Through a variety of activities and cooperative learning strategies, the students explore the causes, effects and sources of water pollution in the world and in North America. Students also use hands-on activities to simulate water pollution and water filtration scenarios.
Even wastewater that has been treated often contains high levels of biological contaminants, phosphates, nitrates and even some medications. Before treated wastewater can be released back into a water source, it has to meet certain guidelines regarding quality and level of contaminants. But accidents can happen and wastewater can be released without being treated at all.
