Cholera and the Water Supply in the South Districts of London in 1854

In this pioneering study, the author examines the 1854 cholera outbreak in London's south districts, arguing that the disease spreads through contaminated water rather than airborne miasma. Drawing on detailed observations from cramped households, mining pits, and two local outbreaks, he shows how waste from infected patients could infiltrate the town's drinking supply. The narrative blends careful fieldwork with early microbiological reasoning, laying a foundation for modern public health.

The author maps the water distribution network, pinpointing the sections of the Thames that carried sewage into the Lambeth Water Company's lines, and contrasts them with a newer source at Thames Ditton that proved safer. He records the striking drop in mortality after the switch to cleaner water, providing compelling evidence for a causal link. Readers gain an insightful glimpse into the birth of epidemiological mapping and the relentless pursuit of data that reshaped how societies tackle infectious disease.
