In order to create different trend lines on my Water Quality graph, I decided to include a very common type of water found in the household, tap water! I felt that it was important to include such a common type of water so that everyone can compare the other types of water to one we all know of use and regularly.
To remind you of the variables that will be compared to this week's sample results on a graph, I've included the test results from last week's water quality test on rain water below:
Turbidity: 0 JTU
pH: 7
Dissolved Oxygen: 2 ppm
Nitrate: 3 ppm
Phosphate: 0.5
This week, since I used water from inside, I do not have weather conditions. The test results for the tap water sample are as listed and pictured below:
Turbidity: 0 JTU
pH: 7
Dissolved Oxygen: 1 ppm
Nitrate: 4 ppm
Phosphate: 0.5
 |
| 0 JTU turbidity |
 |
| 4 ppm Nitrate |
 |
| pH of 7 |
 |
| Dissolved Oxygen 1 ppm |
 |
| 0.5 Phosphate |
| My Proposed Graph for Water Quality Testing
By looking at the graph, it is clear that so far the two samples chosen have similar test results, especially for both turbidity and phosphate. I am interested to add in salt water from my favorite surf spot to see how that sample relates to these two.
Respectfully,
