My 8th grade class went to the Conodoguinet creek to test if there was any pollution in the creek water. Before we went my hypothesis was, “If we go to the Conodoguinet creek and test the water, then the creek will have little to any pollution in it because we haven’t had a monstrous storm in the past few months so there wouldn’t be an excessive amount of acid rainfall or runoff” There are three types of macroinvertebrates ( an invertebrate fauna - animal of a particular region - that can be captured by a soo - which is a certain net or sieve - ) that we were looking for, Group 1 ( which is pollution sensitive - they cannot have any pollution- ), Group 2 ( which is somewhat pollution tolerant - they can live with some pollution-) and Group …show more content…
phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with. Dissolved Oxygen is another thing we tested for, that 's how much oxygen gets mixed within the water ( Ex. rapids - the white part of the rapids is the oxygen mixing with the water- .) We also tested how fast the water was moving or the ( speed/velocity. ) We were going to test it by using a bamboo pole with a string ( with a certain length ) and a bobber on the end and see how long it takes for the bobber ( from its full length ) to hit the bamboo pole. To find the actual speed of the water you take the length of the string divided by the time ( sec/centi
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
The variables measured are nitrate, nitrite, total phosphorus, ammonia and transparency. Harrison also states that river and Lake Eutrophication is a problem across most of Europe because of excessive nitrogen and phosphorus levels from agricultural, industrial and domestic effluents. Harrison states that natural organic matter is present in most natural eco systems.
On October 8th, 2015 our class took a field trip to the Conodoguinet Creek to test the water quality. We did 3 experiments to help us conclude the quality. During the first experiment we observed the different types of organisms in the creek. We also took tests for eutrophication in the water. Another experiment we performed were acidity tests.
ulimba Creek is the largest creek in Brisbane measuring to only 122km². It is located in the eastern and south-eastern areas of Brisbane and generally flows northwards into the Brisbane River. There are also a number of significant wetlands systems in the catchment in the upper and in the lower catchment. The creek is, at present, affected primarily by urban and mechanical advancement. In the past the creek hallway was broadly cleared for crops and after that grazing in the early moments of the most recent century with some remainder of vegetation remaining.
The Catawba River and Pollution The majority of avid paddlers, especially those of us near the U.S. National Whitewater Center here in Charlotte, know that the water quality of the Catawba River is considered “sketchy.” We have grown used to seeing the occasional, inexplicably dead catfish along the river banks and do not seem to question it anymore. What we don’t always realize is that the water quality is much worse than we had originally thought. For example, untreated sewage spills and line leaks from new developments along the river end up contaminating the nearby water, and therefore affect everything downriver from the sites.
A subtropical wilderness with grass marshes, forests thick with trees hundreds of years old and hardwood hammocks (trees that only grow a few inches tall but packed very close together but can take up acres). Seems like a place to protect. Ever since the 1900 draining of the everglades, the ecosystem has shrunk by 50%. People did not see how important the Florida everglades where. The effect of the polluted water in the everglades is causing problems for both people and the inhabitants of the everglades.
The algae comes from fertilizer that washes in the water from huge farms near the lake. The algae absorb a lot of oxygen from the water when they run out of steam and leave spots called “Dead Spots” which are areas where there is no oxygen so fish can’t breathe. Though this isn’t even the worst part, some of the bacteria that are in the algae get into our water and cause nondrinkable water. If someone were to drink it, they would get very sick and maybe have fatal outcomes. All hope is not lost though because Scientist are working very hard to solve how we can clean the lake.
Clearly, pollution is still a huge problem facing the Great Lakes ecosystem. Chemicals from agricultural uses get in the lakes. The fish digest the chemicals; we catch and eat the fish. Therefore, we have the toxins in our body and eventually die.
Hudson River PCB Pollution is Affecting Wildlife Bird Species Introduction Studies over species in the Hudson River ecosystem have increased in recent years. This is done in return to the large amount of PCBs that have been found in the Hudson River. Polychlorinated Biphenyls or PCBs are a group of 209 organic chlorinated chemicals (DHS, 2016). PCBs are usually an oily liquid or a solid, which are colorless or have a light yellow color, with no smell or taste (DHS, 2016).
The Monroe County and Petaluma Watershed are different in ways that which affect the health of the watershed. Pollution, location, and use are all important aspects to consider when observing watersheds. The pollution and location will affect the health of the watershed and the nature around it. This affects what the watershed is used for like biodiversity and general water uses. Watersheds are important to nature and are a very big water source.
Sediment and nutrient pollution is a huge contributor to the poor water quality in the bay. While some nutrient variation is expected due to normal changes in weather,
Based on observing the organisms living in the creek, the water quality of the U-High creek was excellent. However, not all bodies of water have excellent water quality. Most bodies of water with below average water quality are affected by humans. One way humans could negatively impact water quality is through runoff. It is common for farmers to put many pesticides and fertilizers on their crops, but these substances can be washed into rivers and add extra nitrate and phosphorus into the water.
Pollution rough draft Pollution is one major thing that is threatening our earth. It can take millions of years to recoup. There are many types of pollution, including water pollution, land pollution, and light pollution. Pollution is mainly caused by toxins, gases,trash, and litter. It harms our Earth, and damages ecosystems.
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
Both biotic, and abiotic effects are put in this acidic cycle. First and foremost, studies show that dissolutions rates shown by planktonic organisms have increased. With organisms like plankton disassembling, is shows a biotic effect towards the ecosystem. Since Zooplankton
