A fictional town, where every home and most businesses have a private well, has discovered that the groundwater is contaminated with some kind of fuel. Possible sources of the fuel spill include the Heating Oil Company, the Trucking Company, or the Gas Station. Students will play detective and determine where the pollutant is coming from. Since cleaning up groundwater contamination is a very expensive job, students should be very sure of the location to start the clean up. It is up to the students to solve the mystery. Students will make a topographic map, use it to predict groundwater flow and investigate the most likely source of groundwater contamination. Using a map of the town and the contaminated wells, students will collect data and answer questions about the flow of groundwater and pollutants. While no expectation of time is given on the lesson, this may take one, 45-minute class period.
