Acri Meadows Park Experiment

So we can conclude that the creek is not polluted based on this evidence. The creek creature are mostly from group 1 and 2. Also, the creek water contains little to no nitrates and phosphates. The creek also contains a high amount of dissolved oxygen (9.8ppm to be exact) Lastly, the creek limestone neutralize acid rain. The pH of the water is also a healthy 7. After all this evidence we can conclude that the creek is not

At the first station I was at, we were looking for macroinvertebrates and crustaceans. When we found one of the insects we had to determine which group they belonged in. One way to determine if the water is polluted is to look at which group the critters are mostly from. My group and I tested this by taking turns going into the creek and finding a rock to bring out. When we brought the rock out of the water and back to our group we had to make sure to turn the rock over because the critters normally live on the bottoms of the rocks and most likely would fall off if you didn’t turn it over. After we all took turns a couple of times

“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

On October 8th, 2015 our 8-Orange team took a field trip to the Conodoguinet Creek to test the water quality. The Conodoguinet Creek was tested about 2 different times. It was tested about 2 times to take a test to see if the water was polluted or unpolluted. The results will help you understand the conflict of the Conodoguinet Creek.The water came up to about our knees. This trip was different but very informational.

Silvershell Beach is the home to many different aquatic species and other forms of wildlife. Last lab block the class and I went into the ocean at Silvershell beach and took seven different seine net samples. With each sample we took, we noticed a variety of different organisms. As we moved around different areas of the ocean, we would come out with changing species and number of species that we did not find in other areas of the water. Species we found included sea robin, hermit crabs, moon jellies, minnows, shrimp, eels, and more. Sample one and two were taken from around the same area in the water and there was a reappearance of three of the species. In sample one we found hermit crabs, minnows, moon jellies, and a sea robin. In sample two

Each person got to test either the phosphates, nitrates, dissolved oxygen, or the ph in the creek. Phosphates and nitrates are nutrients found in water due to fertilizers, decaying plants and bacteria. Dissolved oxygen is the amount of gaseous oxygen dissolved in the water. As we recorded our results, we discovered that the dissolved oxygen levels were very high, which is good because the higher amount of dissolved oxygen in the water, the healthier the creek is. The phosphates levels in the creek were all perfect zeros, which is great because having nutrients in the creek is not healthy. The nitrate levels were slightly higher, at 0.9. That is not bad at all, but it isn’t perfect, showing signs of pollution. The ph levels in the rocks were neutral, right at seven. If they were lower than 7, that would mean they have acids in them, and if they were higher than 7, they would have alkaline in them. Alkaline, or bases, neutralizes acids. The number of rocks that we found that neutralized acid was 65, and the number of rocks that did not neutralize acids were 29. This shows that about one-third of the rocks in the creek do not neutralize acids.

On October 6th 2015, the students of Mattawan’s AP Environmental class took a trip to the local stream of the Mattawan Consolidated Schools area. The purpose of this trip was to conduct a stream study to determine the health, conditions, and pollution levels of this small body of water. A multitude of factors came into play when making a judgement on the stream’s health, and making sure to take all of these essential points was crucial to the study. A variety of thorough experiments were conducted to help make this overlying conclusion, as many students adopted many roles in the study. Students used a physical survey form, water test data sheet, and taxa recording sheet to record their findings. Teamwork was essential in making sure all of this information could be found accurately and efficiently. The combination of all of the final results allowed the class to make a judgement of the stream’s state.

This is a map of the Conodoguinet Creek, where the 8-Orange team of East Pennsboro Middle School went yesterday to study the creek. The 8-Orange team, including myself was studying to see if the Conodoguinet Creek had any type of pollution. The reasons for us going down to the creek to test is the problems we have in Central, Pa. Some problems are the acid rain coming from the Power Plants down the road, and sometimes from Pittsburg, Pa also. Theres many more problems but these are the two main ones. We all split up into three groups which were, finding the velocity of the surface water, identifying the different critters there are in the creek, and testing the water for (phosphate, nitrate, and dissolved oxygen). It was incredible we all got different amounts of data.

