Answer:

Spatially associated with certain public water pumps.

Explanation:

Dr. John Snow was a Physician and regarded as the father of epidemiology.

During the cholera outbreak in the 1800s which killed thousands of people in the United Kingdom , he traced the source of the outbreak.

Before then cholera was believed to be an airborne disease but he refuted this and helped in discovering that the source of the outbreak was as a result of certain public pumps. He then urged the council to disable the pumps and this helped in solving the cholera outbreak problem.
