Groundwater does not have to be pumped to the surface to use, although that would seem the most logical way to get access to it. It has no difference on the make up of the water, or the purity.
It rains then that water forms a lake or river then the water soaks down into the ground Then it must stay there for a couple of years then it forms a large amount of clean water This cycle forms groundwater.
This question must be rephrased to make it more intelligible and specific.
The larvae of .mosquito rise to the surface when about to hatch and use the strong surface tension of the water's surface as a platform to emerge. They must not get wet or they will be trapped in this meniscus.They are light enough to rest on he surface in a similar way to a pond skater whilst their wings inflate and dry.
Sanitizing is the process of reducing the number of microorganisms on a clean surface to safe levels. To be effective, cleaning and sanitizing must be a two-step process. Surfaces must first be cleaned and rinsed before being sanitized. (ServSafe Essentials section 11-21)
The single atoms of helium gas are small, and has small surface area. They must be cooled to 4K before their attractive forces cause them to condense.
it is false.

Can, yes. Must, no.
lymph
yhere is no drain it must be pumped out
There is none. Fluid must be pumped out.
yes then they must be pumped with ionic s.l.u.g.e
They must pumped actively. So energy in ATP is used.
No. Exhaust steam must be condensed back into water before being pumped back to the boiler. High pressure exhaust is often used to heat production or heating equipment, returned to a condensate tank then pumped to the D/A before being returned to the boiler. Low pressure (vaccuum) exhaust is condensed by a jet condenser or shell and tube condenser before being returned to the D/A.
So the garbage does not contaminate the water supply
