The Treatment System
Pond 1: The Acid Pool
The Acid Pool is a collection point, the beginning of the AMD treatment system. The discharge flowing from the pipes comes from the old Vinton Colliery Company Mine No. 3 and has high levels of iron and aluminum. The water flowing into this first pond is slowed down, the limestone lining of the pond quickly covered with a coating of iron oxide, the red-orange AMD sediment serving as the reference or datum point for the beginning of our treatment system. Really just a holding pond for the AMD entering the treatment system, the Acid Pool gives us the chance to explain how AMD is formed and what can be done to remediate AMD. Once the AMD leaves the Acid Pool, we actually begin the treatment system.
