I believe that Conodoguinet creek is polluted, but only very slightly. In 3 different experiments, my group tested the quality of the water. Below are the results.
In the first experiment, my partner and I were retrieving rocks from the Conodoguinet creek and observing the organisms on them. We were doing this because there are organisms that cannot survive in pollution. Those organisms are called group 1 organisms. There are 2 other groups. Group 2 organisms can survive in slightly polluted water, and group 3 organisms can survive in any water. If we found a lot of group 1 organisms, than that would tell us that the water was not polluted, or if it was, then it was only very slightly polluted. When we had finished observing the rocks, we noticed that we had found more group 1 organisms than group 2 or 3 organisms. That means the creek is not polluted, or if it is, then only very slightly.

We had to get exactly 25ml of water from the creek, and calculate the PPM of dissolved oxygen in it using a test kit. So, we went down to the creek, got exactly 25ml of water, and then we brought it back. We had to break a dropper in it and watch the colour of the water. We found that the colour matched 12 PPM on the scale; a deep blue. We collaborated with the other groups, and wrote down the other groups’ results to compare. We calculated that the average pH for the creek water was 7; entirely normal. We did some other stuff, like finding the number of rocks that neutralized acid in the creek, and vice
The pH scale is 1 to 14, 7 being the best quality. To the right is a pH scale. 7 is what the water should be. 7 is also what we had for the creek average. We had a higher number of rocks neutralizing acid (limestone is the stone found mostly in the creek) than the ones that don’t. this means that the acid rain we get is mostly neutralized by limestone in the stream. We get acid rain from Philadelphia. This is because of the massive steel companies. All of the toxic smoke comes over and comes down in the conodoguinet as acid rain. So the creek is non-acidic and non-alkaline.
The local area is City of Lake County is acceptable to many Floridians the state’s with fourth largest lake known for bass fishery with many lake beaches for recreational interests such as swimming, boating, and water skiing. The government established the Safe Drinking Water Act of 1986. Environmental Protection Agency (EPA) is required to set standards for drinking water quality as well of oversee all states, localities, and water suppliers who implement these standards. Lake County Florida there is many homes that rely on city ground water while others may have a well system in place. Contamination have impacted to the lakes over many decades led the lake to be
Our data clearly shows that the water quality is pretty good, and the ecosystem is fairly descent. The MSHA gave Sawmill Creek a 73.5 out of 100 for the habitat once we added up all the numbers from the questions we answered, giving us the conclusion that the ecosystem was fairly descent. The LabQuest gave us a pH of 6.88 and a DO of 10.85 ppm, and the chemical test kit gave us results of 7.5 for the pH, and 5 ppm for DO. Both of the pH tests gave us results around 7, which is the neutral, and is what you want. The DO is where we got 10.85 ppm for one, and 5 ppm for the other. A good result is 10 ppm, so with these results, we can conclude the that DO is somewhat decent, with both the results put together. The average velocity of our ten meter area of the creek was .29 m/s. A velocity of .29 m/s is a medium speed, making the water not to fast so creatures can not survive, but not so slow that the water just sits, creating bad filtration for the water. The turbidity of the water was also very good, with the seeing distance of over 100 centimeters using the turbidity tube. All of those tests put together make the water quality result very good. The air temperature was 24.7 degrees celsius, and the water temperature was 23.8 degrees celsius. This shows us that the stream was quite shallow, because of how close the air and water temperature was, but still enough of a difference so it was not to warm for aquatic life. With algae being the only aquatic plant we found, and finding sedges, alsike clover, milkweed, red osier dogwood, and speckled alder on the shore, we can say that these plants did not impact the water quality to an extent of affecting the water quality that much, or even at all. The macroinvertebrates in the water; crayfish, mayflies, leech’s, and 3 different egg species, did not seem to affect the water quality too much, if at
On our following field trip to the Conodoguinet Creek, our mission was to determine if the creek was polluted or not. We tested different kinds of experiments with measurements to determine, in our opinion if the creek was polluted. We would then travel to different stations to collect the following data that would reveal the truth about the creek. If the Conodoguinet Creek is polluted then the phosphate level will be high.
The water quality of the U-High creek was excellent, but not all bodies of water have excellent water quality. Humans can pollute water by farmers putting pesticides and fertilizers on their crops. Putting fertilizers on the crops pollutes water, because when it rains the pesticides and fertilizers get washed off and carried into the water, and this adds nitrates and phosphates to the water which is called eutrophication, and it increases the amount of algae in the water. When there is an excess amount of algae in water, there is an excess amount of bacteria the uses up most of the oxygen which kills plants and animals. (River Quality and Pollution,2016) The second way humans pollute water is when it rains there is runoff, and all of the pollution on the ground get carried into the water. Runoff is when it rains the soil and other things get carried to other places. An example of runoff is when there is a heavy rain, the soil sitting on the sides of a hill loosen and slide down the hill toward the bottom causing a buildup at the bottom of the hill.
