Creek feeder:
Average: 12.666ppm
Why are they different? The creek feeder’s Phosphate level is lower than the Rhododendron Creek’s ppm because the creek feeder does not flow into that part. Also, there are houses all around it which causes pollution. It is also in the middle of a park so lots of litter runs off into the creek feeder. There is also less life in that steam compared to the Rhododendron creek. All this affects this steams phosphate level.
Why are they similar? The Creek feeder and Rhododendron creek’s phosphate levels are somewhat similar. They both have very poor phosphate readings. This is because there is so much constructions, roads, litter, and people around both streams. It causes lots of unwanted nutrients to enter the creek and cause it to be unhealthy.
Before pipe:
Average: 15ppm
Why is it different? I think the Stream before the pipe is different from the creek feeder because it is not attached to the creek feeder and so it must be almost fully different. Also, the stream before the pipe has lots of constructions surrounding it, which causes high pollution and an unhealthy stream with unwanted nutrients. Too many nutrients cause lots of the aquatic life to die. There is also a lot of litter around the stream from runoff and the people who throw their trash in the stream. The Stream before pipe and after pipe is almost the same but the stream after the pipe also has the water from the creek feeder in it.
Why are they similar? The stream before the pipe and the stream after the pipe are very similar. The only difference is that the stream after the pipe also has the water from the creek feeder in it. This causes the quality of Rhododendron creek to be slightly mixed with the creek feeder water, but the water from the creek feeder flowing into Rhododendron creek is so little that it the ppm of the creek doesn’t change from the creek before pipe.
After pipe
Average: 15ppm
Why are they different? Rhododendron creek after the pipe is different from the creek feeder because the creek feeder mixes only slightly with the water from Rhododendron creek, causing the pph not to change. The stream after the pipe is different from the stream before the pipe because the stream after the pipe also has some water from the creek feeder. This does not change the ppm though.
Why are they similar? Rhododendron creek after the pipe is similar to the stream before the pipe because it has almost completely the same water. It is similar to the creek feeder because it has some of the water from the creek feeder in the stream after the pipe.
