Supplied water from the thames river in the heart of

supplied water from the Thames River in the heart of London which was heavily contaminated with
cholera vs. the Lambeth Company which obtained water from the river at a point above the city and was
relatively free of contamination. - He removed the handle from a contaminated water supply pump
which reduced the cases of cholera in London. - His work led to changes in the water and waste systems
of London and other cities which significantly improved the general public health by reducing the spread
of disease.
