The Use of Wetlands to Prevent Environmental Pollution ...

Acid Mine Drainage (AMD) (Wildeman and Laudon 1989). The most common AMD control strategy is to treat contaminated water at the dis charge point. A better altemative for pollution control at mine sites, however, is to inhibit sul phide oxidation at source (Perry and Kleinman 1991; Nawrot and Sandusky 1993; US EPA 1995).

Lambda's microbes were the first ones

A survey of constructed wetlands for acid coal mine ...

The oxidation of pyritic minerals, exposed to oxygen and water during the mining of coal, results in the formation of acid mine drainage (AMD), which is characterized by low pH and high concentrations of dissolved sulfate, iron, and other metals. Federal and State regulations require that discharges from coal surface mines meet water quality criteria. Toward that end, chemical treatment of AMD ...
