Isn't the water in Saturn's rings from the same source (i.e. the same isotope ratio)?

Deuterium to hydrogen ratios relative to Earth's Standard Mean Ocean Water (SMOW) values for Ring B, and Titan are relatively close though Enceladus and Phoebe greatly differ. Still, CI chondrite D/H ratios are closer to Earth's than any of Saturn's rings or moons.
