Dude; that's METHANE making the water “flammable”. This has happened since there have been water wells in certain geographical areas. It's also why it is stinky gas. Untreated “Natural Gas” is odorless. The gas industry has been fracking for 60 years, and the number of times there have been any problems are close to zero. The methane in the water table depth (usually around 50 to 100 feet deep) could come & go depending on many factors. Fracking rocks at 2,000 to 5,000 feet just ain't one of them. The most likely culprits are coal mining or a tremor.

Since prehistory. Evidence has been published in the literature since before I was born.

Incidentally, for the Chicken Littles, evidence of nuclear reactions in high concentration ores have also been documented in prehistory!

The ignorant Watermelons need to rent a clue.

We're on the same page, sorta. I remarked above on the complaint of stink in a house due to "natural gas" - but natural gas is just methane - and methane isn't stinky; they have to put an odorant in it you will be able to tell if there's a leak. So we are left with the conundrum that the guy who is able to light his tap water afire is smelling something associated with methane. It doesn't jibe that the source would be a deep deposit of methane. As you say, coal mining sounds like a possible culprit. And the conclusion that it was due to fracking somewhere looks to be a "post hoc, ergo prompter hoc" error.
