Case 2: Chesapeake Bay watershed System Complexity, Data, and Impairment Description The Chesapeake Bay watershed is an example of a complex modeling system that consists of a large watershed (165,759 km2) with flow-regulated rivers, large urban centers and expansive rural areas, and an estuary (US EPA, 2010). The Chesapeake Bay TMDL allocates total nitrogen, total phosphorus, and sediment loads to reduce the size of the oxygen-depleted zones in the bay to restore its living resources. As such, estimating nutrient loads from all sources (air and land) and assessing their effect on the bay’s aquatic life requires the use of an integrated modeling framework. Because of the areal extent and system complexity of the watershed and the estuary, the Chesapeake Bay TMDL is one of the most complex TMDLs conducted in the United States.
Virginia General Assembly in 1988 enacted “The Chesapeake Bay Preservation Act (Bay Act)” as a pivotal component of Virginia 's non-point source management program. The Chesapeake Bay Preservation Act led to the development of land use regulations which was adopted in 1989 and were amended in 1991, 2001 and in 2012 as part of the Integration Bill The Bay Act program is designed to improve water quality in the Chesapeake Bay and other waters of the State by necessitating the use of operational land management and land use planning. At the core of the Bay Act is the notion that land can be used and industrialized to curtail adverse impacts on water quality. The first sentence of the Bay Act serves as a theme for the whole decree: "Healthy state and local economies and a healthy Chesapeake Bay are integrally related; balanced economic development and water quality protection are not mutually exclusive." Virginia aimed the Bay Act to improve water quality and still allow sensible development to continue.

I am a student at Beville Middle School, Prince William County, writing you today to express my deep troubles over the Chesapeake Bay. My biggest concern is about the blue crabs in the estuary. Published articles indicate that the blue crab population is reducing due to over-harvesting and reduction of suitable habitat. Even though the blue crab population has made a remarkable comeback in recent years, it is vital for us to act by any means necessary to save the population of the blue crabs.
This is another way of pollution. In Monroe County the watershed are in nature and are protected and full of life. Everything connects pollution and locations affect each other and these two watersheds are different when it comes to these issues. The location affects the types of pollution around the watershed. The Petaluma watershed is also known as a tidal slough, and because of where it is located once in a while will get washed up animals and the tide will make the water murky which affects turbidity.
The Chesapeake Bay Oyster Restoration Project aims to help locate a healthy habitat for oysters. The Chesapeake Bay has been affected by the long-lasting drought in Maryland, which influenced the water quality. The drought increased the salinity of the water which has a negative impact on the oysters. According to the National Oceanic and Atmospheric Administration, “the native oyster is an extremely resilient species, able to tolerate wide variations in salinity and temperature—but it has not been immune to the pressures of disease, overharvesting, and pollution in the Chesapeake Bay. As a result, native oyster populations in Chesapeake Bay are at less than 1% of historic levels” (A,& Blue Water Media).
In Cleveland, Ohio there was a fire that occurred on June 22, 1969, around 12pm on the Cuyahoga river. People called it the “burning river”. The river caught on fire because there were floating pieces of debris that was slicked with oil. The debris ignited by sparks that came from a train that was passing over the river. The reason it happened is from years of people dumping pollution into the river.
Over the years, chemical and industrial plants have been built along the shores of Niagara which also pour chemicals into the river compromising our water quality. Although many policies have been created and set in place, there is still waste being dumped into the Niagara which is affecting our cities water quality. The quality of our air is also an environmental issue within Niagara, potential sources of air pollutants include road salt, industrial chemicals and waste, fuel, pesticides and fertilizer. In the Niagara area the surrounding industries release toxic chemicals and contaminants into the air which
Florida has a lot to boast for with it’s beautiful beaches and vibrant wildlife that attracts many tourists from around the world. This attraction to Florida, however, is being plagued by the overwhelming amount of pollution that Florida is facing. This pollution can range from the simplest form of a trash littered beach that almost any resident of Florida can attest to or it can take the form of something much greater. This greater form of pollution is the massive outbreak of green algae that has occurred in Florida with one of the most recent back in July of this year. The algae outbreak is caused by “fertilizer sewage and manure pollution that the state has failed to properly regulate” as stated by Earthjustice spokeswoman Alisa Coe.
The Chesapeake Bay is the largest estuary in the United States located between Maryland and Virginia lying inland from the Atlantic Ocean. It has more than 150 major rivers and streams covering parts of six states New York, Pennsylvania, Delaware, Maryland Virginia and West Virginia. Nearly 17 million people live in the Chesapeake Bay watershed and affect the waters pollution. The Bay is very important to the economy of Maryland and Virginia providing economic resources, including crabs, oysters and rockfish, as well as recreational activities in and around the water. Due to the increase in the amount of pollution in the water, the wildlife and the recreational activities in the bay have slowly went down.
Rivers, specifically, the potomac river is main water systems that I have chosen to report. The potomac river surrounds multiple states including Virginia, Washington D.C. and Maryland is one of the largest rivers in the eastern coast of the United States. A report from the nonprofit advocacy group American Rivers, noted what locals have said for years: “that urban development is funneling tons of polluted rainwater to the river, that chemical fertilizer and manure from farms make matters worse, and that wastewater overflowing from sewers, along with pharmaceuticals flushed down toilets, contribute to dead zones in which marine life dies and might cause fish to switch sexes. Some male fish in the river mysteriously have eggs.”
Farmers began to grow their crops in San Joaquin Valley for more than 100 years. Farms in the valley produce mostly vegetables, fruits, nuts, and dairy and they are the main manufacturers in international markets and major suppliers in the United States (Hanak & Arnold, 2017). Farmers are using polluted groundwater to grow their crops and harming the environment by drying rivers and causing people to get health problems. The reason that there are pesticides in nitrates in groundwater in San Joaquin Valley may be the fact that there is a long history of farming and irrigation and generally permeable sediments (Burow & Dubrowvsky, 2014). The first organization that noticed the growth of nitrates in groundwater is the Regional Aquifier System Analyses Program.
In the seventeenth century Chesapeake women had different roles than other colonial women. Chesapeake women were expected to work in the house, raise their kids and work with their husbands in the “tedious care of tobacco plants.” (page 13) Unlike in the English society, they lacked a sense of “housewifery” due to the fact that they had the lack of spinning wheels and churns. (page 13) Since mortality rate was so high it was excepted of not just men but especially women to marry multiply time.
Why? It’s because, the chemicals goes into the soil and makes runoff from the stormwater, and gets into the water, and pollutes it. The chemicals make the water polluted, which also harms the wildlife. Other things including sediments, dirt, and muck also get in the water
Finally, many of our wetlands are in the process or have already been destroyed by us with all of the plastic that we throw onto our local streets. According to Jacques Cousteau in his article “The Bounty of the Sea” he explains that the surface of the ocean has a thick film of decayed matter on it. Many people aren’t going to think about this, but if the ocean has a film on top of the water the water isn’t going to be able to reach the skies through evaporations resulting in global drought resulting in many more problems. Cousteau says “Certain reefs that teemed with fish only ten years ago are now almost lifeless. The ocean bottom has been raped by trawlers.”
