The cumulative result of almost 100 years of mining, milling, and smelting of zinc and lead has had significant and negative ecological impacts on portions of Jasper County, Missouri. The site was listed on the National Priorities List in 1990. The USEPA has developed a Proposed Plan for the ecological impact with 6 remediation alternatives. This case study presents the background information on the site and the 6 alternatives, the USEPA preferred alternative, a USEPA fact sheet, and examples of local media coverage. In the classroom, the case is presented as though the students are the Jasper County Superfund Site Coalition, a citizens group who must assimilate the information and provide meaningful input to the USEPA during the public comment period for the Proposed Plan and the Record of Decision. The instructor can act as either a technical advisor or chairperson for the Coalition although ideally a student would serve as chairperson and the instructor would be the technical advisor. The case can be used to introduce students to the concepts of ecological risk, human health risk, soil and water chemistry, soil remediation, the Superfund process, and the social and political issues that are delicately entwined regarding this site. Class discussion can be directed toward a poll with the purpose of determining the alternative with the greatest support from the Coalition. Writing and problem solving exercises can also be easily developed from the materials.
