Topics Explored: Point and Non-Point Source of Pollution, Human Impact on Aquatic Ecosystems, Sewage Treatment, Human Pathogens

This case study explores the historic event of the Great Stink in 1858 where raw sewage polluted the River Thames and created an environmental and human health crisis. From this we describe in detail modern day wastewater management methods.  Answer key included.
