Hello,
Barbara and I's conclusion is as we thought. The nitrates levels are very high in this area because we are in farm land. We tested the tributaries to the Sesquehanna (Little Conestoga Creek and Conestoga). We found the most Nitrates in the smallest stream we tested (The Little Conestoga), and then less in The Conestoga, and even less in the Sesquehanna because it keeps getting diluted. There is a very big push for buffer zones in our area by the Chesapeake Bay Foundation because our farm land is polluting the Chesapeake bay. Other than nitrates everything in our area was normal. We both had fun in the project and hope you did too!
