Mining and Water Pollution — Safe Drinking Water
2016-12-17 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.
