I would be very cautious to put kerosene in drinking water. Lipid pneumonia is caused by inhaling petroleum-based products when swallowing them. My 86-yr-old mother tells me stories about my grandmother giving everyone a teaspoonful of turpentine back when she was a kid for some kind of treatment, and I wonder how they all made it to adulthood. Some of her siblings were a little crazy though, LOL.
