Water Chemistry and Macros

Today our group went to the creek upstream from the dam. We tested two samples of the water to measure the pH, dissolved oxygen, alkalinity, etc. After we finished the testing, we kick-netted. We used nets attached to pole to catch aquatic macro invertebrates and studied them to determine the ones who had pollution tolerance and who were intolerant. We were able to do this by counting how many of a species was in a sample.
