MA# 3: Is Storm Water Damaging the Puget Sound? Today, storm water runoff is the number one cause of pollution in the Puget Sound. The pollutants contained in storm water runoff are mainly caused by urban runoff, factory farming, and chemicals. Urban runoff can produce pollutants such as gasoline, grease, ammonia, manure, toxic chemicals, and pesticides. In factory farming, the main problem is the production of manure which is extremely bad for the Puget Sound because of the high levels of nitrates it contains. Chemicals carry numerous pollutants which can alter marine life genetics and harm human health. Alternatives to the problems lie in green infrastructure, greenroofs, bio-swales, and porous concrete; however, the solution to the …show more content…
Storm water is a great danger to the environment because it does not receive any treatment before entering waterways. A storm can overload the system, causing it to reach its max capacity. The water treatment plant is then forced to let the overflowing, untreated, water dump into the river. This leads to an almost opaque water, like that found in the Puget Sound. There is an average of 900 billion gallons of untreated sewage water entering larger bodies of water each year in the United States (Barnett). The rain that falls on surfaces drains into bodies of water through storm water collection systems, usually, without treatment. There is a strong relationship between concrete thickness and imperviousness in residential areas, leading researchers to believe that roads create impervious surfaces. When rain down the streets and rooftops, it absorbs all the harmful materials from those surfaces and flows into the major bays and the Puget Sound. The Environmental Protection Agency estimates the remodeling of the aging water system would cost between $300 billion to $1 trillion over the next 20 years (Barnett). The effects of urban runoff are immensely damaging to the Puget Sound. The list of substances and chemicals that can cause damage is extensive. The effects of urban runoff are even more daunting than the causes. The effects include an increase in temperatures, algae blooms, lowered oxygen levels, injured marine life,
The Chesapeake Bay is a 200-mile-long estuary extending from Norfolk, VA to Havre de grace Maryland. On average this bay contains about 68 trillion liters of water. This bay is the largest estuary in North America. It inhabits more than 3,000 species of plants, animals, and fish. “Since the early twentieth century, the Chesapeake Bay has experienced serious environmental degradation. Problems include large reductions in sea grass, reduced amounts of finfish and shellfish (especially oysters and crab), seasonal depletions in dissolved oxygen, and increases in sedimentation.” (Atkins & Anderson, 2003) These changes are brought on by pollution (Eutrophication and Toxic Contamination), development, deforestation, and agriculture. And according
It is their home, their thriving place. According to the National WIldlife Federation, ¨The Bay supports 3,600 species of plant and animal life, including more than 300 fish species and 2,700 plant types.”. Not only does the wildlife depend on the bay, but humans do as well. The Chesapeake Bay contains a 64,000-square-mile watershed, this watershed provides large amounts of drinking water for us in Maryland, along with several other states. Everyday, the condition of the water declines, meaning the home for wildlife and our drinking water does too. The Chesapeake Bay Foundation pointed out that, ¨Toxic chemicals are constantly entering the Chesapeake Bay and its rivers and streams via wastewater, agriculture, stormwater, and air pollution. These harmful chemicals, such as mercury, PCBs, and PAHs, do not break down easily and persist in the environment for many years, impacting not just fish and birds, but humans as well.¨. How important does the restoration of the bay sound
Scientists and researchers began giving a large volume of effort and look into the extremely complex problems that face the Chesapeake Bay. When research for the improving and saving of the Bay’s overall health began it seemed very simple and there were only a couple of problems. The problems included nutrients from agricultural runoff; these nutrients were phosphorus and nitrogen. The combination of the nutrients in the Bay caused a large volume of algae that choked some of the marine life. While bringing in algae the nutrients also killed grasses on the seafloor. These seafloor bed grasses that once covered more than half of the Chesapeake Bay’s floor now only covered a tenth of their original area. Though the estuary was having problems it did not receive the terrible pollution from industries that many large rivers and lakes do in other urban areas (Brown, p. 397).
Nowadays, the most water pollution in Washington States comes from storm-water runoffs. Storm-water discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops. During rainfall and snow events that often contain pollutants in quantities that could adversely affect water quality. Moreover, toxic chemical runoff from storm-water has an impact on organisms and human health. Therefore, this essay will focus on Puget Sound storm-water pollution, how they impact on living organisms, some solution of storm-water pollution, and why do we should care about of Puget
Many of these impervious surfaces have drainage systems that run directly into the watershed. As shown above in the center picture, there is direct drainage from the street to the watershed with no type of filtration, which in return has cause the glistening polluted puddle in front of the drainage pipe.
