For each test, students learned the impact of that feature on wildlife and the environment. Higher levels of dissolved oxygen, for example, support more diverse species and a healthier ecosystem. Low levels can weaken or kill fish and other aquatic life. The brook's pH, 8, fell between the favorable range of 6.5 and 8.5. There were high levels of dissolved oxygen and the water had perfect clarity. A temperature of 13 degrees Celsius was recorded. The students learned that cooler water holds more oxygen.
As a registered site for the study, the students entered the data into an online computer database being used to collect sample information from around the globe. Students were able to compare their results to those in various regions. For the Fayston and global results, visit www.worldwatermonitoringday.org .
World Water Monitoring Day is a program of the Water Environment Federation (WEF) and the International Water Association (IWA). The goal is to increase public awareness and involvement in the protection of water quality around the world.
