no groundwater in general dos not involve water vapor as groundwater is liquid water not gaseous water (water vapor).

Evaporation from the ocean
The water on the surface of land and ocean evaporates and turns into water vapor. When the water vapor rises to a certain height, it turns into small water droplets when it is cold.
The water cycle, sometimes called the Precipitation cycle.

If the groundwater is boiling, then yes. Otherwise, probably not. (The bubbles in boiling water are made of liquid water that has rapidly evaporated into water vapor gas.)
the water vapor evaporated from the ocean
The water got in the ocean by the volcano's exploding and the vapor got in the ocean and that created the ocean water.
water vapor comes from the ocean water when it goes through evaporation.
When ocean water is warm, a lot of water vapor evaporates from it. If air laden with that water vapor rises, as it often does it will cool and the water vapor will condense, which releases energy.
In a packed or tray column where you have vapor flowing up and liquid flowing down, there is an upper limit to how fast the liquid can drain downwards. The point at which liquid cannot flow down as fast as it is coming into the column is the "flooding point". The actual flooding point is partly dependent on how fast the liquid can flow down with no vapor flowing upwards and the rate at which vapor is trying to flow upwards. Cross sections of the column occupied by vapor are not available for liquid flow - effectively reducing the cross-section for downward flow of the liquid. You also get entrainment of liquid in the upward flowing vapor and drag on the liquid as it fights the direction of the vapor flow - the vapor wants to go up while the liquid wants to go down. This additional drag also slows down the flow of liquid trying to drain downward in the column. There is an analogous condition for two-phase liquid/liquid extraction columns.
The clouds are formed by water vapor evaporating from the ocean. The water vapor condenses and falls again as rain (or snow) thereby completing the water cycle.
Water vapor is a gaseous form of liquid water. The sun naturally heats the ocean or river water to create water vapor.
