Our class went to the Conodoguinet creek and we tested the creek for signs of acid rain pollution, phosphates and nitrates, and dissolved oxygen levels. My hypothesis is that the creek would end up being polluted. But after the testing we did our results showed that the creek was not polluted. some of the tests we completed were water alkalinity tests, critter count tests and rocks that neutralized the acidity of acid rain. We also calculated the velocity of the water.
By calculating the velocity of the water we were able to tell how fast it was going. This helps us determine the health of the creek by allowing us tell if the water is moving too slow to distribute this such as chemical nutrients. If the creek were to be moving too slow there would be no way the nutrients could be evenly distributed through the creek. This would

The third test we conducted were eutrophication tests, phosphate and nitrate tests, and acidity and alkalinity tests. The first one was a ph meter test to see if the water in the creek was acidic, neutral, or alkaline. On the ph meter we got a 7 which is neutral, and that’s good. For the alkalinity test we got a 13 which is good, and for the acid test we collected rocks and got 65 total. Of the 65 rocks only 29 did NOT neutralize acid which is really good so the creek should not be acidic.
We then took tests to tell if the water had eutrophication problems. Of all our phosphate tests we took it averaged out to 0.1ppm (parts per million) which is really outstanding. We then took nitrate tests and they averaged out 0.9ppm which is good. The last tests we took were dissolved oxygen tests and they came out 9.8ppm which shows how much oxygen is in the water and that is very great. So all of our eutrophication tests we took came back positive showing the the Conodoguinet creek is very
The Eutrophication test determines the amount of nutrients there are in a stream, creek, or most bodies of water. When we did the Eutrophication test we got a lot of low numbers. For the Phosphate test they were mostly a 0 with a .1. When we did the nitrate test we got .25, .75, 1, 1.2, 1.5, 1.3, and a .9. for the dissolved oxygen tests they were all mostly high results.
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.
Whites Creek was initially a natural watercourse, concreted to improve sanitation in the surrounding area. Over the years it was transformed into a natural park, with an array of services, including tables for picnics, BBQ areas and a skateboarding zone. The Whites Creek Wetland was also constructed, being a sediment and purification pond that aims to remove water from Whites Creek stormwater waterway and pass it through a natural purification system. This system would then filter the water back in the water channel and out into the Sydney Harbour .
We also did not find a high level of phosphates and nitrates in the water. My group also did a dissolved oxygen test on the water. The velocity of the surface water of the creek is at a normal rate. The Conodoguinet Creek appears to be healthy right now.
To test turbidity, take the tube and put the water in the tube and see if you can see through the tube. If the levels of the tests were normal and good, that would mean the river is
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.
Approximately four-fifths of the Tar-Pamlico River Basin is located within the Coastal Plain region of North Carolina while the remaining one-fifth lies within the Piedmont region. Slow Moving streams surrounded by swamps, forests, low-lying marshes, and estuarine areas characterize the water flow in the Coastal Plain region. The Coastal Plain portion features slow-moving blackwater streams, low-lying swamps, and productive estuarine waters. The larger waterbodies are meandering, often lined with swamps and bottomland hardwoods, and often have naturally low dissolved oxygen and pH. Soils are deep sands that have a high groundwater storage capacity. There are 80 miles of impaired stream in the Tar-Pamlico River basin and all waters in the basin have a supplemental classification of Nutrient Sensitive Waters (NCDWQ
The marshland itself harbors a wide array of ecosystem services. The water in the marshland at the Shawsheen River site has a pH of 5.5. It is slow moving with a speed of 36.88 meters/second. Where the water is moving faster there is more oxygen; whereas, where the water is moving slower, there is more Carbon Dioxide. This is a provisioning ecosystem because when the dam is removed, there will be less carbon dioxide because of the increased water velocity.
This has been a major contributor to the massive loss of life in the Chesapeake Bay waters. The average of phosphate tests were approximately zero and one tenth ppm (parts per million.) The lower the phosphate number, the smaller amount of pollution there is in the water. The average amount of nitrate in the water was approximately zero and nine tenths. The same scenario as the phosphate, the lower the number, the smaller amount of pollution.
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,
Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters
Introduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.
Practical I: Acid-base equilibrium & pH of solutions Aims/Objectives: 1. To determine the pH range where the indicator changes colour. 2. To identify the suitable indicators for different titrations. 3.
Introduction The goal of the experiment is to examine how the rate of reaction between Hydrochloric acid and Sodium thiosulphate is affected by altering the concentrations. The concentration of Sodium thiosulfate will be altered by adding deionised water and decreasing the amount of Sodium thiosulphate. Once the Sodium thiosulphate has been tested several times. The effect of concentration on the rate of reaction can be examined in this experiment.
