Does anybody really know how much "Stuff" actually grows in an RV fresh water tank? Typically, it's full of or has water in it and is somewhat sealed from the outside. It's always dark in it's compartment which to algae means no light to produce food and grow. There are trace amounts of nutrients for stuff to grow from. The RV fresh water tank is really an inhospitable place for life.
I'd guess that airplane freshwater tanks have a similar environment - tanks are sealed and dark, are refilled frequently, and get plenty of agitation.

But a new study shows it's not just the tray table or seat-back pocket that could be harboring germs and bacteria. The tap water on both major and regional U.S. carriers was found to be contaminated with varying levels of E. coli and coliform, according to the newly released 2019 Airline Water Study conducted by DietDetective.com and Hunter College NYC Food Policy Center.
Interesting article. This quote is pretty much what reasons I think airline water may be more contaminated.
""Because aircraft water comes from locations via temporary connections, aircraft drinking water quality depends on a number of factors (e.g., the care used to board the water, the water transfer equipment (such as water cabinets, trucks, carts, and hoses), and the operation and maintenance of the onboard water system)," the EPA said"
The care we take with our own water system is much higher during handling than a commercial airline's employees give to the aircraft.
