We are completed this investigation because we are doing the PULCHRA challenge to help regenerate urban space to connect people in a healthy environment. Within the PULCHRA challenge we specifically looked at water pollution and the quality of water. We expected to find a neutral PM and a range of organisms.
Our hypothesis is to examine the water of our local stream to see if the water is of a good, moderate, or poor standard. We expect the results to be poor to moderate.
