My hypothosis for the WQI was correct because we redid the test and it came out good! We even tested the macroinvertebrates in the water. It determined if the water held the type of bugs that could stay in polluted water, in betweens, and if there are bugs that can live in only non-polluted water. We got them from all categories, which is good water.
We got the WQI by all our test averages, and the class' averages. Then we would go to the SITE books and look at graphs to determine the Q-value. After we got that, we could multiply the Q-value by the Weighting Factor. We would then have to add all the numbers together and then we would have a WQI!!!
Three things that I have learned to do during water quality testing is a lot of math!!! Also I have gotten to see some things that I have never seen before, like some microinvertebrats. I also learned how to test pH and total solids.
I don't really think that I would do anything different, except that
I would bring a coat out on the cold days!!!
