> A plugged well is injected with high pressure concrete to/past the impermeable rock layers, past the multiple steel/concrete well casings that travels through aquifers.
Now imagine having hundreds of old oil wells around, some of them are rusted out and can totally transfer fluids up from down under to the water table level.
They probably need to inspect every well and make sure it's properly plugged with concrete, not just a cap on top.
