After a 4 year study, it appears that many individuals in Walkerton who had reported liver problems, developped the ailment not because of the ecoli bacteria found in the water BUT due to drinking too much water!

The study goes on to say that they don't know exactly how much water an individual must consume in order for it to equal too much water.

So in light of the last revelation, scientists may admit that drinking some water infected with ecoli is in fact drinking too much water.