The quality of water in the U-High creek was excellent. In other water areas the water quality might not be the same. There are different ways humans can pollute the water. Runoff is a good way to pollute the waterways. When you litter on the ground rainfall will pick up the trash and take it to the water. This then makes the water quality go down.(Howard Perlman, May 2, 2016) Another way humans can pollute is with pesticides from farmers. They spray these pesticides on the plants and then rainfall takes the pesticides from the plants and brings it to the water. This then makes the nitrogen and phosphate levels go up and bring the amount of algae in the water. Thus bringing the amount of oxygen in the water down.(Arthur S. Brooks, 2016) Next
Which is important because the human body is approximately 7.4 on the pH scale. I came up with the hypothesis stating that: if the pH is more basic than more oxygen will be formed at the five minute mark if the solution was acidic. The experiment tested the levels of oxygen formed after one, two, three, four, and five minutes and in pH levels of two, four, seven, nine, and eleven. Each group tested this and we eventually complied our results in order for more accuracy.
Due to the easy accessibility of water in Smalltowne, many people have taken the local watershed for granted. As the population and businesses have grown, the waterways in the town have become more and more polluted. Without noticing, the activities of the local people and industries have affected the waterways negatively. There are several causes of the increasing pollution in the streams, lakes, and waterways in small towns. Two of the major causes of the local pollution are oil spills and toxic waste. Therefore, the town should use better containing and delivering shipments and shut down nuclear power plants in order to solve the increasing problem of water pollution.
This article showing some of the pictures related to contaminant water. Contaminants entering the natural water, cause a change in the physical properties of the medium (violation of the original transparency and coloring, odors and flavors, and the like); change in chemical composition, in particular the appearance of harmful substances therein; appearance of floating substances on the surface of the water and sediments at the bottom; a reduction in the water of dissolved
Physical and chemical Sampling: Since the water was a dirty brown color, we were almost sure we would find something wrong with the chemical balance. We tested pH and alkalinity, Nitrates and orthophosphates. Surprisingly, everything appeared to be normal based off of our
The hypothesis is if the organisms were exposed to pollution then they will act differently and scared in the habitat. For the experiment the independent variable was the pollution that was added into the habitat,and the dependent variable was the reactions of the organisms from the pollution by adding trash to the environment. For the experiment the things that were controlled were the amount of the water in the habitat. Also how clean the water stayed was controlled as well as how much food the organisms got. These things make a good control group because if they are not controlled then the organism could die. The things we kept the same was the amount of food, the habitat, the amount of frogs, the temperature,
The primary purpose of Experiment 22: An Analysis of Water Quality was to determine the quality of four different samples of water using multiple tests. During the experiment we tested to find the pH, nitrate, chloride, conductivity, alkalinity and hardness levels of all samples. Since all of these techniques have been previously used, the secondary purpose of this experiment was to review and combine these techniques. Knowing and understanding the purpose behind these testing practices allows us to apply them to real world situations.
This lab had various objectives, but they were all similar in that, the main purpose was to understand the effects of extra nutrients in water and how they affect the environment around them. Also another overarching objective of this experiment was to see how a spectrophotometer could be used as an indirect way to see if algae are present in various types of matter at 450 nm absorbance. Another purpose of this experiment was to find out that acidic rain is a type of a pollutant that leads to a decrease in aquatic organisms. The hypothesis that was thought of during the initial understanding of the experiment was that as the amount or concentration of nitrogen and phosphorous increases so will the growth of algal. The results that
In this experiment, the group was given two unknown solutions and were told to discover the pH of each solution and if the two unknown solutions could be neutralized. The question they were solving for was; “How do you determine whether two solutions are acids or bases and whether these two solutions will neutralize each other and change their pH level?” The hypothesis the group decided on was; “We predict that if the unknown solutions are acids they will turn the blue litmus paper red and if they are basic, they will turn the red litmus paper blue. We predict that one of the two unknown liquids will be acid and the other will be base, so if the two unknown solutions were put together, they will neutralize each other and have a pH around 7.” There was no other research done on this project.
The data collected and found while in the trip, can determine who polluted the water is. It was concluded that the water quality is good to excellent. The first graph shows the level of nitrates, phosphates and dissolved oxygen in the water. There was an average of 2.5 ppm of nitrate found, 1.7 ppm of phosphates, and 8.7 ppm of dissolved oxygen. Phosphates and nitrates are harmful to the water and can cause algae blooms, which then creates dead zones. These chemicals come from farms mostly, and run down through the soil, into the water. That is why areas with an abundance of agriculture can sometimes negatively affect their nearby water source. The dissolved oxygen level found was also good. Dissolved oxygen is the gaseous form of oxygen found in water. Without it, animals would not be able to survive underwater. Many factors affect how much dissolved oxygen is in the water, such as temperature, the atmosphere, water movement speed, and plant life in the water. The average temperature of the water was about 69 degrees Fahrenheit and about 20.5 degrees Celsius. Cooler water temperature creates more dissolved oxygen. With more dissolved oxygen, it is easier for animals to survive in the water. Another component of the water that was measured, was turbidity. Turbidity is how far down in the water you would be able to see with your naked eye. If water has a high level as turbidity, it would mean that you could see far down, and the water would be clearer. If it
