A poorly designed latrine is located upstream of a surface drinking water source. Two cubic meters of stormwater contaminated by the latrine and containing 1010 MPN/100ml of salmonella flow into a shallow pool for collecting drinking water. The total volume of the drinking water pool after the contaminated water flows into it is 5 cubic meters. If the typical infectious dose for salmonella in this community if 100 organisms, how much water would someone have to drink to become ill due to the salmonella contamination?

What will be an ideal response?
