We have a water fountain whose filter mechanism includes a power cord that runs through the water reservoir. The instructions include a warning that the cord contains lead, and that we should wash our hands after touching it. So if the cord is actually sitting in the water, does this lead get into the water at all? Is it safe (for humans & animals) to drink?
The presence of a toxic substance does not automatically imply a risk. It all depends on the dose. The amount of lead that would potentially leach out into the water is too trivial to be an issue. However if you are concerned, avoid making use of this water given that there are many other sources available.
