Students in  Environmental Science have been studying water pollution. To help them visualize the potential contamination of groundwater, they constructed mini groundwater models. The models featured confined aquifers, wells, and both point and non-point pollution sources. Models showed the movement of simulated pollution in the form of two colored dyes to determine under what conditions contamination occurs from a variety of sources such as spills, farms, and buried tanks. Water was withdrawn from the wells to show how polluted groundwater eventually reaches the drinking water supply.


Working in teams, students also designed and built their own water filtration devices using ordinary materials brought from home. The filters were tested with muddy water and the effectiveness of their design was determined by the results of their filtered water. The hands-on experience gave the students a deeper understanding of the processes needed to ensure they have clean water each day.
