Problems
When testing for the turbidity i was getting extremely high readings. These results were counteracting my hypothesis that the turbidity of the water would be lower due to less movement in water. This test was done numerous time with the same samples with each result still being high. However the minor bubbles in the top of the water storage container which was placed in the turbidimeter completely threw out results. I had to re-do all my samples ensuring that i filled each container/flask to the complete top so there was no air between the lid and the container.
