A layman's description. When de-oxygenated water reaches a source of oxygen, these commonly called iron bacteria convert dissolved iron into an insoluble reddish-brown gelatinous slime that discolors stream beds or can stain plumbing fixtures, and clothing or utensils washed with the water carrying it. Organic material dissolved in water is often the underlying cause of an iron-oxidizing .Dec 17, 2016 · Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
