Holly Monroe(UR)- Saved Four Today

Update:
I do not have a graph just yet of my collected data. I will post a graph as soon as I collect the data and will explain each test individually in a short response paragraph. I will also include one scientific interpretation for the graph as a whole. I also had my original date for the BOD test wrong. The test will be ready for viewing tomorrow, so it will be included in tomorrows water quality update. I will also start a second BOD test tomorrow. However, for the graph mentioned previously, I will not be including BOD on it, nor any salinity. I am going to give them their own separate graphs. I also still need to get distilled water to preform the test (will have different testing dates).

Fourth day of water quality testing:
Time:

• Start Time: 2:20pm
• End Time: 3:00pm
• I preformed the tests inside again today due to the weather.
• All samples were collected at 2:20pm on 4-16-20.

Weather conditions:

• Air Temperature: 66 degrees Fahrenheit.
• Winds: NNE 15 
• Cloudy
• 20% chance of rain
• Was drizzling for about 5 minutes before I went out to test.
• 
  

  

  Cloudy Drizzle 4-16-20

  
  

  

  Rain Drainage 4-16-20

The road drainage can pose many pollution issues, which could have been what affected my results today. I know if I tested salinity today that would have also been off due to todays rain. I hope I am able to get the distilled water from the store soon to accurately test salinity so that a day like today does not pass me by again.
Results:

• Turbidity: 40JTU
• pH: Approximately 7.5
• Nitrate: Approximately 3ppm
• Phosphate: Approximately 0.5
• Dissolved Oxygen: 4ppm *I compared it to a BOD test by mistake, but it is the same color scale and does not effect the outcome.*
• 
  

  

  Actually Dissolved Oxygen Test 4ppm

  
  

  

  Nitrate Approximately 3ppm

  
  

  

  Phosphate Approximately 0.5

  
  

  

  pH Approximately 7.5

  
  

  

  Turbidity 40JTU

Correlation(s)/ Difference(s):

• Turbidity has been the same for the past few days.
• pH has a point 0.5 difference.
• Dissolved Oxygen has constantly gotten lower.
• Nitrate is the same as 4-15-20.
• Phosphate is the lowest it has been at 0.5.
• Still unsure how the levels are that low with so much plant and algae growth.
