I would guess that the vast majority of pollution in ground water comes from people discarding chemicals and materials in low line areas and eventually rain water will force those chemicals and materials through the ground and into the groundwater. We've also heard of, we're well aware of people who have wells and use the wells as a disposal site for toxic chemicals.
Usually, when a factory empties there waste, it gets into the ground, then soaks in until it gets to water then it's very easy for it to spread
The air that goes in the aquifers or the polluted water the goes into the water or the dirt the goes into the aquifers.
The most easily polluted groundwater reservoirs are water table confined aquifers.
Groundwater and aquifers can both be tapped by wells.
groundwater is replenished slowly

Aquifers are groundwater.
The two types of groundwater are: Wells and Aquifers.
It very much depends on the area; some groundwater is polluted but other groundwater is pure.

It depends on the situation. In general, groundwater is better because the earth filers the water. However, if the soil in that region is heavily polluted, the water will also become polluted. Surface water in constantly polluted by animal feces, human pollution, and atmospheric pollution.
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
