This is an answer I had in mind myself. Has anyone studied history and knows the historical facts concerning the Roman aqueduct systems, source of the water, purity, etc...

Here's a little history of one that's even [indirectly] mentioned by Christ:
1 Now there were some present at that very season who told him of the Galilaeans,
whose blood Pilate had mingled with their sacrifices.
3 I tell you, Nay: but, except ye repent, ye shall all
in like manner perish.
You know Pilate didn't 'mingle their blood' himself , he sent soldiers to do the deed. 'In like manner' they were all to die if they did not repent.
4 Or those eighteen, upon whom
the tower in Siloam fell, and killed them, think ye that they were offenders above all the men that dwell in Jerusalem?
5 I tell you, Nay: but, except ye repent, ye shall all
likewise perish.
Josephus most likely recorded this event that happened in the 'berg' of Siloam. Roman soldiers, again by Pilate's orders, disguised themselves and mingled with the crowd and fell upon them with clubs and beat them to death to quell a disturbance among the Jews over
Pilate misappropriating temple funds to extend an aqueduct from the spring at Siloam. They were all to 'likewise' perish if they did not repent.
“After this he [Pilate] raised another disturbance, by
expending that sacred treasure which is called Corban (10) upon aqueducts, whereby he brought water from the distance of four hundred furlongs. At this the multitude had indignation; and when Pilate was come to Jerusalem, they came about his tribunal, and made a clamor at it. Now when he was apprized aforehand of this disturbance, he mixed his own soldiers in their armor with the multitude, and ordered them to conceal themselves under the habits of private men, and not indeed to use their swords, but with their staves to beat those that made the clamor. He then gave the signal from his tribunal [to do as he had bidden them]. Now the Jews were so sadly beaten, that many of them perished by the stripes they received, and many of them perished as trodden to death by themselves; by which means the multitude was astonished at the calamity of those that were slain, and held their peace. “ Josephus, Wars of the Jews, Book 2.9.4
