If this is well water that could be an entirely different situation and one that I know very little about, but if this is city water (particularly a
cold city) the gas bubbles are usually introduced at the reservoir.
Colder water will hold more gas in solution than warmer water, so water at the reservoir in a cold environment will actually absorb more gas from the air than it can hold when it warms up in the underground pipes. The pressure in the pipes holds the gas in solution until the pressure is instantly relieved when it jumps out of the faucet and into your glass. It isn't entirely dissimilar to "the bends" that divers are at risk of. When their bodies are pressurized, nitrogen from the SCUBA mix dissolves in the blood. If the pressure is relieved too quickly, a diver can have a nitrogen embolism from the gas popping out of fluid solution.
To the OP: did you start noticing this very recently? Like with the onset of more wintery ambient temperatures?
