Hydrogeochemical features of surface water and groundwater contaminated with acid mine drainage (AMD) in coal mining areas: a case study in southern Brazil
(Springer, 2016-09-01)
Effects of acid mine drainage (AMD) were investigated in surface waters (Laranjinha River and Ribeirao das Pedras stream) and groundwaters from a coal mining area sampled in two different seasons at Figueira city, Parana ...
Microbial Community Structure Alogn a Horizontal Oxygen Gradient in a Costa Rican Volcanic Influeced Acid Rock Drainage System
(2020-06-22)
We describe the geochemistry and microbial diversity of a pristine environment that resembles an acid rock drainage (ARD) but it is actually the result of hydrothermal and volcanic influences. We designate this environment, ...
The Negro River (Ancash-Peru): A unique case of water pollution, three environmental scenarios and an unresolved issue
(Elsevier, 2019)
This paper is focused on the hydrogeochemical characterization of the Negro River along its course, as well as in the proposal of a functioning model for the contamination processes in order to establish potential cause-effect ...
The association of microbial activity with Fe, S and trace element distribution in sediment cores within a natural wetland polluted by acid mine drainage
(Elsevier, 2019)
Natural recovery and remediation of acid mine drainage (AMD) reduces the generation of acidity and transport of trace elements in the runoff. A natural wetland that receives and remediates AMD from an abandoned copper mine ...
