Acid Mine Drainage Definition
Acid Mine Drainage (AMD) is a natural phenomenon of a contaminated run-off formed by a chemical reaction between air, water and rocks containing sulfur-bearing minerals (Pyrite). The increased soil excavation of mining activity further accelerates AMD formation.
Acid Mine Drainage Effects on the Environment
Acid mine drainage is a problem because it is usually very acidic, and rich in sulfates, hardness and dissolved heavy metals. The main concerns of regarding acid mine drainage are the contamination surface drinking water source or penetration into the local aquifer, but acid mine drainage also has effects on humans.
Acid mine drainage has a severe impact on aquatic wildlife including plants, animals and fish. In serious cases, impacted water can have pHs of less than 4. This can disrupt reproduction and growth.

Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.
