Not really much of a story here; they’ve been leaking all along.
The “big” one right now is about 300 gallons and is trapped above dry soil. Not in groundwater.
I was just telling my wife — these leaks are such a nano event compared to the subject of this thread.
Wonder why it’s being reported as if they recently learned of these leaks?
