Dear Ron,
	As a matter of fact it was. In 1849, an English physician named John
Snow traced the source of an outbreak of cholera in London to a 
contaminated water pump.  He had the handle removed, and the disease went 
into decline. I think that case is mentioned in the film I previously 
described, but I'll have to dig it up and look. Good memory!
