They're really quite fragile creatures, and they occur naturally throughout much of the world. I don't think there would be any adverse reaction
to them -- when we used them years ago to treat contaminated soil, they'd stay alive as long as we kept their fairly specific environmental
conditions going. If we could keep them alive, they'd continue until they ran out of food (hydrocarbons), and then die. Their by-products are
CO2 and water. They DO depleate some naturally-occuring minerals, such as carbon and phosphorus, possibly others that I can't recall.
They do require oxygen, so it's possible that they might starve an immediate body of water of some of its oxygen as well. I haven't studied their
use on contaminated water.
