Recommended: Water pollution and associated problems

Yesterday morning, my classmates and I went to the conodoguinet creek. We went to the creek to find out if there is pollution in the water. We took 3 tests to find out if the water was polluted or not.

My first experiment was on a critter count. The critter count involved us to take rocks out of the creek and count all the critters that are on the rocks we find. If we find a lot of group 1 critters, critters that can’t be by pollution, then the waters aren’t polluted. If we find a lot of group 3 critters, critters that can be by pollution, then the waters are polluted. Group 2 critters are critters that can be in both, but not a lot of pollution. My group and I found lots of group 1 critters(63) which was a good sign. We also found 26 group 2 critters, so the water was polluted, but not by a lot. We found 13 group 3 critters, so we know now that the water is slightly polluted, but it is still clean. …show more content…

Pennsylvania has the most acid rain in the country, so it is not a surprise if the creek was polluted, but it’s not. It could be because of limestone rocks, or rocks that neutralize pollution in waters. Are next experiment was a eutrophication Test. A eutrophication is an enrichment of an ecosystem with chemical nutrients typically compounds containing nitrogen, phosphorus, or both. In this test we took samples of water into clear measurable tubes. There is 3 things we tested with water, Phosphate, nitrate, and dissolved oxygen. Phosphates and nitrates are examples of polyatomic ion. Phosphates and nitrates are found in fertilizers and some detergents. We tested for them and we didn’t get big results, so we know that waters aren’t polluted. There was a lot of dissolved oxygen, which is good, because that is what fish need to

    Television commercials, print ads, and billboards in the Washington, DC, area are asking residents to connect two things many might find unrelated: lawn care and seafood. In one commercial, a man stuffs a big plateful of grass in his mouth after a voice-over says, “Spring rains carry excess lawn fertilizers through our sewers and rivers and into the Chesapeake Bay, where the blue crab harvest has been extremely low. So skip the fertilizer until fall, because once they’re gone, what’s left to enjoy?”(Environment, p. 7)

    Pollution of the earth is a major limiting factor to the abundance of life on earth. Pollution of all kinds can kill wildlife, causes habitat degradation or destruction, create navigational hazards, and even destroy economies and human health (https://marinedebris.noaa.gov/sites/default/files/MD_Tracker_App_Flyer_FINAL.pdf). These effects, though, are most evident in marine environments. The dumping of waste, especially plastics, causes severe stress to the world’s oceans, rivers, lakes, and ponds. While scientist cannot know the exact extent that pollution is affecting the environment, one way in which scientists can go about determining the pollution of a region is Citizen Science, as Dickerson

    About 80% of the State’s surveyed freshwater rivers and streams have good water quality that fully supports aquatic life uses, 17% have fair water quality that partially supports aquatic life uses, and 3% have poor water quality that does not support aquatic life uses. Ten percent of the surveyed rivers do not fully support swimming. The major sources of impairment are agriculture (responsible for 53% of the impaired river miles), urban runoff (responsible for 16%), and construction (responsible for 13%). These sources generate siltation, bacteria, and organic wastes that deplete disssolved opxygen.

  • A Summary Of Pollution In The Chesapeake Bay

    In 1968, a survey was conducted. It found that pollution in the Chesapeake Bay cause $3 million annually in losses to the fishing industry. Meanwhile, the U.S. Bureau of sports fisheries measured DDT, a pesticide, in 584 of 590 samples. These levels were nine times the FDA limit. In 1969 bacteria in the Hudson River was 170 times the safe limit. Over 41 million fish were killed. This included the largest ever with 26 million from four food processing plants in Thonotosassa, Florida dumping discharges into the lake. South of Cleveland, Ohio the Cuyahoga River burst into flames causing damage to railroad trestles. The cause is unknown but investigation pointed to a discharge of highly volatile petroleum derivatives that could ignite easily.

    'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling

Microcystin, a toxin that causes liver problems, is produced by the growths have caused major health concerns for wildlife and people using the lake. It is our moral obligation to clean up this mess or it will continue to harm the wildlife and environment in and the lake, as we are the one’s solely responsible for it. Organizations such as the Ohio EPA and Buckeye Lake for Tomorrow, have taken a notice to the pollution of Buckeye Lake and are formulating plans to return the lake to its former glory.

  • UHS Water Quality

    421 Words  | 1 Pages

    The water quality of the UHS creek is excellent. But even though the UHS has an excellent water quality, it doesn’t mean that all creeks have excellent water quality. Humans can negatively impact water quality in several ways. One of them is by farm runoff. Farmers sue pesticides and fertilizers on their crops. When it rains, these chemicals are washed into nearby rivers. This increases nitrates and phosphates in the water. Algae use these chemicals to thrive. They block sunlight to other living organisms in the creek, which need sunlight in order to survive—like photosynthesis. When the high number of algae dies, bacteria thrive on the dead algae and use all of the oxygen in the water. Because of this, many animals living the creek die. This entire process is known as eutrophication. Another common human source of pollution in creeks is factory runoff. Some factories use water to power machinery or cool machinery down. When this water is put back in the river it contains harmful chemicals. Also, the water is sometimes warmer than the rest of the river and lowers dissolved oxygen in the river and upsets the balance of life in water.

  • Pond Water Lab

    The park in which the pond water was gathered is in an urban area in providence Rhode Island. The current state of the park is slightly polluted with people traveling through it every day. Common activities in the park can be, but are not limited to, walking, running, or driving through the park, swimming, boating, or fishing in the water, or feeding the numerous amount of wildlife throughout the park. It is assumed that all of these activities affect the ecosystem negatively. A lab was conducted to study the very effects that humans have on this quant ecosystem. Two large buckets of pond water were gathered to the site of the lab. The individuals then studied the life in the buckets that could be easily sought out, such as, large snails, frogs, and even a fish. These organisms were sketched and noted. Then the individuals took out microscopes to view micro organisms in the pond. These organisms were so tiny the individuals couldn't see them with the naked eye. A lot of macroinvertebrates and algae were discovered and noted at this point. In the end, about 28 organisms were found in total and compiled into a large chart. This chart was then used to create a trophic level pyramid (a

    The phenomenon of soil erosion will create the sediment that can wash into the water, which will cause the problems to the aquatic life. In order to reduce the sediment during building new structure or landscaping, the developers should use the tarp to cover the mound of dirt. As the result, the rain and wind do not carry the sediment into the flowing water. The developers also should not alter the stormwater pond as it can impede the ability of the pond to hold the stormwater runoff.
