For this first 6 weeks my passion project was on water pollution. There are many different forms of water pollution but I chose Agricultural Runoff. I chose this particular form of pollution because in my past couple of times fishing in one of my local ponds I noticed that there was a build up of algae growth.
It seemed that every time I casted, I reeled in about 10 pounds of the algae. So when I had to decide on an issue I wanted to fix, I decided on this. I researched what causes excess algae growth and learned that when it rains, fertilizers can be swept up in the runoff and be deposited into waterways.
This introduces chemicals that can encourage excess algae growth. In can result in ponds looking like this.

This is an example of an algal bloom or algae bloom. When algae grows over the surface like this it can block sunlight out from the fish and plants that grow underwater.
So I decided to do something about it. My driving question is, “How can I experiment and figure out a way to limit agricultural runoff effects in freshwater areas of water?”.
My plan on how I am going to accomplish this is through an experiment. In my research I came across several sources that talked about how activated charcoal can “soak up” some of the chemicals found in fertilizers.
I am going to conduct several experiments on the water from 2 local ponds. I collected one sample of water for a base test by not altering the water in any way. I called this Test #1. I sent the water to the Pitt County Ag Center where they are currently testing to find the different amounts of chemicals in the water. I will then use activated charcoal to see what levels go up and what levels go down. I called this Test #2.
After Test #2 I am going to introduce fertilizers to the water and then add activated charcoal to see if the chemicals can be soaked up. I’ll call this Test #3. One of the big obstacles I am facing is that it takes 2 weeks for the water to be tested and for the results to get back. For that reason I am not going to meet my SMART goal this six weeks and am going to change it so that I present my plan this six weeks and I can experiment in the next six weeks.
Thanks for reading about the intro to my Passion Project.
