Today I met with Mr. Schwinnen and Mrs. Laughbaum at the high school in order to perform chemical testing on my water samples. Mr. Schwinnen taught me how to use the YSI 9300 Photometer to find the phosphorus and nitrogen levels. For both tests, I filled a test tube with my water sample of a site, and then I put a crushed tablet that goes with whichever test I was doing (nitrogen or phosphorus). After that dissolved, I put the a second crushed tablet into the sample and let that sit for 15 minutes. The two tablets are labeled so I know when to use each one. While the test tube was sitting, the water would change colors. Once the 15 minutes were up, I put the sample into the YSI 9300 Photometer so it could give me the nitrogen and phosphorus levels. I repeated these steps for all 5 sites with the nitrogen tablets and phosphorus tablets. After I wrote down all my results, Mr. Schwinnen showed me the HI 93703 and I found the turbidity. All I had to do was shake all my water samples and put them into test tubes. These test tubes then went into …show more content…
Most importantly, I learned how to use the YSI 9300 Photometer and HI 93703. They were pretty easy to figure out except that I had to put a control sample into the machine first. So, for the YSI 9300 Photometer the original water sample must be put in before the one with all the tablets dissolved. Also for the HI 93703, a test tube of distilled water would be put in before the water samples. I also forgot to put a turbidity spot on my data sheet so I am going to have to revise the data sheet again. Lastly I need to figure out what all of these chemical aspects mean concerning stream health. This means I am going to do a lot of research moving forward. I am planning on reading a lot of research papers by other scientists and looking on reliable environmental science websites. After today, I learned what to expect next time I do chemical
In this next stage we’re doing the Eutrophication Test, which is a test that finds the phosphate, nitrate, and dissolved oxygen. After everybody did their test, we all gathered and compared our results. My group did the phosphate test and got 0 ppm, and the everybody got an average of phosphate of .l ppm. Then the average for nitrate was .9 ppm. Last the average we all calculated for dissolved oxygen was 9.8 ppm.
Mr. Bodly was in charge of this station. What we had to go is, we had to get a kit, inside the kit we did to feel up the small bottle that was in the up up to 25 glm. ( some of the groups filed their small bottle up with either something more than 25 glm or smaller than 25 glm and they also had a different kit than others, some had the same, some didn't ) After we did that we put the amulet inside the water and broke the tip inside the small bottle. Once we did that we had to let the ampulet sit for a little. So after that we let the ampulet sit for about 2 minutes. If the ampulet changed a color then that means that the water was polluted. That being said if it didn't change a different color it wasn't polluted. So the kit we had did not turn a different color, meaning the water was not polluted. After every one collected the data within in the kits, Mr. Bodly collected the ampulets to look at the colors that were made and saw some that didn't change at all, which one of those were my groups
19. Stir the solution with a toothpick and observe any changes. Measure the pH of the new solution and record into Table 2.
I have learnt many new ways of gaining data and how to use many chemicals and metres to determine the results. This assignment has also gave me a look at how the council manages its time to make the creek cleaner.
Please briefly describe the different types of water pollution mentioned throughout the "Poisoned Waters" video. Fertilizers, Nitrogen and Phosphorous caused algae which poisoned the waters. It caused a dead zone. The farmers who own chickens was allowing the manure to pollute the water. The humans race is all responsible as we pollute our water by throwing garbage into it. Soap, household cleaning agents, toothpaste, and other plastic, lubricant and fuels are all poisoning our water.
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
Chambers is working to develop a proprietary blend of PHA and other chemicals that will be spun into the fibrous mat for testing in Crim Dell this coming summer. Once the mat is created, it will be placed at the groundwater inlet to the sedimentation basin, where nitrate-rich water discharges into Crim Dell. I will set up automated water samplers upstream and downstream of the PHA mat, which will collect water continuously at pre-set time intervals. These water samples will be collected each week for analysis at the Keck Lab for nitrate, ammonium, and dissolved phosphate using standard spectrophotometric methods. I expect to show that dissolved nitrogen and phosphorus are removed from the water column prior to discharge into Crim Dell, thereby improving water
1. Describe where your water sample was collected, and what the water environment looks like—what organisms live in the water your sample was collected from? Are there any known pollutants or chemicals that you suspect may be in your sample? (2 points)
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
“Where am I? What’s happening?” I thought to myself. “What’s going on?” It was late summer, and I was just coming out of my egg. After I hatched, I looked around in awe as I saw the world for the first time. I saw the bright green seaweed I was surrounded by. I saw the scintillating water as it was warmed by the sun. I saw various schools of fish swim
Around 70% of the world is covered in water, and over time water tends to change. Oxygen levels can rise, temperatures may decrease, and different environmental changes may be introduced. Naturally, water stands to be at a pH level of 7, that being neutral in acidity. However, due to the changes in water over time it seems, that too is changing over time. Even more so changes come from multiple sources outside of the environment, this includes cities and agricultural lands. In fact, a small percentage of water bodies are near agricultural areas, which also may influence a change in the water, with the introduction of nitrates and phosphates, from agricultural runoffs. Nitrates and phosphates are known to have high oxygen levels, which will affect bodies of water further. On an ecological scale, such changes put the aquatic inhabitants in danger. With this being known groups of scientist went to investigate the changes in water bodies by measuring the nitrate and phosphate levels in comparison to the dissolved oxygen levels, as well as the pH, temperature, and turbidity to see if any real significant changes have occurred.
The purpose of this lab is to determine whether a liquid is hard water or not.
One of the most common problems with the presence of excess water in communities, whether via tropical storms or coastal flooding, is where the water goes and what is in that water.
Surface and groundwater quality concerns apply to both drinking and recreational waters. I being an avid outdoors man and scuba diver have come to respect our nation’s waterways. Thus, contamination by infectious agents or chemicals is contradictive to public health. In my practicum I had the opportunity to test water for contaminants and protect natural water areas in order to protect water sources and prevent illness related
The PH test is a simple test which tests the PH level of the stream. Dip the strip, check the colors, and figure out what the PH level is. Around 6-7 is good. The second test is the nitrate test. When you order the appropriate kit for this nitrate test, and follow the instructions that come with that kit. If you can’t afford the kits, or it will take too long to ship, there is another test that you can perform. The name of this test is an acronym call SOSMART. First check how the water smells, which is the first S. If it smells quite odd, this can be a sign that the stream is polluted. After that, check if there is any Obstruction, what the Stream bed is like, the Margin, the Appearance of the stream, then Rate the stream and look at what is on the Top layer of water. If the stream is found to be polluted, it is a good idea to contact the government and inform them.
