> The whole antisemitic conspiracy theory of Jews poisoning the well only works if people were actually drinking from the well.

Not really. Independent of people drinking directly from the well:

* animals are watered by getting the water from the well.

* food is prepared with water from the well

* ale is prepared with water from the well

and so on. All of these things would subsequently be poisoned if the well was poisoned. They needed a safe source of water, but that does not imply that they drank it directly.
