Ahh, yes, much nicer to look at. Notice, I made the rainwater a gradient blue colored bar just because there is no before or after for the rain. My results took me by surprise when I found not only that the rainwater contained the highest nutrient measurements of all the water samples, with the exception of HPSMP-2 site which I'll touch on momentarily. Also some sites experienced a decrease in nutrients after the rain despite the amount present in the rainwater I collected, while others experienced an increase. I have to look into why this is.
Now, I still have to work with the NOAA HYSPLIT computer model to see where the storm that brought the rain had developed and traveled over. This will help me determine a source for all the nutrients found. I collected a second sample of rainwater for comparison and while it contained less nutrients than the first sample, it still contained more nutrients than those found in the ponds so I plan to make a trajectory model for that storm as well.
Looking again at HPSMP-2, one can see that after rain, both levels of Total Nitrogen and Phosphorus had increased, the nitrogen levels dramatically. This may not be due to surface runoff associated with the storm though, I'm inclined to believe the results were of anthropogenic origin. Found at the HPSMP-2 site after the rain was this:

Still to come are my HYSPLIT models which are to be generated soon and an update will be made this Friday when I conclude my project and reflect on it.
Thanks for tuning in!
