Water Quality Testing/Inverdebrate Sampling

Introduction:

Last week during science we went outside to the Oxbow pond located on the Port Coquitlam trail, to test the water quality and find different invertebrate samplings. Each group was given a compound to test out during our time in the pond. The next day we headed out to the Coquitlam river to find invertebrate samplings.

Water Quality:
The compound that my group tested was nitrate, and the result that we got was 1.0 mg/L NO3. The overall water quality index value for the Oxbow pond is 82.24, and the water quality index value for the Coquitlam river is 89.43. These values tell us that the health of our pond is very good. This means that our pond is not harmful to any species around it, and is safe to be used from.

Invertebrates:
The various kinds of invertebrates that my group found in the Oxbow pond is the Dobsonfly and a fish. None of the other groups got what we got in the Oxbow pond. In the Coquitlam river we unfortunately only got one invertebrate, called the stonefly. Only one other group got the same invertebrate as my group. The sampling results at the two different sites don’t really compare because they aren’t the same invertebrate. But both the pond and the river have living invertebrates in them.

Water Quality/ Invertebrates:
The water quality in the Oxbow pond and the Coquitlam river is excellent, according to our overall water quality index values. This leads to a lot of invertebrates living In the water.

Reflection:
Going outside and doing these activities really helped me understand water qualities and invertebrates a lot better. I really liked being able to experience what a scientist actually does on a daily basis. Working in groups also helped me because, I was learning and having fun with friends at the same time.
