissions inevitably beset every city and historic cities are of no exception. Many historical urban areas…

This creates a self-reinforcing cycle. The constant demand for expansion places strains on potential imitations such as limited space and the hazardous effects of having such large amounts of people in a restricted area of a city. Cleanliness was and remains to be a constant priority. Cities have made us smarter in the sense that we have created ways to keep places clean despite the constant use and traffic. Glaeser explains that, “In the 1880’s, New York’s streets…

Heat of Combustion of Magnesium Hypothesis: Hess’s law states that “the enthalpy change for the conversion of reactants to products is the same whether the conversion occurs in one step or several steps” (DiGiuseppe et al,2012,p.314 ). A series of two experiments will perform in this lab in order to find ΔH1 and ΔH2 . In addition, ΔH3 will be obtained by reference. It is predicted that the combustion of magnesium will have a negative enthalpy, since combustion is an exothermic reaction. Also…

Introduction: The world is urbanizing rapidly; the present population living in urban areas is 54%. The more urban an area, the more concretized it is. Urban areas are quite warmer than the rural counterpart, the natural ecosystems are being replaced by buildings and other structures. There is significant temperature differences between city centers and their surrounding countryside and surface temperatures can be much greater in high density suburbs compared to low-density suburbs; the reason…
