On October 1 and 2 students in the AP Environmental Science class embarked on a field trip to
The Sioux River to conduct a series of water quality tests. The trip aimed to provide hands-on experience in assessing the health of aquatic ecosystems. Students tested various parameters, including ammonia, nitrites, nitrates and phosphates, which are key indicators of nutrient levels in the water. These nutrients can influence the growth of algae and other aquatic plants, potentially leading to eutrophication if present in high concentrations.
In addition to nutrient testing, the students measured dissolved oxygen levels, temperature, total coliform, pH, total dissolved solids (TDS), and turbidity. Dissolved oxygen is crucial for aquatic life, and its levels can indicate the overall health of the river ecosystem. The pH test helped determine the acidity or alkalinity of the water, while turbidity indicated the clarity of the water, affected by suspended particles. By testing these parameters, students gained an understanding of how various factors contribute to water quality and the health of aquatic environments.
