Water pollution—Wells

A pioneering late 19th-century examination of the hidden dangers lurking beneath the surface of everyday water supplies. Irving A. Watson, writing during an era when the germ theory of disease was still revolutionary, systematically documents the ways in which wells became vectors for deadly contamination. Through careful analysis of water sources and their relationship to outbreaks of typhoid, cholera, and other waterborne illnesses, Watson argues that the seemingly pure water drawn from rural and suburban wells often carried invisible threats. The book reads as both scientific treatise and public health plea, urging readers to understand that what lies underground cannot be seen but can absolutely kill. For modern readers, it offers a fascinating window into the birth of environmental health science, when researchers were first connecting the dots between contaminated water and human suffering.
