I agree with VF.
For a short time back in the early 80s, I lived at 41 15' 3.0" N, 80 43' 49.4" W.
The well water was just just short of being almost Diesel fuel. Not usable for drinking, cooking, bathing, washing dishes, or leaving the bathroom door open (not kidding)... I expect the EPA would not allow it to be flushed down the crapper to a septic system (again, not kidding).
If a glass of water was allowed to sit for a day, the globules(?) of oil were too large to be lifted out with a small red spoon the size that McDs formerly used for coffee but customers re-purposed for other things (it was the very early 80s).
It is, and was at the time, in the middle of housing developments covering huge areas.
That house was the only one with any water well issues, as far as I knew, or the people I knew where aware of, and people in a housing development know a lot of stuff about a lot of people.
A bad water well is not necessarily due to gas/oil wells or fracing.
Under the WTF heading, I own something like 1% of 1% of 1% of 1/10th of 1% of a newly drilled gas well.
They decided to "postpone turning it on" until wholesale prices went higher.
Supply and Demand.
