(And I've heard Herb express a theory that anything different on Geyser Hill can be a precursor for Giantess: go Goggles(es) go!) Geysers and their associated aquifers can be very complex entities, and the subsurface connections (say, the one that connects Beauty and Chromatic) can be quite clear or really esoteric (there is no evidence to my knowledge that Atomizer and Artemesia are connected, though they're not much farther apart than B&C). I don't know if she ever got this assay complete, but a geothermal researcher named Cathy Nist had a research proposal accepted that allowed her to put a chemical salt of some sort into Splendid and periodically take samples from the other geysers in the Daisy group to track the way it diffused. It's a great question; looking for answers would make for a whole bunch of really good (funded) research studies.
