Monitoring water quality for detection of pollutants or unsafe levels of certain elements using pH, temperature, and dissolved oxygen testing. The following activity is a simulation for monitoring water quality. The tests used in this lab are the same as those used by refineries to test water quality for residuals from the refining process or dredge materials and is also used by fish hatcheries to ensure optimal growing conditions for young fish.
Many factors play a role in water quality including runoff, acid rain, heat, and chemical reactions.
The techniques used in this simulation are used throughout industry and environment entities. This activity is best done in cooperative groups of three to four students. Water samples for groups should ideally come from different areas around your community. Contact Texas Parks and Wildlife for sample locations. Finally, a good prelab should be used to assess prior knowledge.
