Have you ever wondered what’s in the rivers you swim in? What the water quality of the river is? Well, my science class went to Oxford Pond and the Coquitlam River to find out what invertebrates are in the water. Invertebrates are creatures with no backbone. At these two water bodies, my class took water samples and analyzed them. They then gave the results to me because I am not physically attending school right now and I didn’t have the tools to analyze it myself. I learned about the water quality in the pond and river. The Coquitlam River’s approximate water quality index was 86 as seen in the chart, this indicates that the water quality is good. This also means the water quality supports a high diversity of life and is suitable for all forms of recreation including contact with the water. The Oxford Pond approximate water quality index was 78 in the chart. That means the water quality is good and just like in the Coquitlam River, it has a high diversity of life in the pond. In the water at the Coquitlam River, the invertebrates found were 8 mayfly nymphs and 2 worms. There were also 2 salmon fry and 2 tadpoles. In the Oxford Pond,  the invertebrates found were 1 mayfly nymph, 1 dragonfly nymph, 4 gilled snails and 1 riffle beetle larvae. Both the Coquitlam River and the Oxford pond are good water quality the only thing different was more invertebrates live in the Oxford pond.
