2018-10-17  In Canada, mine water with a pH of 2.8 has been recorded in underground mines, and measurements of 3-4 are not uncommon (Minick and Olson, 1987). Acidic mine water can often be linked to the oxidation of sulphide ores (primarily pyrite and marcasite) resulting in the generation of sulphuric acid and pH levels as low as 1.5-2 (Gunasekera, 1992).
