Because of it wide liquid temperature range gallium finds uses for high-temperature thermometers. It is used as a wetting agent in tin-lead solders, which also decreases the solders susceptibility to oxidation.
Gallium is used as an electron carrier in silicon semiconductors. Gallium arsenide (GaAs) is used as a semiconductor and in rectifiers that operate at temperatures to 316°C (600°F). Gallium arsenide is capable of converting electricity directly into coherent light. It is also used in lenses in CO2 laser systems.
As an alloying agent to reduce the melting point of the alloy.
Magnesium gallate containing divalent impurities such as Mn2+ is finding use in commercial ultraviolet activated powders phosphors.
Gallium selenide (GaSe) and gallium triiodide (GaI3) are used on electronic applications.
While not considered toxic, the data about gallium are inconclusive. Some sources suggest that it may cause dermatitis from prolonged exposure; other tests have not caused a positive reaction. Like most metals, finely divided gallium loses its luster and powdered gallium appears gray. Thus, when gallium is handled with bare hands, the extremely fine dispersion of liquid gallium droplets, which results from wetting skin with the metal, may appear as a gray skin stain.

Gallium is not produced in the United States, and demand is satisfied by imports, primarily high-purity material from France and low-purity material from Kazakhstan and Russia.

I think your last citation may provide a clue. Although some may gravitate to the more 'exotic' explanations, my guess is that this is residue from a manufacturing process --- if not locally then possibly coming from Russia carried on high altitude air currents. Given the relatively lax environmental controls in Russia they could be spewing huge amounts of this material into the atmosphere.

Yes, but this article discovered hight levels of gallium in ARIZONA, not the entire continental United States. If it were found everywhere in the same concentration your theory might work.

Is ASU or the 'Pheonix Project' following Purdue's research on hydrogen production?
Just did a quick search but didn't find anything that was up to date.
"This technology is feasible for commercial use," Woodall said. "The waste alumina can be recycled back into aluminum, and low-cost gallium is available as a waste product from companies that produce aluminum from the raw mineral bauxite. Enough aluminum exists in the United States to produce 100 trillion kilowatt hours of energy. That's enough energy to meet all the U.S. electric needs for 35 years. If impure gallium can be made for less than $10 a pound and used in an onboard system, there are enough known gallium reserves to run 1 billion cars."
