Airliner Potable Drinking Water as Source of Chemtrails?
MCL in the table down below means the following:
MCL is the maximum allowable amount of a contaminant in drinking water which is delivered to the consumer.
This in turn means you could drink tea or coffee brewed on potable water in a commercial airliner without getting the sensation it tastes "metallic". The only way to for you, as an attentive passenger to notice something strange with the potable water aboard, would be to see a possibly slight coloration* (due to the nanosized aluminumoxide particulates dissolved in the water) when the cabin attendant serves you a cup of hot water with a teabag beside it for you to put in. With tea or coffee that is served "ready to drink", you would see/notice nothing unusual! However, I doubt the concentration of dissolved nanosized aluminum oxide chemtrail ingredient in today's potable water is chosen so high that anyone or even a flight attendant in the gallery would notice something odd! Besides flush water for toilettes is added a blue anti bacterial additive, and who would therefore be suspicious about the washwater in the zink.
Thus, potable water as source for chemtrail ingredients can be replenished in plain sight by "honey wagon" service guys during ground stops at airports which beknownst or unbeknownst happen to provide deliberately contaminated potable water from (unserious/criminal) suppliers.
Regarding Aluminum, which is a main metal component in chemtrails (?), below table seems to indicate its presence does not produce a sensation of metallic taste, but rather affect the coloration of water it is dissolved in:
And threshold value for sensation/perception at all of something tasting sweet, savory, salty, sour and bitter:

Question: Do you know of any better scientific articles about necessary concentration of (nanosized) iron, aluminum or other metal particulates in ordinary drinking water to be perceived by test person(s)?
My question is motivated by the possibility that the "concentration" of nanosized chemtrail metal ingredients in "potable water" is chosen so it is not "perceived" by an average airline passenger if tasted or swallowed.

Why you should never drink water on a plane, according to a flight attendant.
Drinking plenty of fluids during a flight might seem like a sensible thing to do but there’s one beverage that cabin crew say you should never order onboard – water.
Considered the worst drink you can ask for while flying, a flight attendant revealed to Business Insider that you should never drink tap water mid-flight because the dirty little secret is that it can be pretty dirty.
“Flight attendants will not drink hot water on the plane,” the attendant said.
“They will not drink plain coffee, and they will not drink plain tea.”
This is because while the water tanks do get cleaned, they’re never informed when or how often.
