There are "fine sandy gravel aquifers" everywhere and some of them may be polluted, but your question is too vague. You must at least state an area that you are talking about.
Gravel grades for driveway construction typically range from fine to coarse. Common grades include fine gravel, medium gravel, and coarse gravel. Fine gravel is smaller in size and provides a smoother surface, while coarse gravel is larger and offers better drainage. Medium gravel falls in between the two in terms of size and is a popular choice for driveways.
The different gravel grades available for landscaping projects include fine gravel, medium gravel, and coarse gravel. Fine gravel is small in size, medium gravel is slightly larger, and coarse gravel is the largest. Each grade is used for different purposes in landscaping, such as pathways, driveways, or decorative accents.

Yes. You can layer substrate in any tank. However, if your plants can grow fine in gravel, they can grow fine in colored gravel, just make sure the colored gravel is safe for aquariums.

Some beaches consist of coarse gravel. Shall I order fine or coarse gravel for the concrete walkway?
Gravel can be composed of varying sizes of stone, sand, and fine dust, with the coarse stone measuring up to about 2 inches. Large stone is often referred to as ballast or sometimes, pit run. Even larger stone (6" to 24") is called rip-rap. Rip-rap is used to armor the soil to prevent erosion from water runoff. If you are using boulders or rip-rap, then gravel would probably be considered a fine aggregate. But if you are using gravel under a new sidewalk, say, then gravel would be somewhat coarse compared to the sand and fine dust in it.
Nope. Rounded gravel is fine.