Furthermore, factory farms pollute drinking water sources. Manure and fertilizers are rich in nitrates and phosphates, which are very unhealthy for living things. They pollute groundwater sources by seeping in through lagoons of waste sewage that factory farms create. Lagoons of animal feces and spent fertilizers are a very cheap way of dealing with waste (NRDC). The chemicals travel through the soil to groundwater that the local communities depend on. Ingesting nitrate tainted water will lower the amount of oxygen a person can intake. This can lead to death for infants. Some of the pollutants can reach open waters if they are carried by rain or irrigation water, called runoff. Runoff pollutes ponds, lakes, oceans, and other open bodies of water. Polluted waters with high levels of nitrates kill fish, aquatic plants, and other aquatic organisms because they experience the same problems with oxygen intake. High levels of phosphorus in our waters cause algae blooms in open bodies of water. Algae blooms disrupt the ecosystem in the water and kill the organisms living in the water. They use up all the oxygen in
One of the most poorly understood causes ocean pollution is urban runoff. Urban runoff is also one of the leading causes of ocean pollution, Surfrider agrees, “Urban runoff is often the primary source of ocean pollution. The Ocean Friendly Gardens (OFG) Program educates and assists people in creating landscapes that utilize native plants, permeable ground covers and water retention features to prevent urban runoff, create wildlife habitats and design beautiful spaces” (Surfrider). Surfrider has a program called The Ocean Friendly Gardens where Surfrider
The importance of the Chesapeake Bay is introduced. The bay is home to a large amount of seafood businesses, and many people fish the bay and its tributaries for sport. Grass beds are essential to many of the organisms living in this ecosystem, but are being destroyed by pollution. Agriculture involves more than a fourth of the bay's watershed. This makes agricultural runoff a big focus. Excessive nitrogen and phosphorus causes eutrophication. These nutrients come from pesticides and sewage also. A goal was set in 1985 to cut back the percent of nutrients being put into the bay by these two sources. It is thought that redirecting the flow of soil with nutrients in them will reduce the runoff, but if the nutrients seep into groundwater they still get into the Chesapeake Bay. Farmers have ways to help reduce these nutrient levels, but it is not the cheapest way to farm, so not all farmers are doing their part to save the bay. Another contributor of runoff land development. Runoff can occur from exposed land being prepared to be developed, or because of what has been used to replace what used to naturally be.
The bay has fifty major rivers and streams that drift into it. Nitrogen and Phosphorous are rapidly getting released into the bay. Most of the Nitrogen and Phosphorous comes from agriculture, air, and sewage. The excessive nitrogen and Phosphorus degrade the bay's water quality. Each year roughly three hundred pounds of polluting nitrogen gets into the Chesapeake Bay. Just like the Everglades the Chesapeake's water is in danger.
Building additional vegetation areas to create green filters is a solution that will decrease the amount of pollutants in the Chesapeake Bay Watershed. This will be effective given the fact that soil has the ability of breaking down nutrients into harmless substances and plants are able to facilitate the process of water infiltrating back into the ground and stopping storm-water runoff. Thus, more green areas will be able to retain and control the amount of pollutants going into the bay.
Chemicals harm the growth of plants and animals, chemicals can lead animals to death. Many of the water animals
The runoff carries pollutants such as nitrogen, phosphorus, and sediments into the Bay. In urban areas the standard city block creates five times more runoff than a forested area. About 30% of runoff in an urban area is evaporated, 55% stays runoff, and the other 15% soaks into the land with a variation of deep and shallow infiltration. About 40% of runoff in a forest evaporates, 10% stays runoff, and the extra 50% seeps into the ground with a variation of deep and shallow infiltration. The runoff is actually the fastest growing source of pollution for the Chesapeake
This spring, record breaking floodwaters along the Mississippi River caused massive damage in nine states, totaling over $25 billion dollars in damage (Watts, 2011). In most areas the floodwaters have receded, however there is concern that even a little rain could cause more flooding due to the already saturated land. As cities and towns are beginning the restoration process, one thing caused by the flooding waters cannot be restored. Pollutants’ such as nitrogen from fertilizer, due to this area being primarily composed of farming land, is making its way toward the Gulf of Mexico. Every year pollutants traveling in the Mississippi River enter the Gulf and contribute to the Coastal Dead Zone; however, this year the Dead Zone in the Gulf

This is especially true for water runoff from power washing in Los Angeles. Aside from the waste material being washed off, such as oil, grease, mold, paint, etc., the water will be contaminated with the chemicals used in your cleaning agents, which can pollute the environment if allowed to get into a storm drain leading to a waterway. In addition, these chemicals could damage your lawn, garden plants or trees, if proper protections aren't in place. Even if the water is "clean," your landscaping could suffer from flooding or an unwary pass through from a high pressure washer in Beverly Hills.