Either or both of those two things could have runoff from the land and drained into the creek. They are negative to the creek. Our results showed that the creek was containing little to no phosphate. The average number after 15 tests was just 0.3- zero being the best. Similarly, nitrate is a salt or ester, but it is made of nitric acid, containing the anion NO3. It is found in runoff from fertilized farms and treatment plants. The same process was used for testing nitrate levels. The average level out of eight tests was 0.8, which is a higher than phosphate but still relatively low. Both of those test results were very positive. It showed that the creek was low in eutrophication. Another chemical test is testing for dissolved oxygen. Dissolved oxygen is microscopic bubbles of oxygen (O2) that are in the water and there for aquatic organisms to breathe in, which is necessary for almost all organisms. The testing process was similar to that of nitrate and phosphate tests. After testing the water, we got an average level of 11.4. More dissolved oxygen allows for more gaseous bubbles for organisms to breathe in. Therefore, a higher number is better. Twelve is the highest level of dissolved oxygen possible. Thus, since 11.4 is very close to 12, the dissolved oxygen level was very good. Dissolved oxygen can be changed in a number of ways. First, stagnant, or not moving, water has a much lower level of dissolved oxygen. Also, hotter water has less dissolved water. Lastly, chemicals like phosphate and nitrate can cause the growth of algae (which will be discussed in more detail in paragraph three), taking away oxygen. Additionally, the students tested for acid rain pollution. The tests falling under the acid rain category would test for acidity or alkalinity in water. We took a pH test, which is a level expressing the

Is the Conodoguinet creek polluted? I thought it was, but multiple tests from my peers and I proved my hypothesis wrong. To prove our hypotheses, my peers and I did multiple tests of the organisms living in the creek. We also tested the water quality. You may be wondering, “ How does this apply to me?” “ Why should I care?”, the fact is that the Conodoguinet runs through 100 miles of Pennsylvania. It runs through farms, towns, communities, and maybe even your backyard. So, making sure we protect it should concern all of us.

At this station, we tested the creek water for phosphates, nitrates, and dissolved oxygen. What we found for phosphates was an average of 0.3 phosphates. For nitrates, we found an average of 0.8 nitrates. For the dissolved oxygen, we got an average of 11.4. This shows that the Conodoguinet Creek is pretty healthy. We also tested for acidity and alkalinity. To do this, we needed to use a pH scale. A pH scale goes from 0 (acidic) to 14 (alkaline). A good place for the water to be is 7, this means that the water is not acidic, nor has alkaline in it, but it is neutral. The water in the Conodoguinet Creek was at 7, so it was

Let’s start out with the pollutants in this water. There was a surprising amount of pollution found downriver of Sioux Falls, the largest city in South Dakota. It makes sense that more pollutants would be coming from more heavily populated areas, but it doesn’t change the fact that it is harming all those around it. It is thought that a lot of this pollution is coming from the city waste

The water levels were good enough for animals. The temperature were average for when I went out. The PH levels were good enough for the “Mouth Average”. The Con. were high good enough to make energy. The salinity was average good for saltwater. There was DO in the water was the right amount. The DCO2 were low. There were also low N and P and Sulfide. Alkalinity was average. The Turbidity were a bit higher than

Polluted water will mean that your clean up and restoration process may be more extensive and you may need to dispose of certain belongings in your home if they’re damaged by the contaminated water.

Included in the report are various organic and inorganic chemicals that may or may not be naturally occurring, amounts found, and where the chemicals are thought to be originating from. Like every city in the United States there is going to be elements and chemicals that are found that will scare some people. But the important thing to look at is the part per amount in the water. The water reports normally list every compound found in the water, as well as non-regulated compounds found. This is great because they do not discriminate on which compounds to list. After they receive the list, they then measure the amount usually parts million (ppm) or parts per billion (ppb). The Environmental Protection Agency has done extensive testing and found safe cutoff levels of these chemicals and in order for a city to produce drinking or potable water, they must adhere to these
