Abstract
The study was carried out in the mineral field of Santa Lucia – Castellano’ located to the northwest of the Pinar del Rio, Cuba, which had two main mines: Santa Lucia and Castellanos. It was in these mines where the miner–metallurgic activities like gold and silver extractions and pyrite processing were developed. The aim of the study was to diagnose the major environmental problems related to the hydrology in this area created by wastewaters that formed the acid drainage, and the contaminations with high toxicity levels. The quality of waters was corroborated, which found that the most damaged areas were: quarries, sterile deposits of the mine, and the mangrove ecosystem due to the accumulations of superficial currents and airborne transportation of fine materials. Thus, it enabled the proposal of the necessary actions to mitigate and supervise the area.
