Your title: "Evidence of Water on Primordial Moon, Amount Rivals Total on Earth"

The article's title: "Evidence of Water on Primordial Moon --Rivals Total on Earth"

The actual claim: "It’s not ‘liquid’ water that was measured during these studies but hydroxyl groups distributed within the mineral grain,” said Notre Dame’s Hui. “We are able to detect those hydroxyl groups in the crystalline structure of the Apollo samples." [emphasis added]

So -- Not "primordial" water, not "total", and not water at all, but present traces of hydroxyl groups in subsurface lunar minerals that are comparable to the hydroxyl groups present in similar subsurface deposits on earth.

Not remotely "water", not all all "primordial", not "total", and not "water ... Rivals Total on Earth" at all.

The linked article's author didn't remotely understand the original work and got it all wrong.
