Water Quality Study

Water Quality Study

In our studies we went to the oxbow pond in Port Coquitlam. The pond is located on the Poco trail. On day one we had to go into the pond and catch invertebrates. We analyzed what we caught to discover what was living in the pond. We had two SFU students come in and teach us how to find water quality the next day. Each group was given something to focus on. I got turbidity and we had to test that on Wednesday in the pond. After we were done in the pond we went to the river to catch invertebers. We did not test the water quality in the river.

 

Water quality

 

Our class tested the quality in the oxford pond behind our school. The other science class tested in the river. The final numbers for water quality are, oxford pond: 82.24 and Coquitlam River 89.43. they are both in the good category. the subjects we tested were turbidity, nitrate, phosphate, temperature, dissolved oxygen, ph., and dissolved salts. Good means there is a small amount of amount of impairment, high diversity of life.

Turbidity

Turbidites test was very simple but one of the ones that had the most amount of having to estimate. Turbidity is a special word for murkiness. How clear the water is? In this test you have sample water and water from the tap or distilled. You add reagent drops into the distilled water. Those drops make the distilled water murky. The tubes you have the water in have a black dot at the bottom that you must look at. You must add more reagent until they are equal.

Invertebrates

I was not there to catch them in the pond but when we went to get them in the river our group caught one. The bug we caught was the same as almost every group that caught something. The bug was trying to hide under the grass that was in the grass. It was called a Dobson Fly.
