GG, we all want a life of sacred purity. To have no trace of anything anywhere is not going to happen in your lifetime. The problem with having fuels in tanks is that nature is relentless, loves the idea of entropy and is prone to making holes in tanks, one way or the other. Engines don't burn every last molecule of fuel and catalytic converters don't catch every last molecule either. So, if you have engines, tanks and fuel, you are going to have fuels in your drinking water. Not to mention engine oils, shampoo, and everything else.

The whole point of the tank replacement process and redesigning them from a plain cylinder of mild steel to double-walled fibre glass in concrete box pits and other engineering tricks of the trade was to reduce escape of fuels. Which, contrary to Elroy's idea, they do. The amount of fuel leaking into the ground is vastly reduced from the bad old days, though as I said, I was bemused to see a drip, drip, drip of diesel [or some other heavy liquid] from an above-ground tank in Saint Quentin La Poteri, onto the ground from an overflowing leak-catching bucket, and from there into the ground water which runs into the stream where the Roman Empire got its water via the Pont du Gard. Such an odd thing to be happening in the 21st century.
