If so, then it could contaminate a water well in close proximity to the pond?
The BTI Briquets/dunks will not normally migrate anywhere it will simply slowly breakdown until gone in standing water areas where you dont want pest reproduction to occur. If any of the product did get into the water table somehow it would not be a problem as this product does not harm us and can be used in drinking troughs for animals, in ponds with fish being caught for consumption, and in rain barrels where the water is used to water vegetables.
