Although the study of public health is just over a century old, many fundamental practices within it have roots in the earliest human civilizations. These include ensuring access to clean water, managing sewage, and safeguarding the food supply. Together, these endeavors form the basis of sanitation whose tools encompass the application of technological and engineering solutions to uphold public well-being. Through a series of readings and group discussions, this course will trace the history of public health sanitation and examine the relevance of sanitary practice in the context of modern challenges. The topics we will be covering include: drinking water, wastewater, solid waste, and agricultural systems.
