Preliminary study of the water geochemistry in an abandoned mine area of the High Moulouya District (NE-Morocco)
The Haute Moulouya District, a zone of potential tourism development, occupies a strategic position in Morocco, and has important and diversified natural resources including mines and waters. The mine areas were exploited since antiquity for the extraction of lead, zinc, copper and iron. In the early 20th century, massive industrial mine exploitation began. After its closure in 1983, the mining district retained some environmental problems, due to disturbance of nature and the liberation of sulphate from pyrite alteration. Acid mine drainage could become serious if the acidity isnt rapidly neutralized by limestones. The water chemistry changes considerably between the mines and the surrounding areas. This study demonstrates contamination of local waters by heavy metals and discusses hidden mineralizations.
