I'd wager 99.9% of the gen pub doesn't even realize avgas (or that there even a thing called avgas for that matter ) still has lead in it, I'd also wager that most probably don't even know the history of lead as an additive to motor fuels, and the fact that it has been largely phased out. It's probably one of the biggest potential sh*tstorms that could hit general aviation, if the wrong crowd got riled up about it. Bigger then any noise and landing off airport issues.
My last batch, 280 gallons, of E-0 premium cost me $2.50 a gallon, while avgas in my area was $4.25-75 or so. Since my modded Rotax can safely burn low octane/regular at my field elevation, I don't worry about any octane loss in storage. I have never had any fuel issues whatsoever, and have been using mogas exclusively for decades.
I recently was doing some crane work at a new gas station going in my area. The way they deal with the buried tanks was very interesting. They had "special" inspectors there, state or federal, maybe both, who watched the entire process, clipboards and cameras in hand. The way they run the lines from the tanks to the above ground tanks was a whole nother big deal, safeguards upon safeguards, leak detectors up the wazoo. I've also worked out at the big tank farm where our fuel comes in from SLC's pipeline. Overall it was reassuring to see what goes into what comes out of the nozzle, and it's amazing it's as cheap as it is.
