To answer your question, let's address what exactly an aquifer is. One great example of an aquifer if the Florida Aquifer. It is a naturally refilling, water-permeable, rock layer with different types of rocks such as sandstone, limestone, sand, and gravel. This ground water contains freshwater that can flow in streams, rivers, ponds, and eventually into the ocean.
Because groundwater has to move through layers of soil or saturated rock, it takes a while for it to refill and flow into streams or other bodies of water. If you take a look at the Florida Aquifer, you can see that most of Florida depends on the groundwater from it as a part of their daily life, tourism attractions, and providing natural hotspots for the environment, but because of pollution and so much water usage, the Aquifer could not refill quick enough to provide enough clean water for the people or the environment.
It would be more difficult to clean pollutants from groundwater than bodies of water for multiple reasons but in this case it would be because:
B. Water moves very slowly through an aquifer, and it takes a long time to clean itself.
