He did further research and found the polluted water from pump was {#blank#}8{#/blank#}(blame). He immediately told the astonished people not to drink the water. Later, John found supporting evidence from two other deaths linked to the Broad Street outbreak. So, he was able to announce with {#blank#}9{#/blank#}(certain) that cholera was spread by germs.
