These curricular materials are intended to explain wastewater treatment processes, detail the goals of the Boston Harbor Project, and describe the responsibility of individual citizens to the revitalization of Boston Harbor. A series of student activities covers three main topics: wastewater operations, wastewater residuals, and household hazardous waste. Activities are written at a junior high school reading level but can also be adapted for older or younger groups. Each activity features an introduction for the teacher explaining the goals, concepts, materials, and procedures for conducting the lesson. (WRM)
