Every day, cities produce vast volumes of wastewater, and within that flow lies an unexpected record of public health and daily life. This book examines the growing science of wastewater based epidemiology, showing how sewage samples can reveal patterns of disease, drug use, and community wellbeing before other data sources catch up. You will learn how researchers collect and analyze wastewater, what biomarkers and pathogens can be detected, and how cities have used this information during outbreaks and beyond. The book also considers the practical challenges and ethical questions that come with monitoring a shared resource. Generated with the help of artificial intelligence and reviewed for accuracy, this book offers a clear, factual introduction to a field that connects environmental science, public health, and urban infrastructure.
