We checked water quality to determine whether the water is harmful to animals living in the body of water. We tested for turbitiy, which was the cloudiness or haziness in the water - kind of like smoke in the air. This can mess with the fish's gills and kill them. We tested it using a secchi disk. We tested for the salinity, the salt effects how light refracts or bends in the water. We measured the salinity using a refractometer. We tested for the pH levels, which is its concentration of hydrogen ions. We used a litmus paper, which is different colors, on a scale from one to seven, negative and positive. We used it to test the acidity, and how clean the water is.
