Mining | Water for all

The ponds are built over a seep: the seep is covered in ,limestone,, so the water coming out of the seep that fills the ,limestone, pond must pass through (and be neutralized by) the ,limestone,. Their advantage is the ability to see the ,limestone, at work; if the ,limestone, becomes coated with precipitate (thus lowering its efficiency in ,neutralizing acid,), it can be cleaned and returned to full ...

The primary compound in ,limestone, is calcium carbonate. When the calcium carbonate reacts with acidic condensate, it forms carbon dioxide, water, and insoluble salts. These salts coat the resulting ,limestone,, impairing the further ,neutralizing, effect of the media. As a result, ,limestone, media is quickly rendered ineffective and must be replaced.
